Few homeowners expect a driveway to involve planning rules, yet it is one of the most common places people get caught out. The paving itself is rarely the problem. The trouble usually comes from the surface you choose, the access onto the road, or the type of property you live in. At JPD Landscaping & Building Services, we have installed driveways across South East London for over 15 years, and the permission question comes up on almost every project. This guide is a full checklist of the situations that can trigger permission, written in plain English, so you know what to check before any work starts. A quick note first. This is general guidance based on our experience, not legal advice, and rules can differ between areas and change over time. Always confirm your own situation with your local council. Do You Need Planning Permission? Many driveways do not need planning permission, but several common situations do. The three that come up most are using a surface that does not let water drain away over a large front garden area, creating a new vehicle access across the pavement, and living in a conservation area or a listed building. Situation Permission Likely Needed? Paving a front garden with a surface that lets water drain through Usually not Paving a large front garden area with a non-permeable surface and no drainage to a lawn or border Often yes Creating or widening a vehicle access across a pavement or verge Separate council approval, often yes Property in a conservation area, or a listed building Check first, extra rules may apply Flats and maisonettes Often yes, as normal rights may not apply Why These Rules Exist It helps to understand the reasoning, because it makes the rules far easier to follow. For many years, homeowners across the country replaced front lawns with solid, sealed paving. Each driveway looked harmless on its own, but together they sent large volumes of rainwater straight into the drains during heavy storms, which added to the risk of flooding. The surface water rule was introduced to deal with exactly that problem. It is not about how your driveway looks. It is about where the rain goes once it lands. Keeping that in mind makes it much easier to judge whether your own plans are likely to cause an issue. The Front Garden Surface Rule The rule that catches most people out relates to the surface itself. In England, paving over a front garden is generally allowed without planning permission, provided the surface is permeable, meaning water can drain through it. If you use a surface that does not let water through, and the area is larger than 5 square metres, you will usually need planning permission. The exception is where the rainwater runs off to a lawn, a border or another permeable area within your property. This rule exists to reduce the amount of surface water flowing into the drains, which helps limit flooding. It is also the reason that the surface you choose and the way you drain it matter just as much as how the driveway looks. What Counts as Permeable? A surface is treated as permeable if water can pass through it, or if it is drained to a permeable area. Common examples include: The key point is that the whole system needs to work, not just the top surface. A permeable surface laid on an impermeable base may not meet the rule in practice. If you are still deciding between surfaces, our comparison of resin bound and block paving driveways explains how each one handles water. Designing Drainage That Actually Works Where standard paving is used, the drainage design is what keeps the project within the rules, so it deserves proper attention. The paving needs a gentle fall that carries water towards a lawn, border or soakaway, rather than towards the house or the pavement. The receiving area also has to cope with the volume of water it will receive, which depends on the size of the drive and the type of ground. Heavy clay soil drains slowly, so a soakaway or border in clay ground may need to be larger, or supported by a different drainage route. Our guide on patio drainage problems and fixes explains how falls and outlets behave in practice, and the same principles apply to a driveway. Getting this right at the design stage is far easier than correcting a puddle problem once the surface is down. Dropped Kerbs and Vehicle Access A dropped kerb is a separate matter from the paving. If your driveway needs a vehicle to cross a pavement or grass verge, the council has to approve it, and the kerb must be built by an approved contractor. This approval is separate from any planning permission for the driveway surface, and it is one of the most common causes of delay. There is a further rule for busier roads. If your driveway will give a new or wider vehicle access onto a classified road, which includes A, B and C roads, you will generally need planning permission for the access itself. The process, timescales and fees vary from one council to another. We recommend contacting your council early, particularly if you are creating a driveway where none exists, because the kerb approval can take longer than the building work itself. Conservation Areas, Listed Buildings and Article 4 Directions Some properties have extra restrictions that remove the usual freedoms. These are easy to overlook, because a driveway can look like a simple, low key project. If your home is in an older part of South East London, it is well worth checking whether any of these apply before you commit to a design. Finding out halfway through a project is far more stressful and expensive than checking at the start. Our guide on planning permission for patios covers conservation area checks in more detail, and the same approach works for driveways. Gates, Walls and Boundaries A driveway

A new driveway is one of the biggest outdoor spending decisions most homeowners make, so it makes sense to understand the price before you start collecting quotes. Block paving remains one of the most popular choices in the UK, thanks to its smart appearance, its strength under vehicles, and the fact that individual blocks can be lifted and replaced if they are ever damaged. At JPD Landscaping & Building Services, we have installed block paving driveways across South East London for over 15 years. This guide explains what a block paving driveway really costs, what pushes the price up or down, how it compares with other surfaces, and what a typical project looks like. Average Block Paving Driveway Cost A standard block paving driveway typically costs between £100 and £130 per square metre, including materials and labour. For most homes, that puts the total somewhere between £1,500 and £6,500, depending on the size of the drive and how much groundwork the site needs. Driveway sizes vary widely across South East London, from compact single car drives to wide frontages that take several vehicles. The table below shows what the per square metre rate means in practice. Driveway Size Approximate Area Estimated Cost Small single car 15m² £1,500 to £1,950 Single car 20m² £2,000 to £2,600 Two cars 30m² £3,000 to £3,900 Wide two car 35m² £3,500 to £4,550 Large driveway 40m² £4,000 to £5,200 Extra large driveway 50m² £5,000 to £6,500 These figures assume reasonably straightforward ground. Excavation, drainage and access can all change the final price, and we cover each of them below. What the Price Includes When we quote a per square metre rate, it covers the whole job rather than just the blocks. A proper driveway is built in layers, and each layer is part of what you are paying for. Be wary of a quote that looks much cheaper than the rest. It often means the sub-base has been reduced, or the edge restraint left out, and those are exactly the shortcuts that cause driveways to fail. What Pushes the Cost Up Two driveways of the same size can cost very different amounts. Here are the factors that make the biggest difference. Excavation and Groundwork This is the biggest cost driver beyond the paving itself, and it is the factor most homeowners underestimate. A driveway carries far more weight than a patio, so it needs a deeper and more carefully compacted sub-base. Digging out that depth, and removing whatever is already there, takes time, machinery and waste disposal. If you are replacing an existing surface such as old tarmac, concrete or a failed block paved drive, the cost of breaking it out and taking it away can add noticeably to the total. Sloped sites and soft ground can add further work, because the base needs extra attention to stay stable. If your front garden has a significant level change, it is worth reading about retaining wall installation, since managing the slope properly is often part of the groundwork. Drainage and UK Rules In the UK, rules on front garden surfaces exist to reduce surface water running into the drains. As a general guide, paving over a large area of front garden with a surface that does not let water through may need planning permission, unless the water drains to a lawn or border, or the surface is permeable. How we handle this depends on the property, so we check the site first and decide case by case. The solution might be permeable block paving, where water drains through the joints, or standard block paving with a soakaway or drainage channel. Each carries a different cost, which is why drainage is worth discussing early. Our guide on patio drainage problems and fixes explains how water behaves on paved surfaces and why the fall and outlets matter. Dropped Kerbs and Access If your driveway does not already have a dropped kerb, you will need the council to approve one and have it built by an approved contractor. This is a separate cost from the paving, and it can also take time to arrange. If you are creating a new driveway, it is best to raise this at the start so it does not hold up the project. Access matters too. If materials and machinery cannot reach the site easily, the work takes longer and costs more. Pattern, Blocks and Edging The look you choose also affects the price. A simple stretcher bond or basket weave is cheaper to lay than a herringbone pattern, which takes longer but is stronger under vehicles. Premium blocks, multiple colours, decorative borders and detailed edging all add to the cost, although they can make a driveway look far more distinctive. If you are weighing up border options, our guide to patio edging ideas covers setts, brick and metal edging in detail, and much of it applies to driveway borders too. How Block Paving Compares with Other Surfaces Block paving sits in the middle of the driveway market. It costs a little less than resin or natural stone, but more than gravel or tarmac, and it offers a combination of strength and good looks that few other surfaces match. Surface Cost Compared with Block Paving Key Point Gravel Lower Affordable, but loose and needs topping up Tarmac Lower Practical, but plain and hard to repair neatly Block paving Mid range Strong, attractive and easy to repair block by block Resin bound Higher Smooth and permeable, with a higher price Natural stone Higher Premium look at a premium cost One of block paving’s real advantages is repairability. If a section is damaged or stained, you can lift the affected blocks and replace them, rather than patching or resurfacing the whole drive. Why Block Paving Is Worth the Cost For many homeowners, the extra cost over gravel or tarmac is justified by what block paving delivers. Those benefits depend on one thing, which is a properly built base. That is where most failures start. Why

Most patios are square or rectangular, and for good reason. They are simple to lay and easy to fit against a house wall. A circular patio is different. It softens the hard lines of a garden, creates a natural focal point, and gives a space the feel of a destination rather than an extension of the house. At JPD Landscaping & Building Services, we have built circular patios across South East London for over 15 years. This guide shares design ideas that work in real gardens, explains how to choose the right size, and covers the mistakes that stop a circular patio looking as good as it should. Why Choose a Circular Patio? A circle works against the grain of most gardens, which are made up of straight fences, straight walls and rectangular lawns. That contrast is exactly what makes a circular patio so effective. It breaks up the geometry, draws the eye, and gives the garden a sense of flow. A circular patio also works well as a separate zone. Placed away from the house, it becomes a destination, somewhere you walk to for a coffee, a fire pit evening or a quiet corner. In smaller gardens, a circle can also make better use of space than a large rectangle, because it leaves room for planting and curves around it. There is a practical side as well. A round table and chairs sit naturally on a round patio, with no awkward corners left empty. The whole surface feels used. Circular vs Square Patios Before settling on a circle, it helps to know how it compares with a standard layout. Factor Circular Patio Square or Rectangular Patio Visual effect Soft, eye catching focal point Neat, practical, blends with the house Cutting and waste Higher, because slabs are cut to the curve Lower, most slabs are laid whole Labour time Longer, set out and cut carefully Shorter and more straightforward Overall cost Higher Lower Best for Feature areas and destination spaces Main entertaining areas against the house A circular patio does cost more than a square one of similar area. There is extra cutting and waste, and more labour is needed to set out the circle and cut the edge slabs accurately. For many customers the visual payoff is worth it, but it is worth budgeting for from the start. Our guide on how much it costs to landscape a garden shows where a feature patio fits into a wider project budget. How Big Should a Circular Patio Be? Most of the circular patios we build in South East London fall between 2.5 and 3.5 metres across. That is large enough to be genuinely useful, yet small enough to sit comfortably in a typical garden. The right size depends on what you plan to put on it, so think about furniture before you decide. Diameter Typical Use About 2.5m A bistro table and two chairs About 3m A four seat dining set with room to move About 3.5m A larger dining set, or a fire pit with seating around it These are guides rather than fixed rules. Remember to leave space around the furniture, because chairs need room to pull out. As a rough rule, allow at least a metre between the edge of the table and the edge of the patio so people can sit and stand comfortably. Choosing Paving for a Circle The paving you choose affects both the look and the cost of a circular patio. Natural stone gives a warm, traditional character, and our guide on how to build a stone patio explains what to expect from the material. Porcelain offers a very consistent, low maintenance surface, while good concrete slabs suit tighter budgets. Whichever material you choose, remember that every edge slab will need cutting. Harder, denser materials take more time to cut cleanly, which is one reason the paving choice has a bigger effect on the price of a circle than it would on a simple rectangle. Eight Circular Patio Ideas 1. Pre-Cut Circle Kits The simplest route to a circular patio is a pre-cut circle kit. These come as a set of shaped pieces designed to fit together into a perfect circle, usually in a fixed diameter. Because the cutting is done at the factory, the finished edge is accurate and consistent. Kits are a popular choice because they reduce waste and make the layout straightforward. They are also available in a range of finishes, including natural stone and porcelain effects, so you can match the circle to the rest of your garden. 2. Cut Slabs for a Custom Size If you want a circle in a specific diameter, or you are working with paving you already have, individual slabs can be cut to fit. This gives you complete control over the size and the layout, and it lets you match the paving to the rest of your garden exactly. The trade-off is time and skill. Cutting slabs to follow a curve takes care, and it needs the right equipment to get a clean, accurate edge. This is the method we use most often, and the one where experience makes the biggest difference to the finished result. 3. A Contrasting Ring Border A ring of contrasting paving or setts around the outside of the circle adds definition and a designed feel. Darker setts around lighter paving, or the other way round, make the circle stand out clearly against the lawn or planting. The border also solves a practical problem. It gives the cut slabs a neat finish at the curved edge, and it acts as a firm restraint that keeps the whole circle stable over time. 4. A Fire Pit Centrepiece A circle and a fire pit are a natural pairing. Placing a fire pit at the centre gives the patio an obvious focal point and draws people in around it. Seating can be arranged in a ring around the fire, and the round shape makes every seat part of the conversation. For

Edging is the part of a patio that most people think about last, yet it does two very important jobs. It gives your patio a clean, finished look, and it holds the whole surface in place. The right edging can make a simple patio look designed, while the wrong choice, or poor fitting, can leave you with loose slabs and gaps within a couple of years. At JPD Landscaping & Building Services, we have installed patio edging in every style across South East London for over 15 years. This guide shares eight edging ideas that work well in real gardens, how to fit them so they last, and the mistake that causes most edging problems. Why Patio Edging Matters Patio edging is more than decoration. It acts as a restraint around the outside of the paved area, stopping slabs from creeping outward under foot traffic, rain and ground movement. Without a solid edge, the outer slabs gradually shift, joints open up, and the whole patio starts to loosen. Edging also separates your patio from lawn, gravel or planting beds, which keeps soil and grass from spilling onto the paving and makes the space easier to maintain. If your patio sits next to a lawn, it is worth reading about our artificial lawn installation service too, since a crisp edge makes a big difference to how both surfaces look together. Visually, edging frames the patio in the same way a mount frames a picture. Which Patio Edging Is Best? There is no single best option, because the right edging depends on your garden style, your paving, and how the patio sits within the garden. We recommend choosing case by case rather than defaulting to one material for every project. The table below gives a quick overview of the main styles. Edging Style Best For Matching paved border A seamless, polished finish Stone setts Traditional gardens and a durable edge Brick or block paving Classic looks and defined borders Timber sleepers Natural styles and raised areas Metal edging Modern, low profile finishes and curves Eight Patio Edging Ideas 1. Matching Paved Border Using the same paving as your main patio, laid as a border, is the simplest way to get a neat, cohesive edge. Because the material matches, it blends in and keeps the design uncluttered. This works particularly well for small gardens, where too many materials can make the space feel busy. It is also the easiest option to plan, since you are ordering one material rather than coordinating two. If you are still choosing your main paving, our guide to how to build a stone patio explains what to expect from natural stone as the base material for this kind of border. 2. Stone Setts Stone setts are small, durable blocks that make a strong, traditional edge. They can be laid in a single row or a double row, and they pair well with both natural stone and porcelain paving. Setts also help hold the outer edge of the patio firmly in place, which is a practical benefit on top of the good looks. A double row gives a more substantial, heritage feel, while a single row keeps things lighter and more contemporary. Either way, setts reward careful setting out, because uneven spacing is very noticeable in a small, repeated unit. 3. Brick or Block Paving Edging Brick or block edging gives a defined, classic border and works especially well with traditional properties and period homes. It is also a good way to introduce a warmer colour around a neutral patio. Like setts, it needs to be properly bedded and backed to stay put. Laying the bricks on their side, in a soldier course, gives a clean, formal line, while laying them end on creates a slightly chunkier border that stands out more against the main paving. 4. Timber Sleepers Timber sleepers suit natural, informal gardens and are a popular choice where a patio meets a planted area. They are also useful for edging raised patios, where they can retain the ground level. Choose treated or hardwood sleepers for longevity, since untreated softwood will deteriorate faster in damp conditions. If your patio sits at a different level to the rest of the garden, sleepers can double as a low retaining edge. Our sleeper retaining wall installation guide covers how to fix them securely when they are doing that heavier job. 5. Metal Edging Steel or aluminium edging strips give the cleanest, most modern finish. They sit low, almost invisible, and create a crisp line between patio and lawn or gravel. Metal edging is also flexible enough to follow gentle curves, making it a good option for shaped patios. Because it is so slim, metal edging works best where the paving itself is already well restrained, or where it is mainly doing the job of separating the patio from lawn rather than holding heavy slabs in place. 6. Contrasting Colour Border A border in a contrasting shade, such as darker setts around a light patio, creates strong visual impact for relatively little extra cost. Clean straight lines with a contrasting border make a patio look deliberately designed, and the effect works in both modern and traditional gardens. The key is to keep the contrast deliberate. One clear border colour looks designed, while several competing shades can look busy, particularly in a smaller garden. 7. Curved Edging Curves soften the hard geometry of paving and help a patio flow into the surrounding garden. Small setts or flexible metal edging both work well for curved edges. Curves take a little more time to set out and lay, but the result can make a garden feel more natural and relaxed. For a gentle curve, a flexible strip often does the job neatly, while tighter curves usually suit small setts, which can be laid in a smooth arc without awkward cuts. 8. Raised Edging with Planters or Seating For a raised patio, the edge can do more than contain the paving. Building planters or

A standard patio base, with its typical 100mm compacted hardcore and 75mm bedding layer, works well for straightforward, level ground with reasonable drainage. But not every garden fits that description. Clay soil, sloped plots, and gardens with generally poor drainage all genuinely change how thick your base needs to be, and by how much, to properly support a patio over the years. At JPD Landscaping & Building Services, we’ve built patios on all kinds of difficult ground across South East London for over 15 years. This guide focuses specifically on how clay soil, sloped gardens, and poor drainage affect base thickness, and the assessment step that matters more than any fixed number we could give you. Our general guide on how to lay a patio covers the standard specification this guide adjusts away from, so it’s worth reading both together. Patio Base Thickness on Difficult Ground There’s no single fixed increase we apply universally here, since the right thickness genuinely depends on your specific ground conditions assessed case by case. That said, a few patterns hold consistently across the difficult ground types we deal with most often. Clay Soil Concern: Drainage AND shrink-swell movementBase Adjustment: Case by case, based on soil assessment Sloped Gardens Concern: Water flow and structural stability across the slopeBase Adjustment: Stepped or terraced base with retaining structures Poor Drainage Concern: Water not dispersing naturally through the groundBase Adjustment: Increased hardcore depth for better natural drainage Why the Standard Base Isn’t a Universal Answer It’s worth being clear from the outset why a single specification can’t cover every garden. The 100mm hardcore and 75mm bedding figures quoted for a standard patio assume the ground beneath is reasonably firm, drains adequately on its own, and sits at a fairly consistent level across the whole patio area. Once any one of those assumptions stops holding true, whether because the soil itself behaves differently, water doesn’t disperse the way it should, or the ground simply isn’t flat, the standard specification stops being a reliable guide and starts being a guess. This is exactly why every difficult ground project we take on starts with understanding what’s actually beneath the surface, rather than applying a textbook figure and hoping the ground cooperates. Why Clay Soil Genuinely Complicates Base Thickness Clay soil presents two separate concerns that both affect how your patio base needs to be built, and it’s worth understanding both rather than treating clay as a single, simple issue. Because both of these factors are genuinely at play with clay soil, and their severity varies significantly from one garden to another, we don’t apply a fixed thickness increase across every clay soil project. Instead, this is assessed case by case, based on the specific soil conditions found at your property, rather than a blanket number that might be either insufficient or unnecessarily excessive for your particular situation. Understanding Shrink-Swell Movement in More Detail It’s worth explaining shrink-swell behaviour a little further, since it’s the less intuitive of clay’s two challenges and the one homeowners are least likely to have encountered described elsewhere. Clay particles are extremely fine and have a genuine capacity to absorb water into their structure, which causes the soil to physically swell in volume during wet periods. As the same soil dries out, whether through a warm summer or simply less rainfall over a stretch of weeks, it contracts again, sometimes visibly, with surface cracking appearing in exposed clay ground during a dry spell. This cycle repeats every year to some degree, and its intensity depends on the specific clay content and composition of your soil, along with how exposed that ground is to seasonal drying, for instance through nearby tree roots drawing out moisture more aggressively than open ground would experience. A patio base built without accounting for this ongoing movement can develop cracking or unevenness over several years, not because anything was built badly in an obvious sense, but because the ground beneath it kept moving in ways the base wasn’t designed to accommodate. How This Movement Actually Affects a Finished Patio The practical consequence of shrink-swell movement typically shows up gradually rather than as a single dramatic event. A base sitting on soil that swells and contracts unevenly across its area, perhaps due to varying moisture retention from one section to another, can develop the same kind of localised settling covered in our guide on patio drainage problems and fixes, where a puddle in the middle of an otherwise well draining patio pointed to sub-base movement beneath specific slabs rather than a fault with the overall design. Clay soil makes this particular failure mode considerably more likely if the base wasn’t properly assessed and specified for the ground it sits on, which is exactly why we treat clay differently from straightforward, stable soil types from the outset. How Sloped Gardens Change the Approach For sloped gardens, thickness alone doesn’t solve the underlying challenge, which is really about managing water flow and structural stability across a garden that isn’t naturally level. Our typical approach combines a stepped or terraced base design with retaining structures, rather than simply varying the hardcore depth uniformly across the slope. This stepped approach breaks the sloped area into more manageable, effectively level sections, each properly supported and retained, rather than trying to build a single continuous base across ground that naturally wants to move water and soil downhill. Retaining structures then hold each stepped section in place, managing the practical challenges that a slope presents beyond what base thickness alone could address. Why Retaining Structures Do the Real Work on a Slope It’s worth being specific about the division of labour here, since it’s easy to assume a sloped garden just needs a thicker base at the lower end to compensate. In reality, the retaining structure is doing the genuine engineering work of holding back soil and managing the level change safely, while the patio base itself, within each stepped, now effectively level section, can follow a broadly standard specification

Choosing between a poured concrete patio and a traditional paved slab patio isn’t a case of one being universally better than the other. Both are genuinely solid options, and in our experience, the right choice really does come down to your specific priorities around cost, style, and how you want to handle any future repairs. At JPD Landscaping & Building Services, we’ve built both poured concrete and paved slab patios across South East London for over 15 years. This guide gives you an honest, practical comparison of the two, covering the genuine advantages and downsides of each, so you can decide what fits your garden and priorities best. Comparing Concrete and Paved Patios We don’t have a single go-to recommendation here, it’s roughly an even split depending on what matters most to you. Poured concrete offers a lower cost for large areas, a seamless finish, and faster installation once ground preparation is done. Paved slabs offer far greater style choice and, importantly, are much easier to repair, since you can replace individual damaged slabs rather than needing to break out a whole section. Cost for Large Areas Poured Concrete: Generally lowerPaved Slabs: Generally higher Style or Material Choice Poured Concrete: Limited without added finishesPaved Slabs: Wide range (stone, porcelain, colours, patterns) Repair Approach Poured Concrete: Difficult, often needs breaking out a sectionPaved Slabs: Easy, replace individual damaged slabs Main Risk Poured Concrete: Cracking over time without proper expansion jointsPaved Slabs: Jointing maintenance over time Why This Decision Deserves More Than a Quick Guess It’s worth being upfront about why we treat this as a genuine, priorities based decision rather than pushing customers toward whichever material happens to be more profitable for us to install. A patio is a long term feature of your garden, typically expected to perform well for a decade or more, and the two materials genuinely diverge in how they age, how they’re repaired, and what they cost across different project sizes. Getting this decision right at the planning stage avoids the frustration of a homeowner discovering years later that their chosen material doesn’t suit how they actually use, maintain, or eventually need to fix their patio. Why Poured Concrete Has Genuine Advantages Poured concrete brings a real set of practical benefits, particularly for larger patio areas. These advantages make poured concrete a genuinely strong option for larger, more budget conscious projects, or where a clean, modern, seamless look is the priority. The underlying mixing and pouring technique that makes this fast, seamless installation possible is covered in detail in our guide on how to lay a concrete base, which applies just as much to a poured patio surface as it does to a shed base or other garden slab. What a Finished Concrete Patio Surface Can Actually Look Like It’s a common misconception that poured concrete automatically means a plain, grey, purely utilitarian surface, and it’s worth being clear that this isn’t quite accurate. A range of finishing techniques can be applied to a poured concrete patio to considerably improve its final appearance beyond a basic flat pour. Exposed aggregate finishes, where the surface is treated to reveal the natural stone aggregate within the concrete mix, give a textured, decorative look with genuine visual interest.  Coloured or pigmented concrete, mixed with an integral colourant before pouring, moves well beyond standard grey and can be matched to complement a house’s exterior or existing garden features. Stamped or patterned concrete, pressed with a textured mould before the surface fully cures, can even mimic the look of natural stone or block paving to a reasonable degree, though it’s worth being realistic that this rarely achieves quite the same convincing effect as genuine natural stone or high quality porcelain. These finishing options do add to the overall cost compared with a basic plain pour, which is worth factoring in if style is a genuine priority alongside concrete’s cost advantage for larger areas. Why Paved Slabs Have Genuine Advantages Paved slabs bring their own set of real benefits that poured concrete simply can’t match in the same way. The Practical Value of Slab-by-Slab Repair It’s worth expanding on the repair advantage specifically, since this is often the factor that tips a decision once homeowners genuinely think through the long term implications of each material. With paved slabs, a single cracked or chipped unit, whether from a dropped heavy object, frost damage, or simple wear over many years, can be individually lifted and replaced, with the new slab bedded in to match the surrounding level and finish. This is a relatively contained, affordable repair that doesn’t require disturbing anything beyond the immediate affected area. Poured concrete doesn’t offer this same option. A crack or area of damage in a poured slab generally requires breaking out a defined section, typically bounded by the nearest expansion joints if the original design included them, then repouring that section and allowing it to properly cure before it blends back into the surrounding surface.  This is inherently a bigger, messier, and more disruptive job than lifting a single paving slab, and colour matching a repaired concrete section to older, weathered surrounding concrete can also be genuinely difficult to achieve seamlessly, unlike swapping in a like for like replacement slab. The Main Downside of Poured Concrete: Cracking The genuine downside worth flagging with poured concrete is its tendency to crack over time, especially without properly designed expansion joints. Concrete naturally expands and contracts with temperature changes, and without expansion joints built into the design at appropriate intervals, this movement can cause visible cracking across the surface. This isn’t necessarily a sign of poor workmanship on every occasion, it’s a genuine characteristic of the material that needs to be properly planned for from the outset. Expansion joints, correctly positioned and sized, allow the concrete room to move without cracking, but skipping this step, or getting the spacing wrong, is a common cause of the cracking problems that give poured concrete patios a reputation for this specific issue. How

Jointing is one of those patio details that’s easy to overlook when planning a project, but it genuinely affects how well your patio performs and looks over the years. The two main options, resin based jointing compound and traditional kiln dried sand, aren’t simply a case of one being universally better than the other. The right choice really does depend on your slab type and your budget. At JPD Landscaping & Building Services, we’ve jointed patios across South East London for over 15 years, using both compound and sand depending on the project. This guide walks through exactly when each option makes sense, the practical differences between them, and a real example of how this decision plays out on an actual project. Key Differences Between Jointing Compound and Sand There’s no single answer that applies to every project here. Jointing compound and sand each suit different situations, and the right choice depends heavily on your slab type and budget. Slab Type and Jointing CompoundJointing Method: Jointing CompoundBest Suited To: Porcelain, large-format slabs, natural stone, high-traffic areas Slab Type and SandJointing Method: Kiln-dried sandBest Suited To: Traditional or rustic-style patios, budget-conscious projects LongevityJointing Compound: Longer-lasting, more durable over timeSand: Prone to washing out and weed growth over time What Is Jointing, and Why Does It Matter So Much? Before comparing the two materials directly, it’s worth being clear about what jointing actually does, since it’s easy to think of it as a purely cosmetic finishing touch rather than a functional part of the patio structure. The joint between each slab isn’t just filling a visual gap, it locks slabs together against lateral movement, stops water from working its way freely beneath the paving and into the bedding layer, and prevents debris, seeds, and organic matter from settling directly against the sub base underneath. A patio with poorly filled, eroded, or missing joints is genuinely more vulnerable to the kind of localised settling and drainage issues covered in our guide on patio drainage problems and fixes, since water finding an easy path down through open joints is one of several routes toward the sub base disturbance that eventually shows up as an isolated puddle or a rocking slab. Choosing the right jointing method, and applying it properly, is every bit as important to a patio’s long term performance as the bedding method used to lay the slabs themselves. When We Recommend Jointing Compound We specifically recommend jointing compound in a few common situations, and in our experience, these cover a genuinely wide range of typical patio projects. Across all three of these situations, the common thread is that compound performs better where precision, irregular shapes, or heavier use are involved. How Jointing Compound Actually Works It’s worth understanding briefly what makes resin based jointing compound perform so differently from sand, rather than treating the difference as simply a brand name versus a traditional material. Jointing compound typically combines fine aggregate with a resin binder, which cures to form a genuinely solid, semi flexible fill within the joint once applied and left to set. This cured material physically bonds to the sides of each slab within the joint, rather than simply sitting loosely in the gap the way sand does. This bonding is exactly why compound resists both washout during heavy rain and displacement from pressure washing far better than sand, and why weeds struggle to establish through it, since there’s no loose, organic friendly material for a seed to root into in the way there is with a sand filled gap. The trade off is that compound generally costs more per square metre than sand, and application technique matters more, since compound needs to be worked into the joint properly and any excess cleaned from the slab surface before it cures, whereas sand is more forgiving to apply even if it needs periodic topping up afterward. When We Recommend Kiln-Dried Sand Sand still has a genuine place in patio jointing, and we specifically recommend it for traditional or rustic-style patios where sand’s natural look actually suits the overall aesthetic the customer is going for. Some garden styles, particularly more traditional or countryside-inspired designs, benefit from the slightly less uniform, more natural appearance that sand jointing provides compared with the smoother, more consistent finish of a resin compound. This is a genuine aesthetic consideration, not just a budget compromise. For the right garden style, sand’s appearance is actually the preferred look, independent of any cost difference between the two options. Where Sand Genuinely Suits the Design Brief It’s worth expanding on this point, since it’s easy to read “we recommend sand for rustic patios” as simply code for “sand is the cheaper option customers settle for.” In practice, some homeowners specifically want the softer, more natural look sand jointing gives, particularly alongside riven or tumbled finish natural stone, cottage garden planting, or a period property where a very crisp, uniform compound joint would actually look somewhat at odds with the rest of the garden’s character. For these projects, recommending compound purely because it’s more durable would be missing the actual design brief. The honest answer is that sand remains a legitimate, deliberate choice in these situations, provided the homeowner understands and accepts the maintenance trade off that comes with it, covered in detail below. Durability and Common Problems Jointing compound offers noticeably better longevity than sand jointing, holding up well over an extended period without the common issues that affect sand over time. Sand jointing, by contrast, is prone to two common problems that tend to develop together over time: These two issues often appear together on the same patio, since a joint that’s lost some of its sand through erosion also becomes more vulnerable to a weed establishing in the resulting gap. How Pressure Washing Interacts With This Decision This is a good point to connect back to our dedicated guide on how to clean patio slabs, since jointing choice and cleaning technique are closely linked in practice. Sand jointing is

Keeping a patio clean is one of the simplest ways to protect its appearance and extend its lifespan, but it’s easy to cause more harm than good if the cleaning method isn’t right for the material or the jointing between slabs. Getting this right consistently makes the difference between a patio that stays looking good for years and one that develops problems from cleaning attempts that were a bit too aggressive. At JPD Landscaping & Building Services, we’ve cleaned and maintained patios across South East London for over 15 years. This guide covers exactly how to clean patio slabs properly, how often to do it, and the mistake that causes more jointing damage than any other cleaning error we see. Cleaning Patio Slabs Without Causing Damage To clean patio slabs safely, clear away loose debris first, then wash the surface using warm water and a mild detergent, which is safe for most slab types. Pressure washing is generally safe on most patio slabs, provided you use the right pressure setting and keep a reasonable distance from the surface. We recommend cleaning your patio twice a year, in spring and autumn, to stay ahead of dirt, algae, and grime before it builds up significantly. Steps for Cleaning Patio Slabs Safely Step 1: Clear the Patio of Debris Before applying any water or cleaning solution, sweep away leaves, dirt, and any loose debris sitting on the surface or trapped in the joints between slabs. This prevents you from simply pushing dirt around and stops organic material from staining the slabs once they become wet. Step 2: Apply a Mild Cleaning Solution For routine cleaning, warm water mixed with a mild detergent is genuinely sufficient for most patio slab types, whether that’s porcelain, concrete, or natural stone. There’s no need for harsh chemical cleaners for a standard seasonal clean, which are better reserved for tackling specific issues like stubborn algae or ground in staining. Step 3: Scrub Stubborn Areas if Needed For any particularly dirty or algae affected patches, a stiff outdoor brush combined with your cleaning solution should lift most residue without needing anything more aggressive. Work methodically across the patio rather than focusing all your effort on one small section. Step 4: Rinse or Pressure Wash Rinse the patio thoroughly with clean water, or use a pressure washer at an appropriate setting to remove any remaining dirt and cleaning solution. This is the step where care really matters, covered in detail below. Step 5: Let the Patio Dry Allow the patio to dry naturally before returning furniture or resuming heavy use. This also gives you a clear view of the finished result, letting you spot any areas that might need a second pass. Adjusting Your Cleaning Approach by Material While the general process above suits most patio materials well, it’s worth knowing a few material specific considerations. Porcelain’s non porous surface generally responds very well to a straightforward wash, rarely holding onto stains or algae as stubbornly as more porous materials, which is one of the practical advantages covered in our porcelain paving pros and cons guide. Natural stone, being somewhat more porous, can benefit from slightly more attention to algae prone, shaded areas specifically, and it’s worth checking whether your stone has been sealed, since some sealants recommend avoiding certain chemical cleaners that could affect the sealant layer itself. Concrete paving sits between the two, generally cleaning up well with the standard approach, though older or more porous concrete products can occasionally show more persistent staining in high traffic areas, sometimes benefiting from a slightly more thorough scrub during the seasonal clean. How Often Should You Clean Your Patio? We recommend cleaning your patio twice a year, in spring and autumn. This timing works well because it addresses two distinct challenges through the year: a spring clean removes the grime and organic buildup that accumulates over the wetter, colder months, while an autumn clean clears fallen leaves and debris before they have a chance to sit against the slabs and jointing over winter, where they’re more likely to encourage algae growth in damp, cold conditions. Season Why It Matters Spring Removes winter grime and checks for any developing issues Autumn Clears fallen leaves before they sit against slabs through winter Adjusting Cleaning Frequency for Shaded or High-Traffic Patios While twice yearly suits most gardens well, it’s worth knowing some patios genuinely benefit from a slightly more frequent approach. Particularly shaded, damp corners of a garden, similar to the conditions covered in our guide on the best patio slabs for a London garden, can develop algae and grime more quickly than a patio in a sunnier, more open position, sometimes warranting an additional clean during the year specifically targeted at those problem areas rather than the whole patio. Similarly, high traffic areas, such as a well used dining or entertaining zone, may benefit from more frequent spot cleaning between the two seasonal deep cleans, simply due to the additional wear and dirt these specific spots accumulate compared with less used sections of the same patio. Is It Safe to Pressure Wash Patio Slabs? Pressure washing is generally safe on most patio slabs, provided you use the correct pressure setting and maintain a sensible distance from the surface. Used properly, a pressure washer can clean a patio far more thoroughly and efficiently than manual scrubbing alone, particularly for lifting ground in dirt or algae from textured slab surfaces. The key word here is properly. Pressure washing done carelessly, at too high a setting or too close to the surface, causes genuine, avoidable damage, which brings us to the most common mistake we see. Choosing the Right Nozzle and Pressure Setting Getting genuinely good results from pressure washing without causing damage comes down largely to nozzle choice and pressure setting. A wider fan tip nozzle spreads the water jet’s force across a broader area, reducing the concentrated impact on any single point compared with a narrow, focused jet nozzle, which is considerably
