How much topsoil do I need?

Topsoil is a gardeners best friend. Not only does it provide your plants with all the nutrients they need to thrive, but it also supports root growth, maintains soil structure, retains moisture, and much more. In fact, it'sone of the key ingredients for a garden full of healthy, vibrant plants. 

There's a lot to consider when buying topsoil for your next project, including how much you'll need. The good news? Finding out is easier than you might think! 

At MB Wilkes, we've been mastering the art of all things garden-related for almost six decades. Below, we explain the steps you can take to identify the exact volume and depth of topsoil you need for your project.

What is topsoil?

Topsoil is the uppermost layer of soil covering the Earth's surface. As the layer where most of the biological activities of soil occur, it plays a crucial role in supporting plant growth and sustaining ecosystems.

Topsoil is a dynamic mixture of mineral particles (such as sand, silt, and clay), organic matter (decaying plant and animal material), water, and air. Healthy topsoil contains essential nutrients and microorganisms that plants require for their growth.

Topsoil is often confused with compost, but the two are actually very different - topsoil serves as a natural soil layer, while compost is a human-made product that enhances soil fertility through the addition of organic matter and beneficial microorganisms.

How to calculate how much topsoil you'll need

Determining the amount of topsoil you'll need is fairly straightforward. Here's a simple, step-by-step guide to help you in through the process:

  • Measure the length and width of the area you want to cover with topsoil. Make sure your measurements are in the same units (e.g. feet, metres).
  • Determine the depth of topsoil you need. Typical depths for different purposes are:
    Garden beds: 6 to 12 inches (15 to 30 cm)
    Lawn renovation: 2 to 4 inches (5 to 10 cm) 
    Filling or grading: Varies based on the project

We've explained more about how you can measure the required depth in the next section down.

  • Calculate the volume of topsoil needed using the formula: Length × Width × Depth = Volume. 

If your site has an area of 15m x 30m and needs a coverage of 200mm, for example, you should use this formula: 15 x 30 x 0.20 = 90m3.

Make sure your measurements are in the same units. For example, if you're using feet, your volume will be in cubic feet. If you're using metres, your volume will be in cubic metres.

  • Once you have the volume in cubic feet or metres, you can determine the number of bulk bags needed by dividing the total volume by the bag's capacity. Keep in mind that bulk bag sizes differ, so be sure to compare the contents of different bags to get the amount right.

If you instead need to calculate the necessary tonnage for buying loose topsoil, make sure to examine the product's bulk density. This density varies based on the specific type of topsoil and its composition.

How deep should topsoil be? 

The recommended depth of topsoil all depends on the type of plants you intend to grow, the climate, and the specific characteristics of your land. However, a good rule of thumb is to have a topsoil depth of around 6 to 12 inches (15 to 30 centimetres). This depth provides a sufficient amount of fertile soil for most plants' root systems to establish and thrive.

If the soil is shallow and poor quality, you may want to bring in the recommended amount of topsoil to provide the best growing conditions. To give your plants an even better shot at thriving, think about incorporating compost, organic matter, and nutrients to boost soil quality.

If your existing soil is already good quality, a thinner layer of new topsoil might do the trick, either to achieve the desired depth or to create a level surface with good texture. Don't forget that some plants, especially those with deep-rooted systems like trees, could use more topsoil depth to really flourish.

An Introduction to Scalpings
// Whether you're planning to construct a residential driveway or a large-scale commercial build, choosing the right materials is key to a successful project. There are thousands of different materials you can choose from, and it's not always easy knowing which will work best for your requirements. Scapings are one such option. These small, rough stones are ideal for creating level sub-bases for driveways, paths, and patios, making them an excellent choice for a wide variety of building projects. MB Wilkes is the leading supplier of 40mm scalpings in Dorset. In this guide, we explain where scalpings come from, why they’re useful, and how much you will need for your build. Already know you need scalpings for your project? Buy high-quality scalpings online today!   What are scalpings? Scalpings are essentially quarry waste. They are clay-contaminated stones that are removed when larger rocks are screened for quality. Whilst the concept of 'quarry waste' may not sound appealing, scalpings are actually the perfect material for evening out foundations - they are durable, versatile, and plentiful. Their low cost can also help you save significant money on your project.   What are scalpings used for? Scalpings are largely used as a sub-base material during the construction of car parks, driveways, pathways, and foundations for buildings. They are a cheaper alternative to Type 1 aggregates. When used in construction, scalpings work well to fill gaps within a bumpy foundation and provide an ideal base for paving and slabs. What sizes do scalpings come in? Scalpings are available in a range of sizes, including 40mm, 75mm and 100mm. The size of scalpings refers to the size of the holes in the 'sieve' when they are separated from larger rocks at the quarry. The most popular choice is 40mm, as this is the size that best suits the majority of projects, both commercial and residential.   What amount of scalpings will I need? The amount of scalpings you'll need is dependent on the size of your project. On average, 1 tonne of scalpings will cover 11.4m2 at 50mm thick. If you’re not sure how much you’ll need, you can use our online calculator before buying.   Where can I buy scalpings in bulk? At MB Wilkes, we stock fantastic quality scalpings for sale at low prices. We deliver to the entirety of Poole, Bournemouth, and Dorset, and can transport your scalpings in either bulk bags or loose. No matter the type or scale of your project, we’ll get you what you need without hassle. Buy scalpings online today!

How to choose the right sports sand for your playing surface
If you’ve ever tried to hit a golf ball out of a bunker or hopped, skipped, and jumped into a long-jump pit, you might have noticed the sand under your feet feels different from regular sand. That’s because it is - it’s sand that’s been specifically designed for use in sports and athletics. While it may make the inside of your trainers a bit gritty, sports sand serves two important purposes: it improves player performance, and it keeps surfaces in good playing condition. The specialists at M B Wilkes are experts in all types of sand, soil, and gravel. Let us walk you through everything there is to know about sports sand, so you can rest easy knowing that your club’s playing surface is in tip-top shape.   What makes sports sand different? Because it needs to provide an even, safe surface for sports to be played on, sports sand has key differences from the sand you find on the beach or on a construction site. Most sports sand goes through a special ‘cleaning’ process that removes clay, silt, dust, and other impurities. This creates a fine, smooth finish that’s perfect for recreational use. To provide you with a safe surface on which to play your sport, sports sand usually has: Smaller, finer grains for a softer surface Impurities removed by washing Air-filled porosity to provide excellent aeration and drainage Consistent grading These qualities make the sand super soft to walk on and quick to dry. It also won’t get stuck on your legs or feet as you run over it.   What makes high-quality sports sand? Not all sand is the same. Different types of sand have different sized grains, mixes, and consistencies, which make certain sands more suited for certain uses than others. Selecting the correct grade of sand for your playing surface is vitally important. The ‘grade’ of a sand refers to the size of each individual particle, ranging from the smallest and ‘finest’ to largest and ‘sharpest’. Each type has distinctly different qualities that are useful in different applications. You’ll find finer sand has less structure and more malleability, while sharp sand is strong but prone to cracks and lesions. Sport sand shouldn’t be either too sharp or too fine – you’ll find that a quality, washed sports sand will be between grades 30 and 45, placing it somewhere in the middle. Sand aids in the process of drainage, with each grade of sand having a different effect on the playing surface. For example, fine sand effectively seals up the playing surface if spread over the top layer, meaning you’ll struggle to get your pitch to drain. Sharp sands will destabilise the surface over time, negatively impacting the general makeup of the soil. This makes it even more important to remember the 30 to 45 grading. In order to get the best results out of your sand spreading, there are steps you should take to make sure you don’t cause unneeded damage to the grass. Post-match, it is recommended that you divot the pitch with a fork, as this aerates the surface after being compacted by players. It also allows you to spread the sand into the top layer of surface soil. If you’re looking for high-quality sand to use for sporting and recreation, make sure the sand is: Low maintenance, so it’s easy to lay and look after Naturally sourced, as sand from natural sources has fewer contaminants and is therefore of higher quality Washed clean of any unwanted particles for a smooth finish. Made of durable aggregate, so it can withstand even the toughest of sports.   Which sports sand do I need? The exact type of sand you should choose depends on what you’ll be using it for:   Sports sand for recreation Our imported washed sand is 0-2mm and ideal for surface dressing sports fields, rugby and cricket turfs, golf bunkers, bowling greens, goal mouths, and much more.   Specialist sports sand from M B Wilkes At M B Wilkes, Dorset’s leading supplier of sand and other landscaping supplies, we have a range of top-quality sports sands for you to choose from. Our naturally-sourced sports sand will create a soft, all-weather playing surface your sports club can rely on. Browse our range of sands to find the right type of you.

Why should you invest in recycled aggregate?
Throwing good money at materials that end up in landfill? There's a smarter way to build. So, why should you buy recycled aggregates rather than always reaching for brand-new materials? Whether you're tackling a driveway, laying drainage, or working on a larger landscaping project, the costs and environmental impact can quickly add up, and sourcing the right materials at the right price isn't always straightforward. Recycled aggregates offer a practical, cost-effective solution that more and more homeowners and contractors are choosing. At MB Wilkes, we supply a fantastic range of recycled aggregates in Dorset directly from our family-owned quarry, so you get quality materials and honest advice all in one place. Read on to find out why recycled aggregate could be the ideal choice for your next project. What Can Recycled Aggregates Actually Be Used For? Recycled aggregates are far more versatile than many people realise, making them a brilliant choice for a wide range of domestic and commercial projects across Dorset and beyond. Driveways and Pathways Recycled aggregate is a popular choice for driveways and paths, offering a solid, hard-wearing surface that handles regular foot and vehicle traffic with ease. It compacts well, drains effectively, and gives a neat, practical finish. It's a cost-effective alternative to virgin materials without any noticeable drop in performance. Drainage Projects One of the most common uses for recycled aggregate is drainage. Whether you're installing a soakaway, improving surface water management, or working on a larger drainage scheme, recycled material performs brilliantly. Its angular, irregular texture helps water filter through efficiently, reducing the risk of waterlogging in gardens, driveways, and construction sites. Sub-Base and Groundwork Before any surface goes down, you need a reliable foundation beneath it. Recycled aggregate is widely used as a sub-base material for patios, driveways, and construction projects because it compacts firmly and provides excellent load-bearing support. It's a practical, dependable option that gets the groundwork right from the start. Landscaping and Garden Projects Recycled aggregate isn't just for heavy-duty construction work. It works wonderfully in garden landscaping too, from filling raised beds to creating informal paths and borders. If you're looking for a low-maintenance, budget-friendly material that still looks tidy and well-considered, recycled aggregate is well worth exploring for your next outdoor project. The Environmental Impact of Using Recycled Aggregates Sustainability is something we all think about a little more these days, and the materials you choose for your project can make a real difference. Recycled aggregates are produced by reprocessing construction and demolition waste that would otherwise end up in landfill, which is a fantastic way to give existing materials a second life. By choosing recycled over virgin aggregate, you're also helping to reduce the demand for new quarrying activity, which in turn lowers the energy used in extraction and transportation. Less quarrying means less disruption to the natural landscape too. For contractors and homeowners alike, it's a practical way to reduce your project's carbon footprint without sacrificing performance or quality. At MB Wilkes, we're proud to offer recycled aggregate products that support a more sustainable approach to building and landscaping right across Dorset. SuDS Compliance Sustainable Drainage Systems, or SuDS, are increasingly required in new builds and renovation projects, and recycled aggregate plays a useful role in meeting those requirements. Its natural permeability allows surface water to drain through gradually, reducing runoff and the risk of localised flooding. For anyone navigating planning requirements around drainage, it's a genuinely practical material choice. Reduced Haulage Impact Sourcing your recycled aggregates locally makes a difference beyond just convenience. Shorter delivery distances mean fewer lorry movements on local roads, lower fuel consumption, and a reduced carbon footprint compared to importing virgin materials from further afield. Because we supply directly from our Dorset quarry, so you benefit from efficient, local delivery that keeps unnecessary haulage to a minimum. Additional Benefits of Buying Recycled Aggregates In addition to being a sustainable choice, there are other benefits of recycled aggregates that make it easy to see why so many homeowners and contractors are choosing them as their go-to material for all manner of projects. Significant Cost Savings As you might expect, the cost of buying recycled aggregate is more affordable than using brand new. It’s far less expensive to use recycled aggregate and if you buy local, you’re also saving money on transportation costs. You can save a lot of money by investing in recycled aggregate and there isn’t too much of a noticeable difference between buying new and buying second-hand. No Compromise on Performance A common concern is whether recycled aggregate is as reliable as new material. In most applications, including sub-base, drainage, and pathways, it absolutely is. Recycled aggregate is robust, hard-wearing, and fully capable of meeting the demands of everyday use. You get the performance you need at a price that makes far more sense for your budget. Readily Available and Quick to Deliver Sourcing materials shouldn't slow your project down. At MB Wilkes, we hold good stock levels of recycled aggregate, so you're not left waiting around. With our fully equipped fleet of tipper trucks and grab lorries covering Poole, Bournemouth, and across Dorset, we can efficiently deliver materials to you, keeping your project moving at a steady pace.

How Much Sub-Base Do I Need for My Project?
Ever stood in your driveway with a tape measure, wondering if you're about to order way too much material or nowhere near enough? If the first question that comes to mind is “how much sub-base do I need?”, then hopefully this blog will have you covered. We're going to answer that question with a simple, reliable formula that takes the uncertainty out of ordering. And you can trust that we know what we’re talking about. At MB Wilkes, we've been supplying sub-base materials across the UK for over 60 years, offering both delivery and quarry collection so you can get exactly what you need, when you need it. Understanding Sub-Base and Its Uses Sub-base is the unsung hero of any solid construction project. It's the compacted foundation layer that sits beneath your finished surface, distributing weight evenly and preventing your driveway, patio, or pathway from cracking, sinking, or shifting over time. Skipping the use of sub-base materials can lead even the most beautifully laid paving to eventually fail. We recommend it for driveways, patios, garden paths, shed bases, and any foundation work where long-term stability matters, making it an essential first step in groundwork that simply can't be skipped. Common Types of Sub-Base Material When you're choosing between sub-base aggregates, the two main options you'll encounter are MOT Type 1 and MOT Type 3, each designed for different applications depending on the load requirements of your project. MOT Type 1 consists of crushed concrete or limestone, like our Type 1 Mendip, that's been carefully graded to create a dense, stable base when compacted. It's the workhorse of sub-base materials, ideal for driveways, heavy-duty patios, and any area that'll bear significant weight from vehicles or foot traffic. The angular particles lock together beautifully under compaction, creating a solid foundation that won't shift. MOT Type 3 (often called scalpings), such as Type 3 Limestone, is a finer material made up of smaller crushed stone and dust. While it still provides excellent compaction, it's typically used for lighter applications like footpaths, shed bases, or as a blinding layer over MOT Type 1. It's also brilliant for filling gaps and levelling surfaces before your final paving goes down. How Much Sub-Base Do You Need – The Simple Formula So, onto the question of “how much sub-base do I need for type 1?” The sub-base calculation couldn't be more straightforward. Take your area in square metres Multiply by your depth in millimetres divided by 1,000 Multiply that result by 2.2 to get the tonnes you'll need Equation: Area (m²) × Depth (mm ÷ 1,000) × 2.2 = Tonnes That 2.2 figure represents the density of compacted sub-base, converting your volume into actual weight for ordering purposes. Bear in mind that materials typically compress by 25–30% when a plate compactor is used. It is standard industry practice to add 5–10% extra to the final tonnage to account for uneven subgrades or spillage during the work. Alternatively, you might be asking “how much sub-base do I need for type 3?”. In short, the calculation remains the same, you simply adjust the density from 2.2 down to 1-8 – 2. Step-by-Step Calculation Example Let's work through how much sub-base you’ll need for a typical driveway measuring 20m² at 100mm depth. First, we calculate 20 × (100 ÷ 1,000) × 2.2, which gives us 20 × 0.1 × 2.2. That works out to 4.4 tonnes. Since our bulk bags typically hold around 850kg each, you'd need approximately seven bags to cover this area comfortably, allowing for a bit of overage during compaction and levelling and some wastage. Recommended Depths for Different Projects Understanding how much sub-base you need depends entirely on what you're building and the load it'll carry. Different applications require different foundation depths to perform properly over time. Driveways and Vehicle Access: Aim for a driveway sub-base depth of 150-200mm to support the weight of cars and regular traffic without settling or rutting. Patios and Footpaths: A patio sub-base depth of 75-100mm provides sufficient support for pedestrian use whilst keeping material costs reasonable. Shed Bases: Between 75-100mm works well for garden buildings and lighter structures that won't experience heavy loading. Heavy-Duty Applications: For commercial drives or areas with frequent heavy vehicle access, go for 200mm or more to ensure long-term durability. Ordering Your Sub-Base from MB Wilkes If you’re asking yourself, “how much sub-base do I need?” and you’re still unsure, we’ll be happy to advise you. Either way, ordering from us couldn't be easier. We offer bulk bag (850kg) deliveries for smaller residential projects like patios and paths, which are perfect when you need precise quantities and easy handling. For larger builds such as driveways or extensive groundwork, loose loads delivered by the tonne offer better value and faster coverage, letting you tackle substantial areas without constantly restocking materials. Our Sub-Base Material Options We stock a comprehensive range of sub-base materials to suit every application. Our MOT Type 1 limestone and crushed concrete options provide that rock-solid foundation for driveways and high-traffic areas, compacting down beautifully to create a level, stable base. For lighter projects, our MOT Type 3 scalpings offer excellent value while still delivering the compaction you need for paths and shed bases. Each material is quality-checked and ready to perform exactly as it should, giving you confidence in your groundwork from the very first layer. Delivery and Collection We deliver across our coverage area with flexible scheduling to match your project timeline. Minimum order quantities apply for delivery, so do give us a ring to discuss your specific requirements. If you're a trade customer or need materials immediately, you're welcome to collect directly from our quarry using our weighbridge service, which means you can load up and get straight back to site without waiting for delivery slots. Tips for Ordering the Right Amount Even with an accurate calculation, there are a few practical considerations that'll help you order the perfect quantity of sub-base aggregates for your project without ending up short or with too much leftover: Add 5-10% Extra: Compaction always uses more material than you'd expect, and uneven ground or small wastage during installation means a buffer ensures you won't run out mid-project. Round Up to Full Bags: If your driveway sub-base depth calculation gives you 4.4 tonnes, order five bags rather than four to account for variations in coverage. Consider Access: Tighter spots or areas with awkward levels might require more material for proper compaction, so factor in your site conditions. Account for Edging: Your patio sub-base depth extends slightly beyond the finished surface, so measure generously rather than cutting it fine. Get Your Sub-Base Delivered Today Now you've got the formula and know exactly what you need, it's time to get your project moving. Calculate your requirements, then give us a call on 01258 857465 or fill in our contact form to place your order.

How can soils and aggregates stop flooding?
If you're wondering how to stop garden flooding, whether you're a keen gardener or managing farmland, we've got a straightforward seven-step plan that works brilliantly. British weather can be unpredictable, and those heavy downpours are inevitable, but improving your soil structure makes all the difference. At MB Wilkes, we know a thing or two about soils and aggregates. Following these seven simple steps will help reduce flooding risks and keep your outdoor space in top condition, so you can focus on what matters most: enjoying your garden or growing successful crops year after year. 1. Minimise Tillage So, how does soil prevent floods? It all starts with tillage. When you minimise soil disturbance, you're helping it develop better structure and aggregation, which means it acts like a natural sponge during heavy rainfall. Well-structured soil absorbs and retains water brilliantly rather than letting it run off and cause flooding. Reduced tillage also preserves organic matter, which is fantastic for improving water-holding capacity and overall soil health. The more organic matter your soil contains, the more water it can store, keeping your garden or farmland protected during those inevitable British downpours. 2. Limit Farm Traffic If you're wondering how to stop a clay garden flooding, timing your farm traffic makes a real difference. Heavy machinery like tractors and combines compacts the soil, reducing pore space and making water infiltration much harder. Compacted soil behaves like a hard surface, increasing runoff during rainfall and worsening flooding risks. By limiting traffic to dry periods and avoiding movement when conditions are wet, you'll maintain better soil structure that absorbs water more effectively. It's a straightforward step that protects your soil's natural drainage capacity and keeps your land in better condition year-round. 3. Manage Drainage Proper drainage management is essential for preventing flooding in both rural and urban settings. A well-designed drainage system redirects water flow away from vulnerable areas that are prone to waterlogging, protecting your soil and plants from excess moisture. Whether you're managing a large farm or a residential garden, effective drainage prevents water from accumulating in problem spots and causing damage. By channelling water to appropriate areas, you maintain healthier soil conditions and reduce the risk of standing water that can harm crops, plants, and landscape features during periods of heavy rainfall. 4. Use Cover Crops, Green Manures and Mulches Knowing how to stop garden flooding often comes down to what you plant between your main crops. Cover crops, green manures, and mulches are brilliant for improving soil structure and reducing water runoff. As they decompose, they add valuable organic matter that helps soil absorb more water, preventing surface flooding during heavy rain. These protective layers also shield bare soil from rainfall impact, minimising crusting and allowing better water infiltration. Here's what they offer: Enhanced soil structure and water retention Reduced surface runoff and erosion Improved organic matter content Better water penetration during downpours 5. Use Grass Leys to Improve Organic Matter Grass leys (fields planted with grasses and legumes) are fantastic for enriching soil and great if you’re wondering how to stop garden flooding naturally. As these plants decompose, they add organic matter that creates better soil structure capable of holding more water during heavy rainfall. The extensive root networks they develop promote soil aggregation while reducing compaction, leading to improved water infiltration and storage. Well-structured soil equipped with this organic boost handles excess water far more effectively, significantly reducing surface flooding risks. It's a natural, sustainable approach that benefits both your soil health and flood prevention efforts. 6. Use Plants with Large Roots Another trick if you’re wondering how to prevent your garden from flooding is to use plants with large roots. Large roots create natural channels within the soil, improving structure by increasing pore space and reducing compaction. This enhanced structure allows better water infiltration, meaning your soil holds more water instead of letting it run off and cause flooding. Deep-rooted plants also absorb water from lower soil layers, preventing surface accumulation while helping recharge groundwater. During periods of heavy rainfall, these plants actively remove water from the surface, offering natural flood protection that works alongside the soil's improved drainage capacity. 7. Try Agroforestry Agroforestry combines trees or woody shrubs with crops or livestock on the same land, creating a sustainable system that's brilliant for those wondering how to stop garden flooding. The tree roots work similarly to large-rooted plants, creating channels that improve soil aggregation and increase water infiltration. These established root systems enhance soil structure while the trees themselves absorb significant amounts of water, which is particularly helpful during prolonged wet periods. It's an integrated approach that benefits your land in multiple ways, from improved drainage and reduced flooding risks to better soil health and increased biodiversity across your property. Bonus Tip On the subject of how to stop surface water flooding in problem areas, there’s one more step you can take, and that’s to use specific aggregates. Drainage aggregates like our Cerney Gravel, crushed rock (think Basalt Chippings), or porous materials like our Type 3 Limestone create pathways for water to infiltrate quickly, reducing surface runoff and standing water accumulation. We stock quality drainage materials that offer: Rapid water infiltration through porous structure Temporary storage during heavy rainfall Controlled, gradual water release Prevention of flash flooding and uncontrolled runoff These aggregates are a practical solution for gardens, driveways, and farmland prone to waterlogging.   Need Drainage Solutions?
