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.

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?

The ultimate guide to choosing gravel and shingle
How to Choose and Plan the Perfect Gravel Driveway Are you planning a gravel driveway but feeling overwhelmed by the choices available? You're not alone in wondering how to choose and plan the perfect gravel driveway that combines functionality with aesthetic appeal. At MB Wilkes, we've been helping homeowners navigate these decisions for over 60 years as a family-owned quarry. Our comprehensive guide will walk you through everything from material selection to design considerations, ensuring your new driveway becomes a beautiful and practical addition to your home. With our consultative approach and National Trust-approved gravel products, we'll help you deliver a driveway that perfectly suits your needs and budget. Understanding Gravel and Shingle Types Now that you're ready to explore your options, let's examine the difference between gravel and shingle and understand the various types available. Gravel particles typically start at around 5mm, whilst anything smaller is classified as sand. However, our shingle range begins at 2mm-6mm, offering you greater flexibility for different applications. Our signature light golden flint shingle showcases beautiful brown and yellow tones, making it perfect for creating warm, welcoming driveways. The difference between shingle and gravel lies primarily in size and application, with our range extending up to 40mm varieties ideal for drainage and soakaways. These natural materials come in numerous shapes, sizes, and colours, giving you tremendous versatility for your project. Different types of gravel and shingle serve specific purposes: smaller particles work brilliantly for decorative areas, whilst larger stones excel in functional drainage applications. For a deeper dive into selecting the ideal material, we've covered the pros and cons of various options in our comprehensive gravel guide, helping you understand which type suits your specific requirements. Choosing the Right Material for Your Project Here we're going to focus on matching the perfect material to your unique situation. When considering gravel vs shingle for your project, think about your space requirements and intended use. Shingle gardens often benefit from finer particles that create smooth, walkable surfaces, whilst larger gravel works excellently for vehicular access. Colour coordination plays a crucial role in your material selection. Neutral driveway materials like grey, beige, or white complement most home exteriors beautifully, blending seamlessly with existing architecture. However, if you're seeking to create a statement feature, consider our coloured options or even combine different materials for added visual interest. Quality considerations shouldn't be overlooked when making your choice. Our National Trust approval demonstrates our commitment to supplying materials that meet the highest standards for both durability and aesthetic appeal. The decision when comparing gravel vs shingle ultimately depends on your specific needs: shingle offers a more refined appearance perfect for formal settings, whilst gravel provides robust functionality for high-traffic areas. Both options deliver excellent long-term value when selected appropriately for your project's requirements. Design and Planning Considerations To learn more about creating the perfect layout, let's explore the essential planning elements for your gravel driveway. Planning a gravel driveway requires careful consideration of several key factors that will determine both its functionality and visual appeal. Consider these crucial design elements: Space and Shape Assessment: Decide between curved pathways for a softer, more natural appearance or clean, straight lines for contemporary appeal Multi-Car Requirements: Calculate width needs for side-by-side parking to eliminate daily car shuffling Visual Integration: Choose whether your driveway should serve as a focal point or blend harmoniously with surrounding landscaping Accessibility Considerations: Ensure adequate turning circles and comfortable gradients for all users Those wanting a permeable driveway design should also account for proper drainage requirements, particularly if your property experiences heavy rainfall. The natural permeability of gravel makes it an excellent choice for sustainable water management, reducing surface runoff whilst maintaining an attractive appearance. Balancing functionality with aesthetic appeal often means considering how your driveway connects with existing garden features, pathways, and architectural elements. In fact, we even have a blog that discusses how to build the perfect gravel garden – definitely worth a read. This thoughtful approach to planning a gravel driveway ensures your investment enhances your property's overall value and kerb appeal. Technical Requirements and Installation Tips Moving on to the practical aspects, proper gravel installation requires attention to specific technical details that ensure longevity and performance. Slope limitations are particularly important: we recommend avoiding loose gravel on gradients exceeding 1:10, as steeper inclines can lead to material displacement and maintenance issues. For gentle slopes that fall within acceptable limits, polythene hexagon mesh provides an excellent solution. This mesh sits approximately 40mm beneath the gravel surface, creating stability whilst maintaining the natural appearance of your driveway. Proper ground preparation forms the foundation of successful gravel installation, requiring adequate excavation, base material application, and compaction. The pallet-dragging method creates that perfectly raked finish, redistributing gravel evenly across the surface. Regular maintenance also prevents weed growth and maintains the professional appearance that makes gravel such an attractive, low-maintenance option for busy homeowners seeking both beauty and practicality. Making Your Final Decision As you approach your final choice, several factors will help you determine the best solution for your specific situation. Our consultative approach means we'll work closely with you to match products perfectly with your project requirements, ensuring optimal results. Key decision factors include: Budget Considerations: We offer cost-effective options without compromising on quality, helping you achieve excellent value Long-Term Maintenance: Gravel driveways provide brilliant low-maintenance solutions compared to alternative materials Expert Guidance: Our 60+ years of experience as one of the UK's leading landscaping suppliers ensures you receive knowledgeable recommendations The gravel vs shingle decision often comes down to your specific aesthetic preferences and functional requirements. With an extensive range including countless types of gravel and shingle, you’re assured of exceptional performance that meets your preferences and a driveway that’s properly specified and installed.

Choosing the Best Gravel for Your Driveway
A new driveway is one of those jobs where the finish only tells half the story. What lies beneath matters just as much, and getting it wrong means shifting stone, pooling water and a surface that looks tired within a year or two. If you're weighing up options, choosing the best gravel for your driveway comes down to understanding what each layer needs to do, not just which stone looks nicest on top. That's what we'll walk through here, starting with the fundamentals that make any gravel driveway perform well over time. What Makes a Good Driveway Gravel Work Hard A driveway has to support the weight of vehicles, stay exactly where it's put, drain water away quickly, and resist rutting and potholes forming under regular use. Choosing the best gravel for your driveway means picking material suited to those four jobs, not just whatever looks good. This is why angular crushed stone driveway material is usually the better structural choice over smooth, rounded gravel. The jagged edges lock together under pressure, creating a firm surface that holds its shape. Rounded stone, by contrast, tends to roll and shift, which is fine underfoot in a garden but less forgiving under a car. Drainage plays an equally important role. A slight fall or crown across the surface lets water run off rather than sit, since standing water is what accelerates erosion, potholes and stones working loose over time. Building the Right Layers for Your Driveway A gravel driveway isn't one material laid straight onto soil. It's built in layers, each doing a different job, and getting this build right is what separates a driveway that lasts decades from one that needs constant patching. Gravel for driveways typically works best across three stages: Base Layer: Large angular crushed stone or quarry-type material, usually a gravel driveway sub-base MOT Type 1 installation, creates a stable foundation and helps water drain rather than collect. Middle Layer: medium-sized crushed stone fills voids between the coarse base and the finer surface, adding stability and helping the whole structure lock together. Top Layer: Smaller crushed stone, pea gravel or decorative aggregates finish the surface, giving you the look and texture you actually walk and drive on. Each layer supports the one above it, so skipping a stage or skimping on depth tends to show up as problems later, not immediately. How Deep Should Driveway Gravel Be, and What Does It Cost? How deep should driveway gravel be? This depends on which layer you're looking at. As a general guide, the base layer needs the most depth to spread vehicle weight properly, the middle layer is thinner, and the top layer only needs enough coverage to look finished and stay put underfoot. Skimping on any one layer to save material is usually a false economy, since a shallow base is far more likely to rut or shift under regular traffic. Gravel driveway cost per m2 varies depending on the stone type, how many layers your project needs, and the size of the area being covered. Decorative aggregates and pea gravel finishes tend to sit at different price points to standard crushed stone, so it's worth thinking about budget alongside performance when choosing the best gravel for your driveway. A driveway built with the right depth from the outset costs less over its lifetime than one that needs regular topping up or repair. Pea Gravel vs Crushed Stone: Which Wins for Durability? This is often where the pea gravel driveway pros and cons come into sharpest focus. Pea gravel looks attractive, feels pleasant underfoot, and works well as a decorative top layer. Its smooth, rounded shape is exactly what makes it less suited to heavy use though, since round stones move more easily under tyres than angular ones. For most durable driveway gravel, angular crushed stone or granite chippings tend to win out, particularly on slopes or driveways with frequent vehicle use. The interlocking shape resists rolling and stays where it's laid, which matters most if you're after the best gravel for driveway that won't move. If you like the look of pea gravel, it doesn't have to be ruled out entirely. Using it as a thin decorative top layer over a properly built angular base gives you the appearance you want, without asking a structural layer to do a job it isn't shaped for. Getting the Installation Right The material you choose only performs as well as the installation underneath it. Most driveways need enough excavated depth to accommodate multiple layers, since squeezing a full build into a shallow dig compromises drainage and load bearing from day one. A geotextile or landscaping membrane, laid before any crushed stone driveway material goes down, stops the gravel mixing with the soil beneath and helps reduce weed growth pushing through over time. It's a small step that makes a noticeable difference to how long the surface performs well. Edging is worth including too. Whether it's a simple timber or metal border, edging keeps gravel contained rather than spreading onto lawns or paths, and it gives the finished driveway a cleaner, more defined edge. Granite chippings for driveway finishes in particular benefit from solid edging, since their angular shape can otherwise migrate outwards with regular use. Keeping Your Gravel Driveway Looking Its Best A gravel driveway isn't maintenance-free, but the upkeep it needs is straightforward once you know what to look for. Keeping on top of a few simple tasks protects the investment you've made and keeps gravel for driveways looking sharp for years: Rake regularly to keep the surface evenly distributed and maintain that slight crown that helps water run off rather than pool. Top up thinning areas where material has spread or compacted over time, particularly near entrances and turning points. Check drainage periodically, since blocked or poor drainage is what leads to erosion and potholes if left unaddressed. Manage weeds even where a membrane is in place, as occasional growth can still appear and is easiest to deal with early. Gravel driveway cost per m2 for materials is only part of the picture. Factoring in occasional maintenance from the start, rather than treating it as an afterthought, is what keeps a gravel driveway working in your favour long term. Ready to Get the Right Gravel Down? We've been supplying sand and gravel from our Dorset quarry for over 60 years, and we know what performs well on driveways across the South Coast.

5 Types of Aggregate and Their Uses
Aggregate is one of those materials most people have used without thinking too hard about what it actually is. Whether it's gravel on a driveway, sand in a concrete mix, or chippings around a planted border, it's the backbone of more projects than most people realise. The problem is that aggregate covers a lot of ground, and picking the wrong type can mean poor drainage, a mix that doesn't set, or a finish that looks wrong. At MB Wilkes, we've been supplying aggregates from our Dorset quarry for over 60 years. In this blog, we showcase five of the most used types, so you can decide which one is right for your project. And you can explore many more options on our website. Five Aggregates Worth Knowing About Each of the aggregates below has its own set of properties and best-fit applications, so here's a practical breakdown to help you choose the right material for your project. Slate Slate is one of the most versatile aggregates we stock, equally at home as a decorative mulch around planted borders and as a practical drainage material. Its angular shape allows water to pass through freely, which makes it a sensible choice anywhere you need both good drainage and a clean, attractive finish. We supply slate in three colours and two sizes, so there's a combination to suit most projects: Black Slate 20mm and 40mm Blue Slate 20mm and 40mm Plum Slate 40mm Sand Technically classified as a fine aggregate, sand behaves differently to coarser materials but is no less essential to a well-executed project. It is commonly used as a bedding material for paving and block paving, as well as in concrete mixes and render. Sharp sand and building sand serve different purposes, so the right type will depend on your application. If you're not sure which grade suits your project, our team can point you in the right direction. Limestone Limestone is a versatile aggregate used in a variety of construction and landscaping applications. It is commonly used as a sub-base material for driveways and pathways, as well as in drainage projects. Its durability and availability in different grades make it a practical choice for both residential and commercial projects. Granite Chippings Granite chippings are one of the toughest aggregates available, making them a strong choice for driveways and areas that take regular heavy traffic. The material compacts well and holds its shape under load, which means it tends to stay put rather than migrating to the edges over time. Granite also comes in a variety of shades, from grey to pink, so the practical benefits don't have to come at the expense of appearance. All In Ballast All In Ballast is a mixed aggregate containing a blend of sand and gravel in varying particle sizes. It is most commonly used in concrete mixes, where the combination of fine and coarse material helps produce a strong, workable mix. It also works well as a general fill and is a cost-effective option for groundwork and construction projects where a precise, single-grade aggregate isn't required. Why Choose MB Wilkes for Your Aggregates? We've been supplying sand, gravel and aggregates from our quarry in Dorset for over 60 years.
