Top Soil

What is screened topsoil and why do I need it?

Screened topsoil has been passed through a mechanical mesh to remove large stones, roots, and debris. This process ensures a consistent texture that is easy to work with and provides the best environment for root growth.

For projects in Essex, London & Kent, using screened soil is essential for a professional finish, especially when laying turf or planting delicate shrubs.

Is your top soil screened?

Yes, our top soil is fully screened to remove large stones and debris, ensuring it is ready for landscaping or turfing.

How do I know which grade of soil I need?

The grade depends on your specific project goals:

BS3882 Multi-purpose: The industry standard for most construction and landscaping projects. It is nutrient-balanced and perfect for general planting.

Economy Soil: Best for raising levels or filling large voids where high nutrient content isn’t the primary concern.

Premium/Enriched: Ideal for flower beds or vegetable patches where maximum organic matter is required.

How much topsoil should I order?

To calculate your requirements, multiply the area (length x width) by the desired depth. For laying new turf, we generally recommend a depth of at least 100mm to 150mm.

One tonne of our topsoil typically covers about 10 to 12 square metres at a depth of 50mm. If your site has uneven levels, our team can help you estimate a bulk load for your Essex, London & Kent delivery to ensure full coverage.

Can you deliver to sites with restricted access?

Yes. Navigating tight London streets and restricted site entrances is our specialty. Our 8-wheel tippers are operated by highly experienced drivers who are used to working in urban environments.

To make the delivery as smooth as possible, we recommend using timber laths to mark out exactly where you want the pile dropped. This ensures our drivers can tip accurately and safely without interfering with other site operations.

Is your soil safe for residential and school projects?

Absolutely. We take soil quality seriously. Our topsoil is sourced responsibly and is tested to ensure it is free from contaminants and harmful pathogens.

This makes our topsoil service the preferred choice for schools, public parks, and residential developments across the Home Counties where safety and environmental compliance are non-negotiable.

Crushed Concrete

What is the difference between Primary and Recycled MOT Type 1?

Primary is freshly quarried stone, while Recycled is high-quality crushed material; both meet Department of Transport specifications.

What is the difference between 6F2 and MOT Type 1 Crushed Concrete?

6F2 (or 6F5) is a coarser, “as-crushed” product typically ranging from 75mm down to dust. It is best used for bulk fill and temporary haul roads.

MOT Type 1 Crushed Concrete is screened more finely (40mm down to dust) to meet Ministry of Transport specifications. It is a higher-grade recycled product used for permanent sub-bases under roads and building slabs where tighter compaction is required.

Is crushed concrete as strong as primary stone?

Yes, for the vast majority of sub-base applications, recycled crushed concrete is an excellent substitute for primary limestone or granite.

It compacts exceptionally well because the angular shapes of the crushed stone interlock tightly. This makes it the preferred choice for piling mats and heavy-duty foundations across Essex, London & Kent.

Is it environmentally friendly?

Absolutely. Choosing crushed concrete London reduces the demand for virgin quarried aggregates and prevents thousands of tonnes of demolition waste from going to landfill.

By using our recycled products, your project can gain valuable “green” credits and meet the sustainability targets often required by local councils in the London area.

How much should I order?

Because crushed concrete is often used for deeper fills than topsoil or Type 1, the tonnage can add up quickly.

As a rough guide, 1 tonne will cover approximately 4 to 5 square metres at a 100mm depth. However, because it is often used for capping or heavy fill, we suggest speaking to our team about your specific site levels in Essex, London & Kent for a more accurate estimate.

How do I prepare the site for delivery?

To ensure our tippers can deliver safely, please ensure the access route is firm and clear of overhead obstructions.

We recommend using timber laths to mark out the exact area where the sub-base will be laid. This helps our drivers tip the material exactly where your plant operators need it, saving you time on double-handling the material across the site.

Shingles (10mm/20mm)

Should I choose 10mm or 20mm shingle?

It depends on the application:

10mm Shingle: Best for pipe bedding, fine drainage, and small garden borders.

20mm Shingle: Ideal for driveways, larger drainage blankets, soakaways, and areas with higher foot traffic.

Is shingle suitable for driveways?

Yes, 20mm shingle is a very popular choice for driveways across Essex, London & Kent.

It provides a permeable surface that helps with SUDS (Sustainable Urban Drainage Systems) compliance, reducing the risk of surface flooding. For a professional finish, ensure you have a solid sub-base of MOT Type 1 and use timber laths or high-quality edging to keep the shingle contained.

How much shingle do I need?

For a standard decorative layer or driveway, we recommend a depth of roughly 50mm. At this depth, one tonne of shingle will cover approximately 12 to 14 square metres.

If you are using it for drainage or pipe bedding, the tonnage will be higher depending on the width and depth of your trenches. Our team can provide a precise estimate based on your site measurements in London.

How is the shingle delivered?

We deliver in bulk via our 8-wheel tippers, which can carry up to 20 tonnes per trip.

Our drivers are experienced in navigating tight residential streets and busy construction sites throughout Essex, London & Kent. To make the process seamless, please ensure there is adequate space for the vehicle to tip safely and use timber laths to signal the exact drop-off point.

Does the color of the shingle vary?

As shingle is a natural quarried product, there can be slight variations in color depending on the source.

Most of our supply features a blend of browns, greys, and buffs that complement both modern and traditional builds. If you are matching existing stone on a London site, let us know, and we will do our best to provide a consistent match.

MOT Type 1

What exactly is MOT Type 1?

MOT Type 1 is a high-quality granular sub-base material. The name comes from the Ministry of Transport (MOT) specifications. It is usually made from crushed concrete, limestone, or granite.

The material is graded from 40mm down to dust. This specific mix ensures that when it is compacted, the smaller particles fill the gaps between the larger stones, creating a solid, load-bearing surface that won’t shift under pressure.

How much MOT Type 1 do I need for my project?

As a general rule of thumb, one tonne of MOT Type 1 covers approximately 4.5 to 5 square metres at a compacted depth of 100mm.

However, this can vary based on the specific density of the stone and how heavily it is compacted. If you are unsure, our team can help you calculate the exact tonnage required for your site in London to ensure you don’t over-order or run short.

How is the material delivered to site?

We deliver our aggregates using our modern fleet of 8-wheel tippers. These vehicles are ideal for bulk deliveries across Essex, London & Kent, capable of carrying up to 20 tonnes per load.

Our drivers are highly experienced in navigating tight London sites. To help our drivers, it is always useful if you use timber laths to clearly mark out the tipping area and ensure the access route is clear of obstructions before we arrive.

Is your MOT Type 1 compliant with London regulations?

Yes. All our aggregates are sourced from reputable quarries and meet the current Department of Transport specifications.

Furthermore, because we operate within London, our entire delivery fleet is fully ULEZ compliant and FORS Silver accredited. This ensures that your site stays compliant with environmental and safety standards from the moment the material is delivered.
