High-Quality MOT Type 1 Aggregates Essex, London, and Kent
When it comes to building a stable sub-base, there is no substitute for quality materials. We supply and deliver MOT Type 1 London, the industry-standard aggregate for creating a load-bearing surface for roads, car parks, and building foundations.
Our material is sourced from reputable quarries to ensure it meets the strict Department of Transport (DoT) specifications. Whether you are working on a major highway project or a residential driveway in Essex, London, or Kent, our Type 1 sub-base provides the durability required for a long-lasting finish.
Superior Strength and Interlocking Grading
The strength of MOT Type 1 lies in its specific grading. It consists of a mix of larger stones (up to 40mm) down to fine dust, which allows the material to interlock perfectly when compacted.
This creates a solid, non-porous layer that prevents shifting and provides excellent drainage—a vital factor for any groundworks project. When you order from us, you can be certain the material meets the crushing and abrasion resistance standards necessary for heavy-traffic applications.

Frequently Asked Questions
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.
