MOT Type 1 Aggregates

MOT Type 1 is a crushed aggregate that is ideal as a sub-base for driveways and paths when compacted, with excellent load bearing properties.

Whether a sub-base for a domestic project or a large-scale construction scheme, a solid foundation is fundamentally important. And one of the most popular materials for any properly constructed foundation is Type 1, also widely known as MOT Type 1 sub-base aggregate.

We supply our Type 1 aggregate across our network of quarries nationwide. Combined with a comprehensive transportation network, this enables us to provide flexible and rapid delivery across the UK.  

Type 1 is a granular sub-base material, consisting of aggregate that is crushed and screened to provide a blend of aggregate size from 40mm down to fine dust. This range of particle sizes ensures the material is easy to compact to create a solid foundation, with excellent load bearing capacity.

Our Type 1 complies to all standards outlined in SHW Clause 803, making this an approved sub-base in the construction sector, ideal for use in the construction of roads, highways, and pathways.

The composition of our Type 1 depends on the geology of the supplying quarry, and we can produce it using gritstone, limestone, granite, or basalt.  We also produce Type 1 containing recycled materials, making this a more sustainable option, supporting a circular economy.

Type 1 guarantees a solid and enduring base, making it an ideal choice for a multitude of applications.

High Load-Bearing Capacity

MOT Type 1 is renowned for its excellent load-bearing properties. Once compacted, it provides a strong and stable foundation that can support heavy loads such as vehicles, construction equipment, and structures. This makes it ideal for roads, driveways, and car parks, where significant weight is applied over time.

Excellent Compaction

MOT Type 1 consists of a well-graded mixture of crushed stone and fine materials, which allows it to compact tightly and create a solid, stable sub-base layer. Its ability to form a dense, interlocking structure ensures minimal movement or settlement, providing long-term stability to any surface built on top of it.

Frost Resistance

MOT Type 1 offers good frost resistance, as its fine materials and compaction reduce water penetration into the sub-base. By limiting water retention, it minimizes the risk of frost heave and cracking in colder climates, which is critical for maintaining structural integrity during freeze-thaw cycles.

Why MOT Type 1?

MOT Type 1 is one of the most widely used aggregates for sub-base construction, known for its high quality and versatility. It provides a stable and durable foundation for roads, driveways, footpaths, and other surfaces that require a load-bearing sub-base. 

Due to its strength and compactability, MOT Type 1 is highly durable, making it suitable for long-lasting projects. It resists wear and tear from traffic, environmental factors, and weather conditions, helping to extend the lifespan of the surface above it.

Thanks to its high compaction and interlocking particles, MOT Type 1 creates a solid base that prevents uneven settlement or movement in the surface above. This is particularly important for preventing cracks or shifting in paved surfaces like driveways, roads, and paths.
