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.
