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.
At Mayo Stone Supplies Ltd, we supply our Type 1 aggregate across Manchester and nationwide from a network of quarries. Combined with a comprehensive transportation network, this enables us to provide flexible and rapid delivery across the UK, not just here in Manchester.
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 supply it using gritstone, limestone and granite. 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.
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.
