MOT Type 3 Aggregates

MOT Type 3 is a coarse, well graded aggregate material. due to its drainage ability, it is suitable for a wide range of applications from sports pitches to paving and pathways.

Our Type 3 aggregate, often referred to as MOT Type 3 sub-base, is a coarse well graded granular material typically used in road construction and as a base layer for other construction materials.

Produced from crushed rock which is screened and graded, giving a blended material with particles that range in size from 0mm to 40mm.  Type 3 is an open graded material, and has fewer fines compared to other sub-base solutions like MOT Type 1. This designed characteristic allows water to drain freely, making it an excellent choice for projects where efficient drainage is a priority.

Type 3 can be easily compacted, ensuring that while water permeates at a high rate, the aggregate retains its strong load-bearing qualities.

The versatility of our Type 3 aggregate is evident in its wide range of applications.  It's commonly used as a sub-base material for sports pitches, ensuring that the ground remains stable and water drains away efficiently.  It's also perfect for permeable paving and Sustainable Drainage Systems (SuDS). Other typical uses include equestrian arenas, driveways, paths, patios and tennis courts.

Our Type 3 aggregate complies fully with Specification for Highway Works Clause 805 (SHW 805), so you can be confident when you're using our Type 3 aggregate, you are selecting a product that meets rigorous industry standards.

Sourced from across our network of quarries nationwide, our Type 3 aggregate is a reliable choice for projects that require a strong yet permeable sub-base.
