MOT Type 3 Aggregate

Overview

Groundworx Grabhire Ltd. supplies MOT Type 3 Aggregate, a highly permeable sub-base material specifically designed for Sustainable Urban Drainage Systems (SuDS) and other drainage-focused projects. Also referred to as Type 3 Sub Base, this aggregate provides stability while allowing water to drain freely, making it ideal for projects requiring efficient water management.

MOT Type 3 Aggregate consists of crushed stone graded to a size range of 0-63mm, with fewer fines than MOT Type 1 or Type 2. Its excellent drainage capabilities make it an essential component for environmentally conscious construction and landscaping projects.

What is MOT Type 3 Aggregate?

MOT Type 3 Aggregate is a free-draining sub-base material designed to meet SuDS guidelines. By reducing surface water runoff, it supports sustainable construction practices. This aggregate features larger stones and minimal fines, ensuring void spaces that allow water to pass through effectively.

MOT Type 3 Aggregate is perfect for applications requiring a stable, durable, and permeable foundation, such as driveways, car parks, and pathways in drainage-sensitive areas. MOT Type 3 must comply with Department of Transport Specification for Highway Works, clause 805 (SHW 805).
