MOT Type 1 Sub Base – High-Quality, Durable Ground Preparation

Our MOT Type 1 is a premium sub base material made from finely crushed limestone (or granite in modern variations), certified to meet the Department of Transport's Specification for Highway Works, Clause 803.

With particle sizes ranging from 40mm down to dust, this material compacts tightly to form a strong, stable foundation—ideal for driveways, patios, paths, and other landscaping projects.

Recognised for its excellent load-bearing properties, MOT Type 1 has been a trusted choice for professional groundworks for decades. Whether you're tackling a small garden path or a large-scale construction job, it delivers long-lasting durability and reliability.
