MOT Type 1 Sub Base Delivered Loose

MOT Type 1 Sub Base Clause 803 — also widely known as MOT Type 1 (MOT standing for Ministry of Transport) — is a crushed limestone sub base material graded to meet the strict requirements of Clause 803 of the Specification for Highway Works. It is the go to material for road construction, highway projects, and any application where a certified, specification compliant sub base is required.

If your project doesn't require compliance with Clause 803 — for example, if you're a builder, landscaper, or carrying out general groundworks — our standard Type 1 sub base may be a more cost effective option. Click here to view our standard Type 1 (DOT Type 1)
