MOT Type 3 is a high-quality sub-base aggregate with reduced fines, designed to promote free drainage while maintaining strength and stability. It is commonly used in the construction of permeable surfaces where Sustainable Drainage Systems (SuDS) compliance is required.
0–40mm screened limestone for optimal load-bearing and drainage
Reduced fines content (not zero fines) for improved water flow
Ideal for driveways, footpaths, and other permeable surface applications
SuDS-compliant and widely approved for environmentally responsible groundwork
