MOT Type 1 Sub Base

When it comes to construction and landscaping, the strength of your finished project is only as good as the foundation beneath it. Our MOT Type 1 Sub-Base Aggregate is the industry-standard choice for creating a stable, high-load-bearing surface that stands the test of time. Whether you are laying a new driveway, a garden path, or a heavy-duty patio, this aggregate provides the structural integrity required to prevent sinking, shifting, and cracking. What is MOT Type 1? MOT Type 1 (named after the Ministry of Transport specifications) is a high-quality crushed aggregate ranging in size from 40mm down to fine dust. This specific grading is what makes it so effective; the various particle sizes allow the material to interlock perfectly when compacted, creating a solid, level, and incredibly dense “sub-base” layer.
