MOT Type 3 Sub Base

MOT Type 3 Sub Base, also known as DOT Type 3, is a certified aggregate made from limestone, granite or basalt and graded to SHW Clause 805. Unlike Type 1, it contains fewer fines, giving it an open structure that is free-draining and ideal for Sustainable Urban Drainage Systems (SuDS). Its angular, coarse particles interlock to provide stability while allowing water to filter through, making it suitable for driveways, permeable paving, sports fields, equestrian arenas and construction bases.
