MOT Type 3 is a high-performance, permeable base aggregate designed for use in sustainable urban drainage systems (SuDS) and other construction projects requiring effective water management.
Comprising a mix of crushed stone and finer particles, this aggregate is slightly larger and more open-graded than MOT Type 1, typically ranging from 40mm down to 4mm.
The larger particle size and reduced fines allow for excellent drainage properties, making MOT Type 3 ideal for use in permeable pavements, sub-bases for sports pitches, and other applications where water runoff needs to be controlled. Its robust and stable nature provides a solid foundation for paths, roads, and driveways, while ensuring compliance with SuDS regulations.
