Product Details

4/20mm Cleanstone is a clean, angular aggregate graded from 4/20mm and supplied free from fines, providing excellent permeability alongside reliable structural support. Its open grading allows water to pass freely through the material, making it well suited to use as a base or intermediate layer within permeable paving systems (SuDS), where effective drainage and load distribution are essential.

This aggregate is also commonly specified as infill for ground reinforcement and grid systems used in parking areas and tree root protection, as well as a bedding layer beneath permeable paving. The angular particle shape contributes to stability while maintaining open voids for water infiltration, helping to manage surface water without compromising strength.

Produced in accordance with SHW Series 500, BS EN 12620, BS EN 13043, and BS EN 13242, 4/20mm Cleanstone is a compliant and dependable solution for permeable construction, drainage, and ground stabilisation applications.
