Product Details
20/40 mm Cleanstone is a coarse, angular aggregate graded from 20/40 mm and supplied free from fines, offering excellent drainage capacity and long‑term durability. The large particle size creates significant voids, allowing water to move quickly through the layer and reducing the risk of waterlogging.
This aggregate is widely used in drainage systems, soakaways, French drains, sports construction, and equestrian surfaces, as well as civil engineering applications where rapid drainage and resilience are critical. Its angular structure provides stability while maintaining consistent permeability.
Produced in accordance with SHW Series 500, BS EN 12620, BS EN 13043, and BS EN 13242, 20/40 mm Cleanstone is a compliant and dependable solution for heavy‑duty drainage and specialist construction needs.
Product supply may be subject to geographic availability.
