Product Details

10/20mm Cleanstone is a clean, angular aggregate graded from 10/20m and supplied free from fines, offering high permeability and strong load‑bearing characteristics. Its open grading supports efficient water movement, making it suitable for drainage layers and structural applications where fines‑free performance is essential.

This aggregate is widely used in drainage systems, surface dressing, and as a component in concrete mixes where water management and strength are both required. The larger angular particles provide enhanced stability while preserving voids for drainage, helping to maintain long‑term performance.

Produced in accordance with SHW Series 500, BS EN 12620, BS EN 13043, and BS EN 13242, 10/20mm Cleanstone is a compliant and dependable solution for drainage and structural construction works.
