Product Details

10/63 mm Cleanstone is a large, clean aggregate graded from 10/63  mm and supplied free from fines, designed for heavy‑duty drainage and groundwork applications. The wide grading range provides strong load distribution while maintaining substantial void space for rapid water movement.

It is commonly specified for permeable paving bases, drainage layers, sub‑bases, and temporary access roads, particularly where strength and permeability must be achieved simultaneously. The angular nature of the aggregate supports stability under load without compromising drainage performance.

Produced in accordance with SHW Series 500, BS EN 12620, BS EN 13043, and BS EN 13242, 10/63 mm Cleanstone is a compliant and reliable solution for demanding drainage and infrastructure projects.

Product supply may be subject to geographic availability.
