The heavy single-size, 20mm screenings for structural concrete, soak wells and drainage that moves serious water.
20mm is the big single-size: the standard coarse aggregate for structural concrete and the material of choice where drainage needs maximum void space, soak wells, infiltration trenches, gabion fill and heavy subsoil drains.
Clean, washed and consistently cubic from quality basalt sources, it locks together well enough to place and stays open enough to drain for decades. By the tonne, the truck or the bulka bag.
