Paving and Driveway Aggregates

Permeable Pavement Materials

Driveways handle surface water by being permeable. Free draining permeable pavements incorporate a sub-base of a specified material such as 10/63mm, 4/20mm and 2/6mm clean stone.

EcoSand

BS 7533-3:2005. Day Group's inert EcoSand, produced from recycled glass, is a sustainable alternative to sharp washed sand on which to lay block paviors and slabs. Due to its angular shape, free draining nature and low bulk density, it gives a greater coverage per tonne, coupled with excellent technical performance.
