Permeable paving is designed to help with the requirements of Sustainable Urban Drainage Schemes (SUDS). We now offer a bevelled edge 400mm x 400mm hydraulically pressed slab that is designed to allow water to flow between the specially designed gaps.
The gaps between the slabs should be filled with 2/6.3mm material (to BS EN 12620) to allow water to permeate into a 50mm layer of the same material. Below this layer there should be a layer of 4/20mm of open-graded granular sub-base type 4/20 (to BS EN 13242).
The resultant 8mm wide gaps create 2% of the surface area as voids.
Permeable slabs are available in 50 and 65mm thicknesses and in both grey and buff colours.
