Permeable Block Paving Layer

This 6mm grey carboniferous limestone is the ideal product to use for the top layer of a permeable sub-base when laying block paving, slabs or grid systems.

Installed as part of a SUDs compliant installation the combination of aggregates allows infiltration of the water slowing the run off into the ground and not into already overworked drains and water courses, helping to prevent flash flooding.

Size – 6mm
Rock Type – Carboniferous Limestone
