Permeable block paving is an alternative to loose gravel or permeable tarmac. The base preparation is different for this type of paving as it has to be fully permeable. MOT type3 hardcore is laid to a depth of 6-12”, with a 2” layer of 10mm grit screeded over surface. Blocks are then laid on this surface with further 10mm grit brushed into the extra wide joints of the blocks to enable water to soak away freely. This is a fully permeable driveway.
