STEP 1: Preparation
Mark out the area of the driveway or patio with spray paint or string.
Locate any gas pipes, electricity cables or broadband cables etc. using a CAT and Genny scanner. Avoid these areas when excavating!
STEP 2: Lower Geo-Membrane
A permeable geo-membrane is laid over the sub-grade to prevent the sub-base sinking into the sub-grade. A geo-grid is laid on top of the geo-membrane which will hold the sub-base in place. The geo-membrane should come up to the point of the edgings or kerbs.
STEP 3: Sub-Base
The sub-base for permeable driveways is a very specific material. The sub-base must be fine-free. This allows the stone to absorb water better. The sub-base is made up of two layers on a permeable block driveway, separated by a Geo-Membrane.
The lower layer is 250mm deep and made up of material where the individual stones are 10-63mm depending on the job.
Lay a second Geo-Membrane between the Lower Sub-Base and the Upper Sub-Base to prevent the smaller stones of the upper base sinking down. The upper layer (100mm) consists of stones with individual dimensions of 5-20mm depending on the job.
STEP 4: Bedding
The bedding is spread and screeded. The screeding process can be trickier due to the coarse nature of the bedding so a screeding tool is recommended.
Do not allow any debris such as leaves to get on top of the bedding before the blocks are laid.

STEP 5: Laying of Permeable Blocks
Lay the blocks by hand in the same way as a conventional block driveway.
Blocks can be 60mm or 80mm thick.
The way the permeable blocks are constructed allows water to run between the blocks into the bedding and sub-base beneath.
STEP 6: Cutting In
Blocks are cut in the same way as a conventional block driveway.
Step 5: Laying permeable blocks
STEP 7: Jointing
Jointing grit is used in place of sharp sand on a permeable block driveway. Sharp sand must never be used, as any fine materials will make it harder for the driveway to absorb water. Brush the grit in. There should be enough jointing grit over the whole drive so that it comes up to the level of the blocks.
STEP 8: Compaction
Use a wacker plate to compress the blocks and jointing together.
