Most driveway problems, such as sinking, rutting and weeds, start with a thin base. We dig out to the right depth and build the base up in compacted layers before a single block goes down.

For a car driveway we excavate to around 250 mm, lay a geotextile membrane, and build up 150 mm of Type 1 sub-base compacted in layers with a plate compactor. The blocks are laid on a sharp sand bed, cut cleanly at the edges and locked in with kiln-dried sand.
We lay Marshalls and Brett blocks in the main ranges, and we set every edge with a concreted kerb or edging course so the blocks cannot spread. We also check where the surface water will go before we quote, because a front driveway must drain onto your own land or into a soakaway.
Around 250 mm for cars, deeper on soft or clay ground.
Type 1 sub-base laid and compacted in stages, not in one go.
Kerbs and edging set in concrete so the blocks stay put.
Falls, channel drains and soakaways checked before we quote.
Old surface and soil taken away and recycled.
On the sub-base and laying, written into your contract.

A cracked concrete drive was dug out and replaced with 62 m² of charcoal and grey blocks in a curved layout, with a channel drain across the garage entrance. Finished in seven working days.

Not if the surface is permeable or the water drains onto your own garden or a soakaway. A non-permeable surface over 5 m² draining onto the road needs planning permission, so we design every front driveway to drain on your land.
Very few, if the joints are kept full of kiln-dried sand. We fill them on the day we finish and top them up at our six-month visit.
