How to lay a paving slab base…

Excavate a 15-18cm deep hole accordingly to your foundation plan and you may leave 10-15 cm extra beyond the boundaries of the cabin to allow for an extra area of dry ground around the building. Cover the surface with a damp proof membrane or similar.

Lay down the subbase of 15cm of gravel or MOT 1 granules. Even and level the subbase by using a garden rake and compact it by using a roller or tamper.

Now lay down 3cm of sand, even with shovel and rake but don’t compact.

Start placing down paving slabs. Leave 3mm distance between the slabs, push and tap them to place and level.

Finally infill the gaps between the slabs with sand. Sand in the gaps must be well compacted, therefore push the sand tightly into the gaps.
