Slab paving is a great material to use to create a sturdy shed base.
Start by measuring out the area where your shed is going to be. This needs to be the size of your shed, plus about 10-20cm extra each way. Mark it out with string and pegs, make sure it’s square, and dig it down to about 6cm deep.
Then create a sand and cement mixture and put a layer down, followed by your paving slabs. Make sure you start in one corner and use a rubber mallet and spirit level to make sure they’re as level as possible. Leave this to set and you’re ready to use your shed base.
