They are a highly versatile, yet reasonably priced. Paving slabs are made from a high strength concrete in varying sizes and colour. Whilst grey is typically the cheapest, they come in a range of alternative colours, finishes and textures; from flat grey to multi-coloured replica stone, even slabs that look like wood and logs. The range is endless so they are ideal for any property and for any budget.
Excavate the area to be slabbed. You will need a clearance of 240mm. Once the ground is clear you can lay your sub-base at 150mm, which should be well compacted. There are two ways of laying slabs. One is to put five or six small piles or mortar on to the hardcore then put your slab in place and tap it down until its level. Then, repeat this with your next slab using a level making sure that they are level. The second way is to compact about 40mm of sharp sand and then screed this off level and lay your slabs straight on to this. After all your slabs are laid you can fill any joints with a joint stabiliser.
