Tip: An additional border of approximately 6″ (150mm) around the edge of the base will allow you to fill with pea shingle or a decorative stone preventing the possibility of ‘splash-back’ as rain drips to floor. This can be prepared before of after the base has been laid.
Lay a bed of sharp sand over the entire base area compact and level. Tip: It is advisable to place a polythene membrane down prior to the top layer of sand being laid this will stop any damp rising through the slabs to the building.
Starting in one corner lay the first slab into its position, carefully levelling in all directions using a spirit level. Continue along one complete side and edge creating a right angle. These first slabs are the important ones as these will determine the overall level of the base, then you can start to fill in the remainder of the slabs keep levelling and checking. Tip: Have a bucket of the dry mix next to you, you can then add or remove material to keep each slab level.
If you need to cut any slabs, measure and mark the slab, then using the bolster and hammer score the slab along its length and edges, one heavier blow towards the centre of the score line should break the slab (some slabs are more brittle than others and this may not always work) have the side that has been cut facing into the area, this will leave the good edge showing.
