I kind of done my own block paved drive way with a labourer using my own electric compactor. The existing ground was dug up and laid with crushed concrete with a man and his mechanical digger with a sub base of approx. 100 to 150mm.
The drive is slight sloping away from the house. If insufficient sharp sand is laid as we get closer to the house (we need to butt against an existing tiled floor), what can happen to the block paving? I think we have laid maybe 30 or 40mm in some areas, but not level all round.
Also is silver sand some special sort of sand that goes hard after it is brushed into the voids of the block paving? Does it also help to stabilise the paving to stop it move around in small amounts?
Thanks.
