hello.im going to lay a small patio in my garden but its part concrete and turf at the moment. so whats best method for laying please? over concrete i cant see a problem but i dont want any sinking in the soil. so how deep do i need to dig out and would gravel compacted with sand cement mix over that do the trick?? thanks
Dig out about 6" to allow room for the hardcore, mortar and paving slabs. Now barrow in a 3" layer of hardcore. Use a rake to distribute it, and even out any bumps. The rubble will form a good solid base for the patio. Use a whacker plate to compact and level the hardcore. Lay the slabs on a 6:1 mortar mix onto the hardcore.
