I curently have a concrete slab patio 3m x 4m that i want to re do with nicer slabs. The current slabs are bedded down in 3 foot of concrete and so pulling them up is out of the question.
Can i overlay and whta preparation would i need to do first, can i just put a layer of sand over the top and lay them over?
I have checked the height tollerance and this is fine.
