Hi there,
I am planning to lay a patio over an area of 60 square meters but some of that area has previously been concreted at a height of 12cm above the ground level and the rest is turf. I was wondering what would be the best option for laying an even patio over it all; would it be to put down concrete over the turfed areas and then lay the slabs? or would it be feasible to only put down hardcore and a thinner layer of concrete on the turf?
Any advice would be geatly appreciated!
