Hello
I need some guidance: I'm about to embark on a project to replace the concrete slabs on the footpath which looks dated with slate slabs. I started to remove 2 of 63 concrete paving stones which are cemented to a concrete base. The 2 Concrete paving stones removed so far, require significant amounts of brute force to separate from the base (I'm a strong 6'4" guy!) even breaking them with a sledge hammer requires significant effort. I'm now considering removing all the loose material like grout, pressure washing the area down and installing the new slate paving on top of the existing concrete paving, is this a good or a bad idea?
