How would I go about laying a concrete slab base for a garage floor. The garage is attached to the house. Do I :-
1.Dig out and lay the foundations and build the 3 sides up to ground level.
2.As the ground has already been prepared with compacted hardcore, can I just dig down the 150mm then lay the DPM (1200 visqueen).
3. Pour the concrete in up to ground level.
