Is the original slab worth building on?
The concrete patio behind a Deer Park house from the 1970s was usually poured thin, without steel, and without any expectation of carrying a roof structure or a masonry kitchen. Sometimes it has held up fine and only needs cleaning or an overlay. Often it has cracked and settled toward the house, which sends rain against the foundation instead of away from it. We evaluate the slab first because everything else in the plan either sits on it or replaces it, and the answer changes the whole budget. A cracked slab is a decision, not a detail.
If the slab is sound but too small, we extend it with new footings for the cover columns and a thickened section under the kitchen. If it is failing, removing it and pouring a new slab with proper slope, steel, and drainage under the whole outdoor room costs less than working around it. Where a pool already exists, the new hardscape has to meet the pool deck at a clean joint with drainage between them, so the pool's elevations and equipment locations are part of our layout from the start.
