Pouring a new basement floor for an addition, finished basement, or replacing a failed slab starts with proper subgrade prep, a vapor barrier, and reinforcement. Cousins Concrete Services Inc handles it start to finish for homes across Cook, Lake, Porter, and La Porte Counties.
Typical basement slabs are poured 4 inches thick over a compacted gravel base and a 6-mil poly vapor barrier, which keeps moisture from wicking up through the concrete.
