지하실 바닥 콘크리트 가이드

Basement floors are typically 4 inches thick using 3,000–3,500 PSI concrete over a 4-inch compacted gravel base and 6-mil poly vapor barrier. Slope toward floor drain. Add control joints every 10–15 feet in both directions. A 1,000 sq ft basement at 4 inches needs about 12.5 cubic yards.
