Buying Crushed Concrete For Driveways Patios

Buying concrete in dry, premixed bags makes sense for relatively small patio slabs.To get an idea of how many bags you would need, a 50-square-foot slab at 4 inches thick needs about 28 80-pound bags or 38 60-pound bags.You can buy bagged concrete a local home center or lumberyard, and you can rent a concrete mixer at any large rental outlet.
