Pouring a concrete slab costs $6 to $12 per square foot, depending on the thickness, size, and purpose. Concrete patios are typically 4 inches thick and range from a basic broom-swept finish to complex colors, stamping, and designs.
Concrete slab garage floors, driveways, and foundations are typically 6 inches thick and require wire mesh or rebar reinforcement to make sure it's durable enough to withstand the weight of heavy vehicles or a house.
