What drives slab cost
Slab pricing depends on:
- Square footage and slab thickness
- Site prep, grading, and gravel base
- Rebar or wire mesh reinforcement
- Finish (broom, smooth, or stamped)
Thickness matters
A standard 4-inch slab works for patios and sheds. Garages, driveways, and heavy loads need 5 to 6 inches and reinforcement, which adds material and cost but prevents cracking.
