How Much Does It Cost to Pour a Concrete Slab?

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.
