Frequently Asked Questions
How thick should a concrete slab be?
Standard residential slabs are typically 4 inches thick, while driveways or slabs supporting heavy loads may need 5-6 inches or more.
Why include a waste buffer?
Uneven subgrade, spillage, and form imperfections typically mean you'll need 5-10% more concrete than the exact calculated volume.
Does this include excavation and forms?
No, this estimates concrete material and finishing labor only. Excavation, gravel base, rebar/mesh, and forming are typically additional costs.
