Concrete Slabs for Garages and Sheds
A garage or shed is only as good as the slab under it. We prepare the base, set the forms and steel and place a slab with the right thickness and edge for the building and the loads, with a smooth, flat surface and a slight pitch for drainage where it is needed.

- SteelMesh or bars as required

Common questions
How thick should a garage slab be?
Many garage slabs are about four inches thick, with thicker edges where walls bear. Heavy equipment may call for more. We size it to your use.
Can a garage slab be sealed or coated?
Yes. A sealer or a coating protects the surface. See our garage floor coatings.
