We prep and pour Concrete Slabs

All concrete is subject to cracking over time. The most crucial part of keeping cracks under control and to a minimum is subgrade prep. Many fly by night concrete slab contractors will pour the concrete over an inch or two of loose gravel, or perhaps none at all. We excavate down 6-8" and overcut the slab by 8-12" all around and install a solid compacted gravel base. An "overcut" means we excavate beyond the slab size itself giving it a much more solid base. If the slab is 10x14', we will excavate 12x16' to a depth of 12-15", install 6-8" of compacted gravel, then 6" of fiber reinforced 4000+ psi concrete. 

Typically on non-heated, outdoor slabs for sheds and such vapor barriers are not needed nor recommended. If you intend to heat the structure, we can gladly install a vapor barrier.
