Concrete Slabs & Shop Floors
Concrete Slabs & Shop Floors built by Greg
A shop or barn floor has to take a lot: a parked truck, a tractor, a car lift, horses, a workbench that never moves. It also has to stay dry, because a slab that wicks ground moisture leaves tools rusting and stored gear smelling of mildew. If you're putting up a new pole building, garage or barndominium, or you need a pad for an RV, a shed or equipment, the slab is the one part you can't redo later without tearing everything out. It pays to have it laid out and poured by someone who builds on slabs for a living.
Slab work is what Greg Myers Construction is known for. The company's Google profile lists it as Concrete Slab Foundation Specialists, and Greg pours the slab floors under the barn homes, pole barns, shops and garages he builds. His photos include a big open barn interior with exposed trusses set on a concrete slab floor. For owners from Rainier and Yelm to Roy and Tenino, each slab starts with excavation to firm ground and a compacted base, then a vapor barrier, steel, thickened edges where walls or posts bear, and a finish suited to how you'll use the floor.

Questions
Concrete Slabs & Shop Floors FAQs
Why does my garage or shop floor stay damp?
Usually because ground moisture is moving up through a slab with no vapor barrier, or warm, wet air is condensing on cold concrete. With high water tables and long wet winters in this area, Greg puts a vapor barrier under every interior slab and builds the base so water drains away from the building. Good ventilation in the building handles the rest.
How is a concrete slab priced?
By the size and thickness of the slab, the excavation and base rock the site needs, steel, insulation if the space will be heated, the finish, and how easily a truck or pump can reach the spot. Greg's small company overhead and big company buying power help keep that number fair. A free on-site estimate prices your exact building.
Can you pour a slab inside an existing pole barn?
Yes. Pouring inside a standing building takes more planning for truck or pump access and working around the posts, but it's very doable. Greg grades and compacts the dirt floor, lays the barrier and steel, and pours in sections if the layout calls for it.
How thick should my shop slab be?
It depends on what will sit on it. A floor for cars and storage needs less than one carrying a loaded truck, a tractor or a car lift, which may call for thicker sections or footings under the lift posts. Greg sizes the slab to your use and to the plans the county approves.
Can you build the shop too, not just the slab?
Yes. Greg builds pole barns, garages, shops and barndominiums, so the slab, the framing and the roof can all be one contract with one person to call.
