Monolithic slab foundations

One pour, footing and floor together

A monolithic slab has thickened edges that act as the footing, poured at the same time as the floor. One pour means fewer steps, fewer joints and a faster path from bare ground to a building. It is a common choice for shops, detached garages and outbuildings on reasonably flat sites.

We work from your building plans or kit specs, set the forms and reinforcement, place anchor bolts where the walls will go, and pour. If the building needs a permit, the county usually inspects the forms and steel before the pour, and we schedule around that.

Local know-how

Shops and outbuildings on rural lots

Shops, pole barns and garages are a big part of life on acreage in Mason and Grays Harbor counties. Access matters on these jobs: how a concrete truck gets to the pad, and whether the ground stays firm in the wet months. We look at that at the quote so pour day goes smoothly.

Questions

Monolithic Slabs FAQ

Have a question that isn't here? Call 360-463-1098.

What is the difference between a monolithic slab and a stem wall foundation?

A monolithic slab pours the footing and floor together and suits flat sites. A stem wall foundation builds the footing and short walls first, then the floor, and handles sloped sites better. We will tell you which fits your lot.

Do I need a permit for a shop slab?

If the building itself needs a permit, the foundation is part of it, and an inspection is usually required before the pour. Your building permit will say. We work with the inspection schedule.

Can you prep the site too?

Yes. Clearing, grading and base work are done in-house with our small tractor, so there is one crew from dirt to slab.
