Slab foundation building in Sherwood OR - a floor that starts on solid ground
Planning a new home, addition or shop on a slab? We dig out and pack the ground first so your floor has something solid under it.
What does building a slab foundation in Sherwood involve?
Slab foundation building in Sherwood, OR means pouring a concrete floor straight onto prepared ground, called a slab-on-grade, which later carries your home's carpet, tile or wood flooring. Most of the job happens before the concrete truck shows up, in the digging, packing and layers that go under it.
Most folks call us when they're planning a new home, an addition or a shop, and the price mostly turns on the slab's size, how much soft ground has to come out, and what goes under the concrete for the flooring you have in mind. The schedule turns on the permit, so we settle at the estimate who applies for it and help with the paperwork when your project needs it. The estimate comes with a written scope that lists each step, so you can see what you're paying for. If your plans call for walls and footings instead of a slab, that's our foundation installation work.

Why folks trust Sherwood Concrete with slab foundations
When I was hauling forms as a helper, the slabs that failed usually had a ground problem, not a steel problem. A slab on poor ground is far more likely to fail whatever's inside it, so we dig out and pack the base first. If the budget's tight, I'd rather trim the finish than the base.
Before we pour, we lay the moisture barrier your flooring calls for and set insulation around the slab's edge, which Oregon's Building Codes Division requires on slab-on-grade floors. Then we place the concrete, cut control joints so cracks follow a line we chose, and give it time to cure and harden before anything gets built on it.
Slab foundation questions we hear
How much does a slab foundation cost in Sherwood, OR?
Installed slab foundation work around Portland usually runs about $8 to $22 per square foot, counting materials, labor and site prep, and that's the going rate in the area, not our price. Where your slab lands depends on how much ground has to come out and be packed, the reinforcement, and the barriers and insulation under it. The estimate's written scope shows what's in yours.
Do I need a permit to build a slab foundation in Sherwood?
Yes, because the state's permit rules require one for all new construction, and the person doing the work, you or your contractor, gets it. Work can begin once the permit is issued, so build that time into your plans. We agree at the estimate who applies and help with the paperwork when your project needs it.
Does a concrete contractor need a license in Oregon to build a slab?
Yes, Oregon law generally requires anyone paid for construction work that improves your property to be licensed through the state's Construction Contractors Board. Ask any contractor you're considering for their license before you hire them.
Do tile or wood floors over a concrete slab need moisture protection?
Yes, national industry guidance says a slab needs moisture protection when carpet, tile, wood or resilient flooring like vinyl will cover it. Water vapor coming up through the concrete can loosen flooring glue and lead to damage, trip hazards and possibly mold. The same guidance says the slab should cure, dry out and be tested for moisture before flooring goes in.
How do I check my Sherwood lot for soft soil or flood risk before building?
Type your address into Oregon's HazVu hazard viewer to see mapped hazards like Cascadia earthquake shaking, earthquake soft soil, landslide and 100-year flooding. For a new home, the state's Design Criteria Hub also shows site values such as frost line depth, seismic design category and radon mitigation. Bring what you find to the estimate and we'll talk through what it means for the ground work.
What causes cracks in a new concrete slab?
Most cracks come from concrete shrinking as it dries, temperature swings, heavy loads, or a base that was raked level instead of dug out and packed. The reinforcement covered above limits how wide they open, and the control joints we cut give them a straight line to follow. A packed base is what keeps the slab from sinking along with the dirt.
