Slabs & Foundations in Kennewick, WA & the Tri-Cities

Standard residential garage slabs are 4 inches thick. Shop and workshop slabs that hold lifts, presses, or heavy vehicles step up to 5–6 inches with rebar on 18-inch centers. We pour to engineered drawings when required and to industry best practice when not.

Yes. We pour footings, stem walls, and slab-on-grade foundations for accessory dwelling units, garages, additions, and shops across the Tri-Cities. We coordinate with your inspector and structural engineer and stage pours so framing can start on schedule.

A properly built slab starts with compacted subgrade, then a layer of crushed base rock, then a vapor barrier in conditioned spaces, then the concrete with rebar or fiber reinforcement. Skipping any of these layers is how slabs settle, crack, and fail early.

Framing typically starts 5–7 days after a foundation pour, once the concrete has reached enough strength to handle bottom-plate loads. Full design strength is 28 days. We coordinate with your framer so timing lines up and the project keeps moving.

Yes. We pour through Tri-Cities winters using hot water in the mix, accelerators, and insulated blankets to protect green concrete from freezing. Some sub-freezing days are skipped, but most of the winter calendar is pourable with the right setup.
