Concrete Foundations in Delaware

A foundation is not just what the structure sits on. It is the part that keeps everything above it square, dry, and stable. Tri-County Construction pours concrete foundations across Delaware for additions, garages, sheds, pole buildings, accessory structures, and light commercial work. That can mean continuous footings, slab-on-grade, footing and stem wall systems, basement walls, or repair and replacement when an existing foundation is failing.

Every project starts with code and site conditions. Footings go below Delaware frost depth, rebar is tied to engineered specifications, and inspection timing is coordinated before the next phase covers the work. Builders and homeowners call us when they need a concrete crew that understands the difference between a flat slab and a structural foundation with sign-off requirements.

Slab-on-grade can be the right call for a simple structure, while footing and stem wall systems give you more options for drainage, finished space, and long-term structure support. Winter pours are possible with cold-weather additives and curing blankets, but they require a tighter plan and more cure time. We give you that plan before the first form is set.
