Foundations are the most consequential concrete work on any property — get them wrong and everything above suffers. Concrete Charleston pours residential and light-commercial foundations engineered for Lowcountry soil and climate conditions.
From monolithic slabs and stem walls to footings and crawlspace foundations, we deliver foundations that meet code, pass inspection, and support the building above without movement or cracking.
Foundation Types We Pour
Monolithic Slab Foundations
A single pour combining footing and slab — efficient and common for additions, garages, and smaller structures.
Stem Wall Foundations
Concrete footings with block or poured walls bringing the slab above grade — critical in flood-prone Charleston neighborhoods.
Footings and Pier Foundations
For elevated structures, decks, additions, and outbuildings. We dig, set rebar, and pour to engineered specs.
Crawlspace Foundations
Common in historic Charleston construction. We pour footings and walls that match existing structures.
Why Foundation Quality Matters in Charleston
Our soil is sandy, our water table is high, and our climate cycles between humid heat and the occasional freeze. Foundations here have to handle all of it — and the only way to do that is proper site prep, proper rebar, proper concrete mix, and proper cure.
Site Evaluation
We assess soil conditions, drainage, and grade before any concrete is ordered. A foundation poured on the wrong sub-base is a foundation that will fail.
Engineered Reinforcement
Rebar sizing and spacing per spec or engineer’s drawings. No shortcuts.
Permits and Inspections
We pull permits where required and coordinate inspections. Charleston-area codes vary by jurisdiction — we know the differences.
Our Foundation Process
Layout and Excavation
String lines, batter boards, and excavation to the right depth.
Forming and Rebar
Form panels set true, rebar tied to spec.
Pour and Finish
We pour with the right slump and finish appropriate to the foundation type.
Cure and Strip
Proper cure time before any load is applied. We don’t rush concrete.
