Engineered foundations for expansive clay
Sacramento's Trusted
Foundation Contractor Contractor
Sacramento sits on a basin of expansive clay soils that swell when wet and shrink hard when dry. Foundations that ignore that fact crack, settle differentially, and pull drywall apart at every interior corner. Foundations that respect it — proper depth, the right reinforcement, the right vapor barrier — last the life of the structure. We've poured residential foundations, ADU pads, and structural slabs across the Sacramento metro for 20 years and we've never had a single one fail a structural inspection.

About this service
Foundation Contractor done right in Sacramento, CA
Sacramento sits on a basin of expansive clay soils that swell when wet and shrink hard when dry. Foundations that ignore that fact crack, settle differentially, and pull drywall apart at every interior corner. Foundations that respect it — proper depth, the right reinforcement, the right vapor barrier — last the life of the structure. We've poured residential foundations, ADU pads, and structural slabs across the Sacramento metro for 20 years and we've never had a single one fail a structural inspection.
Every foundation we pour is engineered. We work from stamped structural drawings (we'll refer you to a structural engineer if you don't have one yet), we follow CRC and CBC requirements for the specific jurisdiction, and we pour to PSI specs verified with field cylinders and lab-tested 7- and 28-day breaks. The mix is right, the rebar is right, the depth is right, and the inspector signs off.
Foundation scope ranges from a 200 sq ft ADU pad to a full single-family residence with stem walls and pier-and-beam crawl space, to a structural slab pour for a new commercial tilt-up. We pull the permits, schedule the inspections, and stay on the job through the structural sign-off.
What's Included
Every foundation contractor we build includes
These are the specifications and details we build in by default. Not upgrades. Not extras. Standard scope on every project.
02
Clay-Aware Excavation
Expansive clay subgrades are over-excavated and replaced with engineered fill where soils reports require. We don't pour foundations directly on swelling native clay.
03
Proper Vapor Barrier
15-mil vapor barrier under all habitable slab-on-grade pours, lapped and sealed at seams, with penetration boots at every plumbing and conduit pass-through.
04
Tied Rebar, Not Walked-In
Reinforcement is tied off the slab on chairs and dobies before any concrete arrives. We never 'walk it in' — that's an instant inspection fail and a guaranteed weak spot.
05
Cylinder Testing on Every Pour
Field cylinders cast at every foundation pour, lab-tested at 7 and 28 days, report sent to the EOR and to you. Strength is documented, not assumed.
06
Anchor Bolts & Hold-Downs
All anchor bolts and seismic hold-down hardware embedded per the structural drawings, with locations verified before the pour. No coring after the fact.

Foundation Contractor FAQ
Common questions
Specific to foundation contractor in Sacramento, CA
Do you build foundations for ADUs in Sacramento?
Yes, ADU foundations are a meaningful part of our residential foundation work. We've poured pier-and-beam, slab-on-grade, and stem-wall ADU foundations across Sacramento, Elk Grove, Rancho Cordova, and the surrounding metro. We handle the permits and the inspections, working from your designer's or architect's structural drawings.
How deep does a foundation need to be in Sacramento?
Per the CBC and CRC as adopted by California jurisdictions, residential footings must extend at least 12 inches below natural grade and below the frost line (which in Sacramento is shallow — frost is rarely the controlling factor). For expansive clay soils, footings often need to extend 18–24 inches to reach stable material. The specific depth comes from your soils report and the structural engineer's design.
How long does a residential foundation take to pour?
From excavation to forms-off is typically 2–4 weeks for a standard single-family foundation, depending on size and weather. The pour itself is one day. Curing before framing can start is typically 7–14 days depending on size and reinforcement details. Permits and inspections add 1–3 weeks to either end depending on jurisdiction.
What's the difference between slab-on-grade and crawl space foundations?
Slab-on-grade is a single monolithic concrete slab that sits directly on the prepared sub-grade — the floor of the home is the foundation. Crawl space (or stem wall) construction places concrete stem walls around the perimeter with an open void underneath, with a wood-framed floor system above. Slabs are cheaper and faster; crawl spaces give access to plumbing and HVAC. Sacramento sees both — slabs are more common in newer construction.
Do you carry the insurance for foundation work?
Yes. $2M general liability, full California workers' compensation, and our license is endorsed for structural concrete. Certificates of insurance and license verification are provided at contract signing.
