Engineered foundations for expansive clay
Sacramento-metro specialty
About this service
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.
Working in Folsom
Every Sacramentoneighborhood has its own soil, drainage, and permitting realities. Here's what we've learned pouring concrete in Folsom.
Folsom sits on granite foothills — generally excellent sub-base for concrete, with decomposed granite providing natural drainage. The catch is older Empire Ranch and Briggs Ranch lots that were cut into hillsides; those have engineered fill that needs proper compaction verification before any structural slab. We core-test sub-grade compaction on retaining walls and ADU pads as a matter of course.
Folsom's Community Development department handles concrete-related permits. Folsom HOAs — particularly Empire Ranch, Russell Ranch, and Lexington Hills — are strict about visible finish, color tone, and decorative patterns. We submit material samples for ACR approval whenever a job is in HOA territory. Folsom Lake's defined-property-line setbacks add a wrinkle for lakefront work that we handle from the start.
Steep-driveway and hillside-pour work is a Folsom specialty for us — formed with proper rebar and engineered cross-fall for water. Stamped patios and outdoor kitchens are heavy in the Empire Ranch and Lexington Hills custom-home market. We also pour ADU foundations regularly on the older Folsom lots where the new-build density is climbing.

What's Included
These are the specifications and details we build in by default. Not upgrades. Not extras. Standard scope on every project.
Every foundation pour is built to a stamped structural drawing — yours, your architect's, or a referral to one of three Sacramento-area structural engineers we work with regularly.
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.
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.
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.
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.
All anchor bolts and seismic hold-down hardware embedded per the structural drawings, with locations verified before the pour. No coring after the fact.
Our Process
Review the structural drawings and any soils report. Identify any conflicts, missing details, or items the inspector will flag. Refer to a structural engineer if drawings are needed.
Excavate to required depth, over-excavate expansive clay sections, replace with engineered fill, compact to spec, and stage for the pre-pour inspection.
Set forms, install vapor barrier, tie rebar to drawings, place anchor bolts and hold-down hardware per layout. Pre-pour inspection scheduled and walked.
Concrete placed to spec PSI, field cylinders cast, slab finished per drawings. Wet cure or curing compound applied per ACI guidance.
Forms stripped at 24–48 hours. 7-day and 28-day cylinder breaks tested. Final structural inspection scheduled and walked. Reports delivered.
