What to know
Foundations built for Solano County soil
Much of Solano County sits on expansive clay soils that shrink and swell with the season, drying and cracking in Fairfield's hot summers and expanding again with winter rain. A foundation that is not prepped and reinforced for that movement is the most common source of long-term cracking and settling problems. We build to the soil conditions on your site, not a one-size-fits-all approach.
What a proper foundation install includes
- Excavation to the depth specified by the plans or a soils engineer
- Compacted aggregate base and a vapor barrier where called for
- Steel rebar or wire mesh reinforcement sized to the expected load
- Precise forming to the plan's elevations and dimensions
- Inspection before the pour on permitted jobs
- The pour itself, followed by proper cure time before framing begins
How much does a concrete foundation cost in Fairfield?
Pricing depends on the foundation's size, soil conditions, engineering requirements, and how much excavation and rebar the job calls for. We review your plans and site, then provide a free, written, itemized estimate before any work begins. Call (707) 880-2101 to schedule a visit.
Permits, engineering & inspection
New foundations, additions, and ADU foundations typically require a permit, engineered plans, and at least one inspection before the pour. We work from your stamped plans and coordinate the inspection schedule so it does not hold up the project.
ADU, garage & shed foundations
Whether it is a simple slab for a storage shed or a fully engineered ADU foundation with footings and stem walls, we pour to the plans provided and to code, so the structure above it is supported the way it is designed to be.
