A new structure is only as good as the foundation underneath it. We install concrete foundations in Chino built to California's seismic standards, with full permit handling so your project is documented from day one.

Foundation installation in Chino covers the complete process from site preparation through a city-inspected, cured concrete base - most residential projects take one to three weeks from permit approval to a slab ready for framing. Everything above your floor depends on what is below it, and the steps that matter most - soil compaction, steel placement, and curing management - are the ones that are hardest to see once the concrete is poured.
Chino's combination of clay soils, summer heat, and seismic zone requirements makes foundation work here more demanding than in many parts of the country. PSB Chino Concrete Works handles every phase, including the permit application and both required city inspections. If your project also needs a concrete parking area or flatwork alongside the foundation, we handle both scopes on a single schedule.
Cracks that start at the corners of door frames or windows and run diagonally across the wall are often a sign the foundation beneath that area has shifted. In Chino, this pattern is especially common in homes built on clay-heavy soil, where seasonal wet-dry cycles cause the ground to move. A crack wide enough to fit a quarter is worth having a professional look at.
When a foundation settles unevenly, door and window frames go slightly out of square. A door that used to close easily but now drags on the floor or fails to latch - with no recent plumbing leaks or water damage - often points to movement at the foundation level. This is one of the earliest reliable signs that something is changing below the floor.
Walk slowly across your floors and pay attention to any area that tilts or dips. In Chino homes built on expansive clay, uneven floors often develop gradually over years as the soil beneath shifts through wet and dry seasons. A marble that rolls consistently in one direction is a simple way to check.
Any ADU, garage, room addition, or permanent outbuilding in Chino requires a new foundation before framing begins. California law and the City of Chino's building code both require permitted foundation work for any new habitable or attached structure. Starting without it creates serious problems at resale.
We manage the entire scope: permit application with the City of Chino Building Division, site excavation, soil grading and compaction, gravel base installation, moisture barrier, steel reinforcement placement, the concrete pour, and curing management. Both required city inspections - before the pour and at completion - are scheduled on your behalf. The signed permit record is yours at closeout, and you will need it when you sell the home. For clients who also need flatwork around the new structure, our slab foundation building service can be scoped together with adjacent concrete work in a single project.
We install foundations for accessory dwelling units, room additions, detached garages, and full new residential structures. California's current ADU laws have made foundation installation one of the most common projects we handle in Chino - many homeowners are converting garages or adding backyard units, and every one of those projects starts here. The California Department of Housing and Community Development publishes the standards that govern ADU foundation requirements statewide.
For home additions, ADUs, and new builds - full permit and inspection management included.
For attached or detached garage projects where a new slab is needed before framing begins.
For ADUs and habitable additions where utility lines must be placed before the pour.
For older Chino structures where the existing foundation has failed due to original prep issues or soil movement.
Chino sits within an active seismic zone, and California requires foundations built here to include more steel reinforcement and specific engineering details compared to much of the country. That requirement is verified during the pre-pour city inspection - it is not left to the contractor's discretion. This is one legitimate reason foundation work in California costs more than national averages, and it is a real benefit: your structure is designed to handle the ground movement that is part of life in the Inland Empire. The California Geological Survey seismic hazard maps show that Chino falls within areas requiring this elevated standard.
The clay-heavy soil under much of Chino - especially in established neighborhoods and in newer developments like The Preserve - swells in wet winters and shrinks in dry summers. A foundation that ignores that cycle will show the stress within a few years. We work in Chino and throughout the western Inland Empire, including Ontario and San Bernardino, where the soil and seismic conditions are closely related.
We respond within 1 business day. We ask about your project type - ADU, addition, full build - and schedule a free on-site visit. No price is quoted over the phone because every lot in Chino has different soil and access conditions.
We visit your property, assess soil conditions and site access, discuss permit requirements with you, and review any plan drawings you have. You receive a written estimate covering excavation, permits, steel, the pour, and cleanup - before you commit to anything.
We submit the permit application to the City of Chino Building Division on your behalf. Approval typically takes a few business days to two weeks. We schedule both city inspections - pre-pour and final - and handle all communication with the building department.
Site prep and steel placement take two to five days. The city inspector signs off before any concrete is poured. The pour itself takes a few hours for a standard residential foundation, followed by at least seven days of curing. Final city inspection closes out the permit and you receive your documentation.
We respond within 1 business day - no obligation, no pressure. After you submit, someone from our office will call to schedule a free on-site visit and give you a detailed written quote.
(840) 200-1378We submit the City of Chino permit application, schedule both required city inspections, and deliver the signed documentation at project closeout. You never have to visit the building department or track down an inspector - we handle all of it as part of the job.
Most of the Inland Empire - including Chino - sits on expansive clay soil that moves with seasonal moisture. We have prepared and poured foundations across this region and know what the ground under Chino properties actually does over time. That local experience shapes how we prep every site.
Chino falls within a seismically active zone, and California requires specific reinforcement details that exceed national minimums. We build to those standards on every project. The city inspector verifies the steel before anything is poured - your foundation is checked by an independent party before it is buried.
We give you a detailed written estimate that covers excavation, soil prep, permits, steel, the pour, and cleanup before you sign anything. The number on your estimate is the number on your invoice. Chino's busy season in spring and fall means projects book out quickly, so reaching out early keeps your timeline intact.
Every foundation we install in Chino is permitted, inspected twice by the city, and built to California's seismic requirements - not just the local baseline. That means your structure starts on ground you can trust, and you have the documentation to prove it.
