Whittier Concrete Company provides concrete contractor services in Pomona, CA, including slab foundation building, concrete driveways, and patio construction. We have completed jobs throughout this city, and every project is permitted and built with proper base preparation for the clay soils that cause early cracking on older Pomona slabs. Free written estimates, no obligation.
Pomona homeowners adding ADUs, garages, or room additions need a slab foundation that can handle the city's clay soils without cracking in the first few years. Our slab foundation building service includes soil compaction, a gravel base layer, steel reinforcement, and a pour built to current California seismic code - not the thinner slabs that were standard when most of Pomona was first built.
Many driveways in Pomona's older neighborhoods were poured without a proper base layer, straight onto compacted clay. When that clay swells through wet winters and dries out in hot summers - which Pomona definitely gets - the driveway heaves and cracks within a decade or two. Replacing the slab with proper base prep stops that cycle from repeating.
Pomona's inland climate means outdoor living is realistic from March through November. Most lots in the city are modest in size - 5,000 to 7,000 square feet - and a clean concrete patio makes usable outdoor space where a cracked slab or bare dirt currently sits.
Pomona has a mix of flat and gently sloped lots, particularly in neighborhoods near the foothills. A concrete retaining wall holds soil in place during the heavy rain events that occasionally hit this part of the San Gabriel Valley, and it creates level usable yard space that would otherwise erode.
Sidewalks on Pomona's older residential streets get pushed up by tree roots and cracked by soil movement over time. Lifted and cracked sidewalk slabs along the public right-of-way can create liability for the adjacent homeowner and often require city notification before repair work can begin.
A significant share of Pomona's housing was built between 1940 and 1970 - ranch-style and bungalow homes on lots that were considered generous at the time but are now tight by modern standards. The concrete poured during that era was thinner, lacked steel reinforcement in many cases, and sat directly on clay soil with no gravel base below it. The city sits at the eastern end of the San Gabriel Valley where the climate is noticeably hotter and drier than coastal parts of Los Angeles County - summer heat regularly exceeds 100 degrees - and that heat-to-cool cycling stresses older concrete that was never sealed or maintained. The result is that most of Pomona's original concrete - driveways, patios, walkways, and slab foundations - is cracked, uneven, or failing.
Pomona also sits close to the Pomona Fault and other seismic features of the eastern San Gabriel Valley, which means California's building code requires specific reinforcement details for any new foundation work in the city. That is not just paperwork - it is the difference between a slab that survives a moderate earthquake intact and one that cracks through. Homeowners in Pomona need a contractor who is current on local seismic requirements, familiar with the clay soil conditions that run through the city, and experienced enough to prepare a base correctly before the pour rather than skipping steps to win a lower-price bidding war.
We pull permits through the City of Pomona Building and Safety Division for every residential concrete project that requires one - slab foundations, retaining walls, and driveway replacements all require permits here. We know what the city asks for during plan check and inspections, and we do not take shortcuts that create problems when the inspector arrives.
Pomona sits where the 10, 60, and 71 freeways converge at the eastern end of Los Angeles County - it is a genuinely well-connected city, which makes scheduling and logistics straightforward. Residential work tends to be concentrated in the neighborhoods around Lincoln Park, near Cal Poly Pomona on the eastern side of the city, and along the streets surrounding the Fairplex fairgrounds. Whether your home is in one of the older central neighborhoods or in the newer areas closer to Diamond Bar, we serve all of Pomona.
We also work regularly in Ontario to the east and West Covina to the west. These neighboring cities share Pomona's Inland Valley climate and similar mid-century housing stock, so the approach to base preparation and reinforcement is consistent across all three.
We respond within 1 business day and schedule a free on-site visit. We do not quote foundation or slab work over the phone - soil conditions and site access vary too much across Pomona properties for a phone number to be useful.
We visit the site, evaluate soil conditions and drainage, measure the work area, and provide a written itemized estimate. The quote covers demolition if needed, soil compaction, gravel base, reinforcement, the pour, and permit fees - no hidden costs added later.
We handle the permit application with the City of Pomona. Once approved - usually within a few business days - we confirm your start date. You do not need to manage the permit process; that is our job.
The crew handles all stages - grading, forming, pouring, finishing. Active work typically runs two to five days depending on scope. After curing, the city inspector signs off, and we walk you through the completed project before closing out.
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 at your Pomona property. You will have a written quote before any work begins.

Pomona is one of the larger cities in the San Gabriel Valley, covering about 23 square miles with a population of over 150,000 residents. It sits at the eastern edge of Los Angeles County, bordered by Ontario to the east, Chino to the south, Diamond Bar to the southeast, and Claremont to the north. The city is best known regionally for the Fairplex - home of the Los Angeles County Fair - and for Cal Poly Pomona on the city's eastern edge. The 10, 60, and 71 freeways all converge in or near Pomona, making it a central hub for the eastern San Gabriel Valley and western Inland Empire.
The residential side of the city is dominated by mid-century single-family homes, concentrated in neighborhoods like Lincoln Park in central Pomona - one of the most intact historic residential areas in the Inland Valley, with Victorian and Craftsman homes dating back to the late 1800s. The broader city has a mix of 1940s through 1960s ranch homes on modest lots and duplexes mixed into older residential streets. About half of Pomona households are owner-occupied, and those homeowners tend to be practical about maintenance and improvements. Nearby cities we also serve include Ontario to the east and Compton to the southwest, both cities where older housing stock and challenging soils drive steady demand for quality concrete work.
