Cracked surface, poor drainage, or starting from scratch? We build concrete parking lots in Pomona that are properly permitted, drained for clay soil, and built to hold up through Southern California heat and rain cycles.
Concrete parking lot building in Pomona covers everything from demolishing an old cracked surface to pouring a new lot on bare ground - most residential and small commercial jobs take three to five days of active work, with a one-week wait before foot traffic and four weeks before regular vehicle loads. The City of Pomona requires a grading permit and, for larger lots, a building permit with a stormwater runoff plan before construction can begin.
The Inland Empire climate - long dry summers followed by concentrated winter rains - creates a tough cycle for any paved surface. Concrete holds up significantly better than asphalt in this environment because it does not soften in the heat and it handles drainage slope better when properly installed. A well-built lot here should last 25 to 40 years with basic maintenance, compared to 10 to 15 years for asphalt before major resurfacing is needed.
If your project also needs structural concrete work beneath the lot, our concrete footings service covers the below-grade support work for any garages, carports, or structures going in alongside the lot.
Small hairline cracks at the edges of a lot are normal over time, but cracks that run across the middle of the slab - especially ones wide enough to catch a coin - mean the base underneath has shifted or failed. In Pomona, clay soil expanding and contracting through wet and dry seasons is the most common cause. Patching is a short-term fix at this stage; a full replacement is the more honest answer.
Puddles that sit for hours in the same spots after a rainstorm mean the surface has lost its drainage slope or the base has settled unevenly. Standing water weakens the base and accelerates cracking, and in Pomona's winter rain season this kind of pooling can cause significant damage within a few years. Poor drainage is the single biggest cause of early parking lot failure here.
When the top layer of concrete breaks into small chunks or looks sandblasted, the concrete has reached the end of its useful life. This kind of surface deterioration is also a safety issue - it creates uneven footing and can damage vehicle tires. Resurfacing alone rarely holds at this stage; a full replacement gives you a clean, safe surface that will last another 25 to 40 years.
Pomona has a significant urban tree canopy, and mature trees near parking areas are a common cause of slab heaving - where sections of concrete are pushed up from below by growing roots. If you can see sections that are noticeably higher than the surrounding surface, or feel a bump when you drive over a spot, root intrusion is often the cause. Patching over roots is not a lasting fix; the affected sections need to be removed and repoured.
We handle new concrete parking lot construction for residential properties, small commercial sites, and multi-unit buildings across Pomona. Every project starts with a site visit to assess the existing surface, the slope for drainage, soil conditions, and any access issues. We then design the base thickness, joint layout, and drainage plan for that specific lot - not a copied template. For properties that also need a driveway connection to the street, we coordinate our concrete driveway building work as part of the same project, keeping the pour consistent and reducing total mobilization time.
We also do full replacement of deteriorated lots - ones that have failed bases, major cracking, or root damage from mature trees. Replacement work includes demolishing and hauling away the old concrete, evaluating and rebuilding the base if needed, and addressing any drainage or root issues before the new pour. For projects where structural concrete footings are required for an adjacent structure, we handle that work in the same mobilization to keep your timeline on track.
Ideal for properties adding commercial use, a garage, or additional parking to meet city requirements.
Best for lots with failed bases, extensive cracking, or root heaving that patching cannot fix.
Suited for projects where the lot and street-access driveway need to be poured consistently in one scope.
Pomona sits on clay-heavy soil that swells with winter rain and shrinks back in the summer heat - a cycle that puts stress on any paved surface from below. A lot of Pomona's commercial and residential properties also have older base layers built to 1950s and 1960s standards. When replacing an existing lot, that old base often needs to be rebuilt from scratch, not just poured over. Contractors who skip that step save time upfront and create cracking problems within a few years. The American Concrete Institute publishes the base preparation and joint spacing standards that govern how lots like these are built correctly.
Pomona's stormwater rules add a real step to the permitting process that out-of-area contractors sometimes miss. The city falls under the Los Angeles County stormwater permit system, which means any new paved surface above a certain size needs a runoff management plan - not just a pour permit. We know what Pomona's Public Works Department needs to see and include that in the permit drawings from the start. We serve property owners across Pomona and nearby cities, including clients in Ontario and Riverside, where similar soil and drainage conditions apply across the Inland Valley.
We respond within 1 business day to schedule a free on-site visit. Parking lot pricing depends on size, site conditions, and existing surface - a phone quote is not reliable for a job this size. Expect the site visit to take 30 to 45 minutes.
After the site visit you receive a written estimate that separates demolition, base preparation, the pour, and any drainage work. We tell you upfront which permits Pomona requires for your project and include permit fees in the estimate so there are no surprises.
Once you approve the estimate, we apply for the required permits through the City of Pomona. Depending on project size and current city workload, this can take a few days to a few weeks. You do not need to visit the permit office - we handle it.
The crew removes any existing pavement, grades the ground for drainage, and compacts a gravel base before pouring the concrete. The base preparation step is the most important part of the job. Control joints are cut at regular intervals on the same day as the pour.

(909) 868-1669We hold a current California Contractors State License Board C-8 Concrete license - check it at cslb.ca.gov anytime. Full liability and workers compensation coverage means you carry no risk if something unexpected happens during demolition or base work.
Pomona falls under Los Angeles County's stormwater permit, which means new paved surfaces above a certain size must include a runoff management plan. We design every lot with the drainage slope and inlet placement the city needs to see - not as an add-on, but as a standard part of the job.
Concrete parking lots in Southern California outlast asphalt by two to three times because concrete does not soften in 95-degree heat the way asphalt does. The higher upfront cost typically pays for itself within the first maintenance cycle - you are not resurfacing every decade.
You receive a full, itemized written estimate - demolition, base prep, concrete, drainage, and permit fees - before any agreement is signed. No price changes once the crew shows up. We follow the concrete mix and joint spacing standards published by the American Concrete Institute.
Every parking lot project we complete is fully licensed, permitted to Pomona's current stormwater and grading standards, and built with the base compaction that clay soil in the Inland Empire actually demands. We have worked on residential lots, small commercial properties, and multi-unit sites across Pomona and the surrounding region.
Verify any concrete contractor's California license at cslb.ca.gov before signing any contract. Pomona's permit and stormwater requirements for paved surfaces are administered by the City of Pomona Public Works Department.
