Serving Orange, CA and surrounding areas. (657) 333-3989

Orange Concrete Company is the concrete contractor Ontario, CA homeowners and property managers call for concrete parking lots, driveway replacement, and patio work. We have served Ontario since 2022, hold a current California contractor license, and pull all city permits in-house on every project.
Ontario's mix of residential properties, small commercial buildings, and multi-family rentals creates steady demand for new and replacement concrete parking surfaces. Many lots near downtown and the older ranch neighborhoods have asphalt or unpaved surfaces that are past the point where patching makes sense, and Ontario's clay soils and summer heat make concrete a better long-term choice than asphalt for any permanent surface. See our full concrete parking lot building service page for details on base preparation, drainage design, and the permit process.
Ontario's mid-century ranch homes from the 1960s and 1970s commonly have original concrete driveways that are showing the effects of decades of clay soil movement and summer heat. Cracks that start at control joints widen every wet season as the soil beneath expands and contracts. We replace full driveways with properly prepared bases and handle the city connection when the new driveway ties into a public curb approach, keeping all permits under one project.
Ontario's warm, dry climate makes outdoor space usable for most of the year, and a concrete patio is the practical foundation for a backyard that holds up to it. Flat lots in Ontario's residential neighborhoods can be slow to drain after winter rain, and a patio graded with a slight slope away from the house moves water off the surface rather than letting it sit against the foundation. We pour replacement patios and new additions on both older and newer homes across the city.
Properties near Ontario's older downtown neighborhoods sometimes have grade changes or sloped rear yards that need a wall to hold back soil. Ontario's clay soils expand with rain and shrink in summer, and a retaining wall without proper drainage behind it will eventually lean or crack from that pressure. We design drainage into every retaining wall we build so water has somewhere to go instead of pushing against the concrete.
New ADU construction, garage additions, and outbuildings on Ontario properties all start with a slab that has to sit on clay soil without shifting. We pour slab foundations with the base preparation and steel reinforcement that Ontario's soil conditions require, so the structure on top stays level through years of wet and dry cycles. For ADU projects, the permit process in Ontario requires the slab plan to be part of the overall building application.
Sidewalks on Ontario's established streets get pushed up by tree roots over time, and California property owners bear liability for tripping hazards on the public walkway fronting their lot. Panels lifted more than an inch are a real risk. We replace individual lifted panels or complete sidewalk runs and coordinate with the City of Ontario on any connection that ties into a public curb or driveway approach.
Ontario has been growing steadily for decades, which means its housing stock spans a wide range of ages and construction types. Near downtown and along Euclid Avenue, homes built in the 1920s through 1950s are common, many with stucco or wood-frame construction and original driveways and walkways that have been patched rather than replaced. Moving outward from the historic core, mid-century ranch homes from the 1960s and 1970s fill the middle neighborhoods, followed by planned subdivisions from the 1990s and 2000s on the southern and eastern edges of the city. Each era has its own concrete problems, but the soil and climate challenges are shared by all of them.
The clay-heavy soils across much of Ontario expand when winter rains arrive and contract sharply when summer dries them out. That cycle is the most common reason concrete driveways and patios crack in this city, and it is a problem that concrete thickness alone does not solve. The fix is in the base preparation: a properly compacted gravel layer under the slab absorbs the soil movement before it can push the concrete out of position. A contractor who skips or rushes this step to keep a bid competitive is transferring the cost to the homeowner in the form of early cracking.
Ontario's summers are genuinely hot, regularly topping 100 degrees Fahrenheit from June through September. That heat matters for concrete work because fresh concrete poured in extreme heat loses surface moisture faster than it should, which leads to surface cracking that is visible before the first year is out. Experienced contractors working in Ontario schedule pours for early morning and use curing compounds to slow that drying process down. Drainage is the other factor: Ontario averages only about 15 inches of rain per year, but the dry, compacted soil does not absorb it quickly when it does come. A surface graded without a proper drainage slope will hold water after winter storms, and standing water erodes the base underneath any concrete slab over time.
Orange Concrete Company has been filing permits through the City of Ontario Community Development Department on residential and small commercial concrete projects since 2022. Ontario requires permits for parking lot construction, driveway approaches connecting to public streets, and retaining walls above certain height thresholds. We handle the permit application, coordinate drainage and grading plan submissions when required, and schedule inspections so the city sign-off process does not hold up the homeowner's timeline.
We work throughout Ontario, from the older homes near Euclid Avenue downtown, where some of Ontario's earliest housing stock sits on narrow lots with original concrete, to the ranch-style neighborhoods in the city's middle and the newer subdivisions near Ontario International Airport and Ontario Mills on the south side. The Euclid Avenue corridor is listed on the National Register of Historic Places and the homes along it are among Ontario's oldest, which means their driveways and walkways often have more than 60 years of clay soil movement worked into them. The newer southern neighborhoods present a different set of conditions: stucco homes on larger lots with HOA requirements that govern what surface materials and finishes are acceptable.
We also serve neighboring Riverside and Pomona, and crews working regularly across the Inland Empire understand that the clay soils and summer heat in this part of the region require preparation steps that coastal jobs do not always demand.
Call or submit our contact form and we respond within 1 business day to set up a free on-site estimate. No finished plans needed before calling. We will assess the site conditions, measure the project area, and ask the right questions when we get there.
We check the soil and drainage, measure the project area, and assess whether an HOA approval or city permit is needed. The written quote breaks out demolition of the existing surface, base preparation, concrete, and any permit costs, so there are no line items that appear on the invoice but not in the estimate.
We file the city permit, remove the existing surface, and compact a gravel base before pouring. In Ontario's summer heat, we schedule pours for early morning and apply curing compound to keep surface moisture from escaping too quickly during the critical early hours after the pour.
After the concrete cures, we walk the finished surface with you and cover the drainage slope, control joints, and care instructions for your specific finish. For permitted work, we schedule and pass the city inspection before closing out the job.
We serve all of Ontario, from the historic neighborhoods near Euclid Avenue to the newer subdivisions on the south side near Ontario International Airport. Call today or fill out our form for a free, no-obligation estimate.
(657) 333-3989Ontario is a city of about 185,000 people in San Bernardino County, roughly 35 miles east of downtown Los Angeles in the heart of the Inland Empire. The city has a recognizable historic core centered on Euclid Avenue, a grand boulevard lined with a double row of pepper trees that runs through the center of the city and is listed on the National Register of Historic Places. The surrounding streets are some of Ontario's most established neighborhoods, with Craftsman bungalows and Spanish Colonial Revival homes built in the 1920s through 1950s side by side. Moving outward from that core, mid-century ranch homes from the 1960s and 1970s fill much of the city's middle, and then newer subdivisions from the 1990s and 2000s extend toward the south and east.
Ontario is also a major logistics hub, home to Ontario International Airport and a large network of warehouses and distribution centers. That industrial base means a large working and middle-income population of homeowners who want contractors who show up on time and get the job done without unnecessary back-and-forth. About half of Ontario's housing units are owner-occupied, giving a significant share of residents a direct financial stake in keeping their properties in good shape. Nearby Riverside and Pomona are neighboring cities we serve with the same crew and the same approach to inland concrete conditions.
The city's clay soils and hot summers mean concrete maintenance needs tend to arrive on an accelerated timeline compared to coastal cities. Driveways crack faster, drainage problems surface sooner after rainy winters, and parking surfaces on properties without adequate base preparation show wear well before their expected service life. Ontario homeowners who deal with these issues regularly are better served by a contractor who understands Inland Empire conditions than by one who primarily works closer to the coast.
