UCM Upland Concrete Masters is a licensed Concrete Contractor serving Ontario, CA with concrete floor installation, driveway building, and patio construction - and we have completed jobs throughout this city since 2024. We know Ontario's mix of aging ranch homes near Euclid Avenue and newer subdivisions on the south side, and we account for the expansive clay soils that crack slabs across the Inland Empire.
Many Ontario garages and utility spaces were built in the 1960s and 1970s with thinner slabs that are now cracking from decades of soil movement beneath them. We pour properly reinforced floors with the right base preparation for local clay soils, so you are not dealing with the same heaving and cracking again in five years. See more about our concrete floor installation services.
Ontario's mid-century ranch homes on the north side of the city sit on expansive soils that crack driveways from underneath - patching only delays the inevitable. We replace failing slabs and build new driveways with the gravel base and slab thickness needed to handle the wet-dry soil cycles that are normal across this part of San Bernardino County.
Ontario's warm evenings and long outdoor season make backyard space worth investing in, but clay soil and heat cycles are hard on patios that were not built with local conditions in mind. We pour patios with the right slope, base depth, and reinforcement to stay level and crack-free through years of Inland Empire summers.
Ontario has a large base of industrial and commercial properties near the airport and along major freight corridors, and many of these sites need parking surfaces that can handle heavy vehicles without breaking down in the heat. We build commercial-grade concrete parking lots with the thickness and joint spacing that industrial and warehouse properties here require.
Sloped lots and grade changes are common in Ontario neighborhoods near the foothills, and an old or undersized retaining wall can fail quickly when heavy winter rain saturates the soil behind it. We build structural concrete retaining walls sized for the grade and soil load on your specific property.
Newer Ontario subdivisions on the south and east sides of the city often have HOA guidelines that restrict loose-paver materials - stamped concrete gives homeowners a stone or brick look in one solid slab, with no joints to shift or weeds to grow through, and it meets most HOA surface requirements without added maintenance.
Ontario covers a wide range of housing ages, from Craftsman bungalows near historic Euclid Avenue built in the 1920s and 1930s, through the postwar ranch homes that fill the city's mid-section, to the newer two-story subdivisions on the south and east edges built in the 1990s and 2000s. Each era has different concrete needs - older homes often have original slabs that are long past their service life, while newer homes are now hitting the 20- to 30-year mark where driveways and patios start showing real wear. A contractor who understands this range knows what to look for at a site visit and will not treat a 1965 garage floor the same as a 2005 driveway.
Ontario's Inland Empire location means summer temperatures that regularly hit 100 degrees or above, and an underlying clay soil that expands with winter rain and shrinks during the long dry season. That annual movement is the main reason concrete cracks here, and it cannot be addressed with patching alone. The City of Ontario Building and Safety Division requires permits for most flatwork, and newer HOA-governed neighborhoods on the south side add a layer of review on top of city requirements. A contractor familiar with Ontario handles both as a standard part of the job.
Our crew works throughout Ontario regularly and pulls permits from the City of Ontario Building and Safety Division for flatwork, garage floors, and parking lot projects across the city. We understand the permit timelines there and how the inspection process works for different project types, which means fewer scheduling surprises for you.
Ontario is a city of distinct parts. The neighborhoods near Euclid Avenue - that historic boulevard lined with pepper trees in the center of the city - are among the oldest, with homes built before World War II sitting on original slabs. The neighborhoods near Ontario Mills and the newer developments off the 10 freeway are a different conversation entirely. We have worked in both parts and know what each one typically needs from a concrete contractor.
We also serve homeowners in nearby Chino and throughout Rancho Cucamonga, so if you have family or neighbors in either city who need concrete work, we can help them too.
We respond to all estimate requests within one business day. You will speak with someone who knows Ontario, and we will schedule a free on-site visit to measure the space and look at the ground conditions - no pricing over the phone without seeing the job first.
We assess the soil, check for drainage issues, and look at any existing concrete being replaced. You will receive an itemized written quote that covers demolition, base preparation, the pour, permits, and cleanup - no single-line estimates. This is also where we address cost questions directly so there are no surprises later.
We handle the permit application with the City of Ontario - you do not need to visit the permit office. Once the permit is approved, usually within a few business days to two weeks, we schedule your start date and confirm the crew and materials.
The crew handles demolition, base prep, the pour, and finishing. We coordinate the city inspection and walk you through the finished surface before we leave. You get care instructions, including the curing timeline for foot traffic and vehicles, so nothing is ambiguous.
We serve all of Ontario, CA - from the historic neighborhoods near Euclid Avenue to the newer developments on the south side. Call or fill out the form and we will get back to you within one business day.
(213) 836-7114Ontario is a city of about 185,000 people in San Bernardino County, roughly 35 miles east of downtown Los Angeles. It is one of the larger cities in the Inland Empire, and its housing stock reflects that growth - older Craftsman and Spanish Colonial Revival homes sit near downtown and along the Euclid Avenue corridor, while the southern and eastern edges of the city are filled with the two-story stucco subdivisions built during the 1990s and 2000s suburban expansion. Many of those newer homes are now 20 to 30 years old, which puts their driveways, patios, and garage floors right in the age range where concrete starts needing real attention. You can learn more about Ontario's history and neighborhoods through the Wikipedia article on Ontario, California.
Ontario International Airport anchors the city economically and gives it one of the most recognizable addresses in the Inland Empire. The surrounding warehouse and distribution network - with major operations near the 10 and 15 freeways - means the city handles heavy commercial traffic that also drives demand for commercial concrete work. On the residential side, we serve homeowners across the full range of Ontario neighborhoods, from the streets near the airport to the quieter blocks on the north side. We also work regularly in neighboring Montclair to the east and Chino to the south, so if you know someone in either city who needs concrete work, we cover those areas too.
