Rialto Concrete and Masonry is a masonry contractor serving Ontario, CA with driveway paver installation, block wall repair and construction, and foundation work for homes across the city - and we have been working throughout the Inland Empire since 2020, handling jobs on everything from 1920s Craftsman bungalows near Euclid Avenue to newer stucco subdivisions on the south side of the city.

Ontario driveways take a beating. The city's clay soil shifts every wet season, and summer temperatures that routinely hit 100 degrees Fahrenheit cause poured concrete to crack faster than in cooler climates. Our driveway paver installation uses a properly engineered gravel base sized for Inland Empire soil conditions, so the surface handles seasonal movement instead of fighting it.
Mid-century ranch homes throughout central Ontario were built with block perimeter walls that are now 50 to 60 years old. Most of those original walls were built without the footing depth and core reinforcement that modern codes require, and the soil movement that comes with every rainy season has been working on them ever since. We rebuild leaning or cracked walls to current standards - not just patch them.
The older neighborhoods near Euclid Avenue and downtown Ontario include homes with foundations dating to the 1920s and 1930s, many of which have never been assessed. When clay soil swells after winter rain and dries through the long summer, the pressure on shallow foundations is real. We diagnose what is causing the movement before quoting a repair - so the fix addresses the actual cause, not just the visible crack.
Properties on the northern edges of Ontario that border Rancho Cucamonga often have slight grade changes that require drainage management. A retaining wall without a drainage system behind it will eventually bow from water pressure accumulating during winter rains. We design and build walls with built-in drainage so they hold long after the warranty on a cheaper job would have expired.
Spanish Colonial and Craftsman-era homes near Ontario's historic downtown often have original brick chimneys, planters, and entryway columns that have never been touched. Decades of Inland Empire heat cycles dry out mortar joints until they crumble, and once water gets in during a winter storm, the damage spreads fast. We match the original mortar profile and replace only what needs to go - not the whole structure.
Ontario homeowners near the older Euclid Avenue corridor often have front walkways that are original concrete - cracked, heaved, and uneven from decades of clay soil movement beneath. A trip hazard on the front path is a liability as well as an eyesore. We replace failing walkways with properly graded paver or concrete installations that drain away from the foundation instead of toward it.
Ontario's housing stock spans nearly a century of construction. The neighborhoods closest to historic Euclid Avenue and downtown include homes from the 1920s through the 1950s - Craftsman bungalows and Spanish Colonial Revival styles with original stucco, aging rooflines, and foundations that have been absorbing seasonal soil movement for 70 or 80 years. Moving outward, you find mid-century ranch homes from the 1960s and 1970s with block perimeter walls and concrete driveways that are reaching the end of their practical life. The southern and eastern parts of the city shifted to two-story stucco tract homes in the 1990s and 2000s, which are now 20 to 30 years old and entering the age range where exterior coatings, mortar joints, and concrete flatwork first start failing. Each era of construction responds differently to the same conditions - a contractor who does not ask how old your home is before quoting a job is missing information that directly affects what the right repair looks like.
The climate in Ontario adds pressure to every masonry surface on every home. Summer temperatures regularly hit 100 degrees Fahrenheit or above, which causes masonry materials to expand significantly during the day and contract overnight. That thermal cycling dries out mortar joints faster than in coastal cities and causes concrete slabs to develop stress fractures over time. Ontario's clay-heavy soil compounds the problem: it swells when the occasional winter storm arrives and shrinks back during the long dry stretch from May through November, putting upward and lateral pressure on everything it touches - driveways, walkways, block walls, and foundations included. Santa Ana wind events every fall regularly knock loose chimney caps and damaged block coping, and getting ahead of that damage before winter rains find the opening is almost always the cheaper path.
Our crew works throughout Ontario regularly, and we pull permits through the City of Ontario Planning and Building Safety Department for structural masonry jobs - including block walls and retaining walls that require seismic reinforcement per California standards. We know what the local inspectors look for, which means projects move through review without unnecessary delays.
We work across the full spread of Ontario's neighborhoods - from the historic streets near Euclid Avenue, where older homes sit on original foundations and have brick features that need careful matching work, to the newer subdivisions south of Ontario Mills along the 10 Freeway corridor, where two-story stucco homes are reaching the age where driveways, walkways, and exterior masonry first need attention. The city's large warehouse and distribution network near Ontario International Airport means heavy truck traffic on many surface streets, which adds wear to driveways and sidewalk-adjacent concrete faster than in quieter residential cities.
We also serve neighboring Montclair to the west, and homeowners in Rancho Cucamonga just to the north. If your project is close to a city boundary or a neighbor needs the same work done, we can often cover both properties on the same visit.
Reach out by phone or through the contact form. We respond within 1 business day and set up a time to visit the property - no commitment needed at this stage.
We walk the property, look at the soil, drainage, and existing masonry, and give you a written estimate that breaks out materials, labor, and any permit costs separately. We do not quote over the phone for structural jobs - Ontario's soil variation means footing requirements can differ from one street to the next.
We pull the required permits and schedule the crew around your availability. Active construction on a typical Ontario residential job runs two to four days. You do not need to be home the entire time, but we will walk you through the site at the start and end of each work day.
When the work is done, we walk the completed job with you, answer any questions, and clear all materials and debris from the property. If anything is not right, we address it before we leave.
We serve homeowners across Ontario, CA - from the historic neighborhoods near Euclid Avenue to the newer subdivisions near Ontario Mills. Call or send a message and we will get back to you within 1 business day.
(909) 546-5159Ontario is a city of roughly 185,000 people in San Bernardino County, sitting about 35 miles east of downtown Los Angeles in the heart of the Inland Empire. The city is defined in part by its historic layout: Euclid Avenue, a grand boulevard designed in the late 1800s and lined with a double row of pepper trees, runs through the center of the city and is listed on the National Register of Historic Places. The neighborhoods surrounding Euclid are among the oldest in Ontario, with homes from the 1920s through the 1950s that carry the marks of nearly a century of seasonal weather and soil movement. Moving outward in any direction, the housing transitions through mid-century ranch neighborhoods toward the newer stucco subdivisions that fill the southern and eastern edges of the city.
Ontario is also one of the busiest logistics hubs in the western United States. Ontario International Airport handles significant cargo volume, and the surrounding area is home to large distribution facilities operated by national carriers. That industrial activity keeps the local economy active and also contributes to heavy truck traffic on surface streets throughout the city. For homeowners, the practical effect is that driveways and concrete near high-traffic corridors often wear faster than in quieter residential cities. Neighboring Montclair borders Ontario to the west, sharing similar housing ages and soil conditions. To the north, Rancho Cucamonga picks up where Ontario leaves off, with its own mix of foothills neighborhoods and tract housing from the 1980s and 1990s.
