FMA Fontana Masonry is a licensed masonry contractor serving Rialto homeowners with foundation repair, concrete flatwork, and block wall work - free on-site estimates and a reply within 1 business day.

Rialto homes sit on concrete slabs over clay soil that has been expanding and contracting for 30 to 60 years. Our foundation repair work addresses cracks, settling, and instability at the source rather than just patching the surface.
Concrete driveways in Rialto crack and heave from clay soil movement and summer temperatures that climb above 100 degrees regularly. Paver installations absorb that movement at the joints rather than cracking through the surface, making them a longer-lasting option for this climate.
Block walls are the standard yard boundary in Rialto neighborhoods, and most homes from the 1960s through 1990s have them. After decades of clay soil shifting and Santa Ana winds, caps crack, mortar fails, and walls begin to lean. We repair and rebuild to current code.
Properties in Rialto with grade differences between lots or near drainage channels need retaining walls built to handle the clay soil's seasonal pressure. We design and build walls with proper drainage behind the face so water does not build up and push the wall over time.
Rialto properties typically have concrete walkways from the driveway to the front door and across the backyard. When clay soil heaves these surfaces, the result is trip hazards and uneven sections that only get worse. We replace cracked and sunken walkways with a properly prepared base that resists future movement.
Rialto was built fast. Most of the city's housing stock went up between the 1960s and 1990s as the Inland Empire expanded rapidly. That construction era means the vast majority of homes sit on concrete slab foundations - standard for Southern California - over soil that contains significant clay. Clay soil is the central challenge for masonry in Rialto: it absorbs water during winter rains and swells, then dries out and shrinks hard through the summer. That back-and-forth puts upward pressure on every concrete surface from below, year after year. By the time a Rialto slab has been through 30 or 40 of these cycles, cracks are not unusual - they are expected. The question is whether the cracks are cosmetic or structural.
Rialto's climate amplifies the problem. Summer temperatures regularly exceed 100 degrees Fahrenheit, which dries out mortar joints and caulk faster than in coastal cities and can cause concrete to expand and contract with each daily heat cycle. Fall Santa Ana winds knock loose chimney caps and blow debris across exposed masonry. The northern part of Rialto, closer to the 210 freeway corridor, has newer homes from the 1990s through 2010s with tile roofs and HOA-managed exterior standards - but the same underlying soil conditions. A contractor who applies coastal or inland-valley methods without accounting for Rialto's specific soil behavior tends to use base depths and materials that do not hold up here.
For structural masonry work in Rialto, we pull permits through the City of Rialto and know what the city's inspectors look for on final walkthrough. We work on the city's tract housing regularly - single-story homes with two-car garages, concrete driveways, and block wall fencing that are now 30 to 60 years old. These homes are at exactly the age where foundation cracks, failing driveways, and block wall repair calls become common.
Rialto sits between Fontana to the west and San Bernardino to the east, and the city is easy to navigate along the I-10 and 210 corridors. The flat grid layout means most neighborhoods are close together, and we move efficiently across the city whether we are working near Rialto Airport in the west or in the newer subdivisions up toward the 210. Eisenhower High School and Carter High School are landmarks most Rialto families know, and many of the neighborhoods around those schools have housing from the 1970s and 1980s that we see frequently.
We serve homeowners in nearby San Bernardino as well, and regularly handle jobs on properties that sit near the Rialto and San Bernardino city boundary. Reach out to confirm coverage if your project is near either city line.
We respond within 1 business day to schedule a free in-person estimate. No commitment required on the first call - just describe what you are seeing and we will set a time to come look at it.
We visit your property, assess the masonry in person, and give you a written estimate before any work begins. We explain what is causing the problem and what the repair will cost - in plain terms, not contractor jargon.
For structural work, we apply for the City of Rialto permit and coordinate the inspection schedule. We confirm your start date once the permit is in hand and materials are sourced - usually one to two weeks for most jobs.
Crew arrives on the agreed date, completes the work to the written scope, and cleans up before leaving. Permitted jobs receive a city inspector sign-off, and you get documentation of what was done.
We serve homeowners throughout Rialto, from the older streets near the city center to the newer neighborhoods up by the 210. Free on-site estimate, written quote, no pressure.
(909) 587-5725Rialto is a city of about 103,000 people in San Bernardino County, located between Fontana and San Bernardino along the I-10 corridor. The city was incorporated in 1911, but the bulk of its residential development came during the postwar suburban boom from the 1950s through the 1990s. That history gives Rialto a fairly uniform character across most neighborhoods: single-story and two-story tract homes, mostly stucco-finished, with concrete slab foundations, block wall fencing, and concrete driveways. Lot sizes are moderate by Southern California standards, typically 6,000 to 8,000 square feet, and most homes have a front yard, a backyard, and a two-car garage. The city follows a grid street pattern across a flat valley floor - which is one reason it expanded so quickly and why so many neighborhoods look similar to each other.

The northern part of Rialto, near the 210 freeway, has newer housing from the 1990s and 2000s with tile roofs and larger footprints. Those neighborhoods have different masonry needs than the older streets closer to downtown - newer homes need less foundation work but more flatwork replacement as their driveways and patios age through the 20-to-30-year mark. We work across both parts of the city and serve neighboring communities as well, including Fontana to the west.
