Settled slab pulling your floors and doors out of shape? We lift it back to level without tearing it out - and we fix the soil cause so it stays that way.
Foundation raising in Rialto lifts a sunken or uneven concrete slab back to its original level position by pumping material beneath it to fill voids and push the concrete up - most jobs are completed in a single visit, often in just a few hours, with the surface usable again the same day.
Most Rialto homeowners reach out when they notice sticking doors, sloped floors, or widening cracks in a driveway or patio. Those symptoms almost always trace back to the clay-heavy soil beneath the Inland Empire - soil that swells when wet and pulls away from slabs during the long dry summers. Foundation raising addresses the concrete you can see, but a trustworthy contractor will also explain what caused the movement before a single hole is drilled.
When an existing slab is too far gone to lift - crumbling, broken into pieces, or badly deteriorated - homeowners often ask about slab foundation building as the next step, since a full pour is sometimes the more cost-effective long-term solution.
When a slab shifts, door frames and window frames shift with it - and doors that used to swing freely start catching on the floor or frame. This is one of the earliest and most reliable signs that something has moved beneath your home. In Rialto, this often shows up after a dry summer when the clay soil has contracted and pulled away from the foundation.
Hairline cracks in concrete are common and not always serious, but cracks that are widening, stepping up or down on one side, or running diagonally across a slab are signs of uneven settling. Rialto homeowners often notice these after a wet winter, when rain saturates the clay soil unevenly and causes sections of a slab to drop at different rates.
Walk slowly across your living room or hallway in bare feet - if the floor feels like it tilts in one direction or has a soft spot, the slab beneath it may have dropped. This is especially common in older Rialto homes where the original soil compaction was not as thorough as modern standards require.
If you notice a gap forming where your baseboard meets the floor, or where the wall meets the ceiling in a corner, the structure is telling you something has moved. These gaps are not cosmetic - they are a sign that different parts of your home are no longer sitting at the same level, and waiting typically makes the gap wider.
We offer both mudjacking and polyurethane foam injection, and we match the method to your specific situation - the size of the sunken area, the soil conditions beneath the slab, how far it has dropped, and what the surface will be used for after the work is done. Mudjacking uses a cement-and-soil slurry and tends to cost less upfront. Foam lifting uses a lighter, water-resistant material that cures in about 15 minutes and works especially well in Rialto's clay-heavy soil where added weight on the ground is a concern. Both methods include soil cause assessment, hole patching, and full cleanup before we leave.
Homeowners whose foundation movement has caused concrete sections to crack beyond repair sometimes ask about concrete cutting as a companion service - removing the damaged panel cleanly before a replacement pour, so the surrounding concrete stays intact.
Suits homeowners with large sunken areas - driveways, patios, garage floors - where cost is the primary concern and same-day traffic is not required.
Suits homeowners who need fast curing, have Rialto clay soil concerns, or whose slab is in a high-use area like a driveway or walkway that needs to be usable the same afternoon.
Suits homeowners where the visible problem is a slab crack or soft spot caused by a void beneath the concrete rather than simple settling - the void is filled before any lifting begins.
Rialto sits on the valley floor of the Inland Empire, where the soil contains a high amount of clay. Clay soil is reactive - it swells when it absorbs rainwater and shrinks when it dries out. Summer temperatures in Rialto regularly exceed 100 degrees Fahrenheit, which pulls moisture from the ground quickly. The result is a soil that is in constant slow motion beneath any concrete slab sitting on top of it. Most of Rialto's housing stock was built between the 1950s and 1980s, meaning slabs have been going through this cycle for 40 to 70 years. That is enough cycles to create real voids and real settling. The problem is not unique to any one neighborhood - we see it from the streets near downtown out to the newer sections closer to the 210 Freeway.
The seismic activity in the San Bernardino Valley adds to this. Rialto sits in a region crossed by several active fault systems, and even minor shaking can accelerate soil movement around an already-unsettled slab. We work throughout Rialto and extend into neighboring Fontana, where the same soil and climate conditions drive the same foundation settling problems. The FEMA Foundation Inspection Guide is a useful reference if you want to understand what signs to look for before calling a contractor. For permit questions specific to Rialto, the City of Rialto Building and Safety Division handles all foundation-related permit inquiries.
When you call, you describe what you have been noticing - uneven floors, sticking doors, visible cracks - and we schedule a time to look at the property in person. Most residential foundation work includes a free estimate visit, so there is no cost just to have someone come out and assess.
We walk the affected areas with you, look at the cracks and uneven spots, and assess what is happening beneath the surface. We explain what we think caused the problem - not just what we plan to do about it - and give you a written estimate before any work is scheduled.
Before the work day, you clear the area - move cars from the driveway, take furniture off a patio, or clear stored items from a garage floor. The crew arrives with a pump truck, drills small holes through the slab, and pumps material through them until the surface rises back to level. Most jobs are done in a few hours.
Once the slab is level, the crew fills and patches the drilled holes and cleans the work area before leaving. If foam was used, you can walk on the surface within 15 to 30 minutes. Mudjacking needs about 24 hours. We will tell you what to watch for in the months ahead based on your soil conditions.
No obligation. We come to your property, explain exactly what we see, and give you a written quote before any work is scheduled. We reply within 1 business day.
(909) 546-5589Rialto's clay soil shifts with every dry summer and wet winter, and lifting a slab without understanding what caused it to drop is like patching a leak without finding the pipe. We explain the cause before any work begins, so you are not paying to fix the same problem twice.
The City of Rialto has its own building and safety requirements, and navigating them on your own is time-consuming. We handle the permit process from start to finish so the work is documented, inspected, and on record - which matters if you ever refinance or sell your home.
We have been lifting and releveling concrete foundations throughout Rialto and the surrounding Inland Empire since 2023. We know the clay soil conditions in this area, the local permit office, and what causes slabs to settle in Rialto's seasonal climate.
One of the biggest fears homeowners have is watching a job expand in cost once work has started. We assess your situation in person before quoting, and we do not begin any lifting until you have a written estimate in hand. The price you agree to is the price on the final invoice.
Every foundation raising job in Rialto starts with the same question: why did this slab settle? The answer shapes everything that follows - the method, the depth, and whether any drainage or soil work needs to happen alongside the lift. That diagnostic step is what separates a lasting repair from one you will be calling about again next summer.
