Sunken slabs and uneven foundations are common on Chino Hills hillside lots. We lift settled concrete back to level quickly, without tearing out your yard.
Foundation raising in Chino Hills lifts sunken or uneven concrete slabs back to their original level by pumping material underneath through small drilled holes - most residential jobs are completed in a single day, and you can walk on the surface the same afternoon.
Chino Hills sits on expansive clay soils that swell and shrink with every wet-dry season, and hillside grading means water naturally runs toward foundations. Those conditions create voids under slabs faster than in flat, sandy-soil cities. If you have noticed doors sticking, gaps forming between your slab and the wall, or floors that feel slightly off, the slab may have dropped while the concrete itself is still in good shape. Foundation raising addresses the problem without the cost or disruption of full replacement.
For situations where the slab itself is damaged beyond lifting, we also handle slab foundation building from the ground up.
When the ground under your foundation shifts, the frame of your home can shift with it - even slightly. If a door that used to swing freely now drags on the floor or a window takes real effort to open, that is worth paying attention to. These are often the first visible signs that something has moved underneath the slab.
Walk the perimeter of your home and look where the concrete meets the house, a porch step, or a garage wall. A gap that was not there before - even a small one - means the slab has dropped away from the structure. In Chino Hills, this often appears after a dry summer when clay soil contracts and pulls away.
Place a marble on your floor and watch what it does. If it rolls consistently toward one side of the room, the floor - and the slab beneath it - may have settled unevenly. This is especially common in Chino Hills homes built on graded hillside lots where one side of the foundation sits on more compacted fill than the other.
After a winter rain, notice where water collects. If it consistently pools against the side of your house or near the base of a concrete slab, that water is soaking into the soil underneath. Over time, this erodes the support under the slab and leads to settling - a pattern that is especially common on hillside lots throughout Chino Hills.
We offer two primary lifting methods depending on the slab and soil conditions. Polyurethane foam injection uses smaller holes, cures in about 15 minutes, and is lighter on already-stressed soil - making it a strong fit for hillside lots. Traditional mudjacking uses a cement-based slurry pumped through larger holes and can cost less upfront, though it takes longer to cure. We assess each job individually and recommend the method that makes the most sense for your specific situation.
For larger structural projects, our foundation raising work connects naturally to concrete cutting when sections need to be removed before lifting, and to slab foundation building when the existing concrete is too compromised to save. We handle both, so you get a consistent crew across the full scope of the job.
Best for homeowners who want minimal disruption and a fast cure - especially on hillside lots with clay soil.
A cost-effective option for larger slab areas where longer cure time is acceptable.
Ideal when the root cause is a persistent drainage issue - lifting without fixing drainage means the slab can settle again.
For homeowners in Chino Hills HOA communities who need approvals and permit documentation before any work begins.
Chino Hills sits on the Puente Formation, a mix of clay-heavy soils that behave very differently from the sandy or rocky ground you find in other parts of Southern California. Clay expands when it absorbs water and shrinks when it dries - and in a region where summers are consistently hot and dry and winters can bring heavy rain, that push-and-pull is relentless. The hillside grading that defines so many Chino Hills neighborhoods adds to the challenge: water naturally runs toward foundations on sloped lots, quietly eroding the soil support underneath long before any visible settling appears on the surface. Homeowners in Chino Hills deal with this more often than they expect, especially in homes built on fill soil during the rapid development of the 1980s and 1990s.
The City of Chino Hills Building and Safety Division requires permits for structural foundation repairs depending on scope, and many neighborhoods are governed by HOAs that require written approval before exterior work begins. We handle the permit process and have worked in HOA communities throughout the city. Homeowners in nearby Norco face similar hillside soil conditions and reach out to us for the same reasons. If you are not sure whether your property qualifies for raising, we will walk the site with you and give you a straight answer - no pressure.
We will ask where the settling is, how long it has been happening, and whether you have noticed any cracks or sticking doors. We reply within 1 business day and most estimates are free.
We walk the affected area with you, measure how much the slab has dropped, check drainage patterns, and look for signs of what caused the movement. You get a written estimate before any work is scheduled.
If the scope requires a permit from the City of Chino Hills or HOA approval, we handle that before starting. This step adds a few days but protects you during any future sale or refinance.
The crew drills small holes, pumps material underneath, and monitors level continuously as the slab rises. Most jobs finish in a few hours, patch holes are filled, and the crew cleans up before leaving.
We offer free on-site estimates in Chino Hills. No pressure. We will tell you honestly whether raising is the right fix or whether something else makes more sense.
(909) 760-1029The expansive clay soils throughout Chino Hills require a different approach than flat-land projects. We assess drainage patterns and soil conditions as part of every estimate - not as an add-on - because fixing the slab without understanding why it settled is a short-term fix at best.
Many Chino Hills neighborhoods require permits and HOA approval before structural work begins. We manage both, so you are not chasing paperwork or risking a violation notice. That process is included in our project management, not billed separately.
We serve all 12 communities in our service area, from Chino Hills and Norco to Rancho Cucamonga and Corona. Crews are familiar with the terrain, soil types, and permit processes across the Inland Empire - not just in one zip code.
You get a written scope of work before any crew shows up. The method, area, and materials are all spelled out. If something unexpected comes up during the job, we discuss it with you before proceeding - not after.
Foundation raising is a job where local knowledge matters more than most people realize. A crew that understands hillside drainage, clay soil behavior, and City of Chino Hills permit requirements will deliver a result that holds - not one that looks good on day one and settles again by the following dry season. You can also verify our license through the California Contractors State License Board before you call.
