Our Concrete Leveling Services
Driveway Concrete Leveling
A sinking driveway creates low spots where water sits after every rain. It also forms uneven edges at the garage apron and at the street curb. Those transitions are tripping hazards and they cause the concrete to break down faster. We fix sinking driveways all across Sacramento, including Arden-Arcade, Natomas, Citrus Heights, and East Sacramento.
Before we inject anything, we measure how much each panel has dropped. We use a digital inclinometer to read the exact tilt of the slab at every drill point. This gives us a precise number so we know exactly how much lift is needed in each spot. Next, we inject a two-component polyurethane geopolymer foam with a density of 40 pounds per cubic foot beneath the slab. This foam expands and fills the void. It lifts the concrete back to the correct grade and cures in under 30 minutes. Also, it does not wash out of the base over time the way mudjacking slurry can.
If your driveway meets the public curb or sidewalk, the repair must follow City of Sacramento Standard Construction Specifications Section 40-3.01., This section sets the rules for how driveway flatwork repairs must be done near a public right of way. We follow those rules on every driveway leveling job.
Sidewalk and Curb Leveling
A raised or sunken sidewalk panel is both a safety risk and a legal problem. A gap of just half an inch between two panels is enough to qualify as a trip hazard. Homeowners, HOAs, and municipalities can face citations and liability claims when sidewalk damage goes unfixed. We repair sidewalk panels across Midtown Sacramento, Land Park, Carmichael, Arden-Arcade, and Downtown.
We check the condition of the concrete before we drill. We use a Proceq Pundit Lab+ ultrasonic pulse velocity meter to send a sound wave through each panel. When the wave travels slowly, it tells us there is a void or a weak area below the surface. This step lets us place every drill hole exactly where it needs to go. Next, we inject a hydrophobic closed-cell polyurethane foam rated at 2.0 pounds per cubic foot and tested to ASTM D1622 standards. This foam resists water and holds its shape through Sacramento's wet winters and dry summers. So the lift stays consistent over time.,
Public sidewalk repairs must meet ADA Standards for Accessible Design Section 302.1, which sets the surface tolerance for ground surfaces on accessible routes. Also, under California Government Code Section 5610, property owners are legally responsible for keeping the sidewalk next to their property safe. We repair your panels to meet both of those requirements.
Foundation Slab Leveling
When the slab a home or building sits on settles unevenly, the whole structure is affected. Doors begin to stick because their frames shift. Cracks appear in drywall along diagonal lines from window or door corners. Gaps open between the floor and the base of interior walls. These signs point to the foundation slab beneath the structure, not to the walls or doors themselves. We handle foundation slab leveling in East Sacramento, Land Park, South Sacramento, Rancho Cordova, and Carmichael.
Before we inject, we place an Avongard Plot crack gauge across any existing cracks in the slab. This gauge reads movement in 0.1-millimeter steps and records what happens during and after injection. It also gives us a starting measurement to compare against over time. We inject Uretek 486 Star structural polyurethane foam beneath the foundation. This foam has a compressive strength of 250 psi, rated to ASTM D1621. It is one of the few geotechnical foams built specifically to carry structural load.
Foundation slab repairs must meet California Residential Code Section R506.1, which covers minimum slab thickness and support conditions for slabs on ground. Also, structural slab work in Sacramento County requires a building permit under Sacramento County Code Chapter 16.04.010 before any work begins. We manage that permit process for you from start to finish.
Interior Concrete Floor Leveling
You can often feel an uneven interior floor before you see it clearly. Floating floors buckle when the concrete beneath them is not flat. Tile cracks at the grout lines where the slab dips. In commercial spaces, a floor that fails a flatness test can delay a business opening or a tenant move-in. We level interior concrete floors in Midtown Sacramento lofts, Downtown offices, North Highlands warehouses, and South Sacramento commercial zones.
We apply Mapei Ultraplan 1 Plus as the surface correction layer. This is a calcium aluminate compound with a compressive strength of 25 megapascals. It can be poured from one sixteenth of an inch up to 1.5 inches deep in a single application. This range makes it useful for correcting both slight surface tilts and deeper low spots in the same pour. For large commercial floor areas, we use a laser screed with sonic grade control to hold the surface within 3 millimeters across the full pour.
Floor flatness on commercial projects is measured to ASTM E1155, the standard test method for determining FF floor flatness and FL floor levelness. Most commercial occupancies require a minimum FF25 flatness rating and a minimum FL20 levelness rating. Our finished interior floors meet or go beyond both of those numbers.

Garage Floor Leveling
Two things cause garage floors to sink over time. First, the weight of vehicles pressing on the same spots compresses the soil below the slab. Second, Sacramento's clay soil dries out in summer and pulls away from the underside of the concrete. The result is a floor that rocks, tilts toward the door, or collects puddles of oil and water. We fix garage floors in Citrus Heights, Antelope, Carmichael, Rancho Cordova, and across Sacramento.
For surface-level correction, we apply Ardex K-15 calcium aluminate self-leveling underlayment. This product reaches 3,500 psi compressive strength at 28 days. It can be applied from a paper-thin feather edge up to 1.5 inches thick in a single pour. When soil voids are the root cause of the problem, we inject polyurethane foam beneath the slab first to stabilize the base. Then we apply the surface compound on top of the stabilized concrete. We verify the finished floor using a rotating laser level with a floor-mounted tripod and digital receiver. This confirms the floor sits within one eighth of an inch over a 10-foot span.
California Building Code Section 1907.1 sets the concrete floor finish standards for residential occupancies. Our finished garage floors meet those requirements.
Concrete Void Filling
A slab can look perfectly fine on the surface while having no support underneath it. Voids form when soil washes away from beneath a slab, when clay dries and pulls back, or when old tree roots break down and leave gaps in the ground. A slab sitting over a void is under stress every time someone walks or drives on it. It will eventually crack or drop suddenly. We locate and fill voids beneath slabs across Sacramento, including South Sacramento, Old Sacramento, and Pocket-Greenhaven.
We map the ground beneath the slab before we drill a single hole. We use a GSSI SIR-4000 ground-penetrating radar unit with a 400 MHz antenna to read sub-slab conditions down to four feet deep. This shows us the size and location of each void so we drill only where the material needs to go. We fill confirmed voids with RR401 geotechnical foam, a two-part expanding product with a post-cure density of 6.0 pounds per cubic foot and a compressive strength of 75 psi tested to ASTM D1621. This is one of the densest foam products available for residential and commercial void work. It does not shrink, absorb water, or lose volume after it sets.
Work near a public right of way may require documentation under the City of Sacramento Engineering Design and Procedures Manual, Chapter 6. We provide that documentation on every void-filling project that involves city-adjacent property.
Crack and Joint Repair After Leveling
Lifting the slab is step one. Sealing the cracks and joints is step two, and most people skip it. An open crack lets rainwater reach the soil beneath the concrete. That water softens the ground and starts the settling cycle all over again. Sealing the cracks protects the lift and adds years to the life of the repair. We perform crack and joint sealing on driveways, sidewalks, patios, and commercial slabs across Sacramento.
We use Sika Injection-451 for crack repair. This is a low-viscosity two-component epoxy resin that meets ASTM C881 Type I Grade 1 standards and cures with a tensile strength of 7,500 psi. We inject it using a ,dual-cartridge gun set to a 2-to-1 A-to-B mix ratio. That ratio is required for the product to meet its ASTM specification. The resin bonds to both walls of the crack and restores the slab's strength across the break. For control joints and expansion joints, we use a backer rod with a flexible polyurethane sealant that allows the joint to move with the concrete instead of cracking under it.
Crack repair on public concrete surfaces is evaluated against ACI 224.1R-07, the standard guide for evaluating and repairing cracks in concrete structures. Sacramento County Public Works accepts crack repairs using Sacramento County Improvement Standards Chapter 6, Section 6.4,as the baseline criteria for public infrastructure slab work. Our repairs satisfy both standards.
Pool Deck Concrete Leveling
People walk on pool decks barefoot and wet. A raised panel edge near water is a serious hazard. Also, when a slab sinks close to the pool edge, it can open a gap at the pool coping. That gap lets water wash behind the deck and speed up the settling. We level pool decks in Elk Grove, Natomas, Arden-Arcade, Pocket-Greenhaven, and Citrus Heights.
We use Alchemy-Spetec AP Lift 475 polyurethane foam for every pool deck project. This foam cures at a density of 4.75 pounds per cubic foot. It is also certified to NSF/ANSI 61 standards, which means it is cleared for use near potable water systems. This matters when plumbing lines run under the deck. During injection, we monitor the gap at the pool coping using a feeler gauge set with a reading range of 0.001 to 0.025 inches. This lets us stop the lift at exactly the right point so the panel is flush and the gap is fully closed.
California Building Code Section 3106B.4 sets the requirements for pool barrier and deck surface conditions. We confirm our work meets that standard on every pool deck we finish.
How the Process Works
Free On-Site Assessment
We come to your property, look at the slab, check the slope, and identify any signs of voids beneath the surface. We also let you know upfront if a permit is required before we start.
Drill Layout
We mark a pattern of small holes across the slab. Each hole is roughly the size of a dime. The pattern is based on where the void is located and how much lift is needed at each point.
Injection
We pump foam or grout beneath the slab. For foam jobs, we watch the lift happen in real time and stop the injection when each panel reaches the correct grade.
Crack and Joint Sealing
After the lift is complete, we inspect every crack and open joint. We seal them to prevent water from reaching the base and restarting the settlement cycle.
Patch and Clean Up
We fill every drill hole with a matching concrete patch compound. We clean the work area completely. The surface is ready to use within an hour for foam injection jobs.
Final Verification
We take a final level reading across the repaired surface. We walk through the results with you and confirm the job meets the correct grade before we leave.
