Dalinghaus offers concrete lifting and raising for sunken driveways, sidewalks, patios, pool decks, and garage floors in Southern California, Arizona, and Nevada. Polyurethane foam lifts each settled slab back toward level without tearing out the concrete.
A local specialist will evaluate your foundation, walk you through the findings, and send a clear estimate. No cost, no pressure.
Concrete lifting and concrete raising are other names for concrete leveling: bringing a sunken slab back toward level by filling the empty space that formed under it. Dalinghaus uses it in California, Arizona, and Nevada on sunken driveways, sidewalks, patios, pool decks, garage floors and steps, injecting polyurethane foam through small holes with no demolition.
Concrete depends on the soil underneath it for support, and across Southern California, Arizona, and Nevada that soil often moves. Expansive clay swells with winter rain and shrinks in the dry months. Runoff from a roof line, a cracked irrigation line, or an Arizona monsoon storm can carry soil out from under a slab edge. Fill placed during construction can compress the first time it gets wet. Each of those can leave a void, and the slab drops into the space.
We level driveways, sidewalks, patios, pool decks, garage floors, and settled steps for homeowners and commercial property owners across all three states. The symptom you noticed is usually enough to start the conversation: a driveway panel sitting low, a walkway lip that catches a toe, a pool deck pulling away from the coping, a garage floor parting company with the slab outside it. The rest of the patterns we see are collected on the concrete leveling problem signs page.
Lifting restores a sound slab to a failed base. It cannot restore a failed slab. Concrete broken into several small pieces no longer acts as a unit, so foam underneath pushes fragments around instead of raising a surface, and we say so in the written findings rather than sell a lift that will not hold. The reverse can also be true: a thin, uniform hairline crack with no offset and no elevation change is usually curing shrinkage, which belongs with concrete repair and sealing rather than with a lift.
Dalinghaus Foundation Repair has completed more than 2,000 projects across California, Arizona, and Nevada since brothers Brian and Brad Dalinghaus founded the company in 2011. Every leveling project starts the same way: a free evaluation that measures elevations across the slab, traces the void, identifies what moved the soil, and puts the options in writing, including the option to measure again next season instead of repairing today.
Polyurethane foam raises a slab by filling the empty space under it first, then pushing the slab up from below as more foam goes in. The crew drills holes about five eighths of an inch across through the low sections and injects a two part expanding polyurethane resin beneath them.
The two liquids stay separate until they meet at the nozzle, then react and expand. The foam fills the void first and presses into the loose soil at its edges. Only after the void is full does more foam begin raising the concrete. It goes in as small shots, with elevations checked between each one, so the lift stops at grade rather than past it.
The material reaches working strength in minutes. The holes are patched, and most surfaces are back in normal use the same day.
Weight is the main reason Dalinghaus lifts with foam. Cured polyurethane weighs roughly three to four pounds per cubic foot, compared with about 150 pounds per cubic foot for the cement slurry that traditional mudjacking pumps under a slab. Foam restores support without adding much load to ground that already settled under the load it had.
Cured foam is also water resistant, which matters when water caused the void. The general term for lifting a slab with either material is slab jacking, and Dalinghaus uses polyurethane. The soil reading during the evaluation decides whether a lift is the right repair for your concrete.

Dalinghaus installed the helical pile foundation and erected the structure for a solar canopy over a staff parking lot in Southern California, working in four phases so the lot stayed open.
Show project
The back of an Irvine home had settled about 3 inches over roughly ten years. Ten helical piers went in over two days, and a 30 minute lift brought the back half of the home up 3 inches.
Show project
A hillside home in Rancho Palos Verdes split in half as the ground slid toward the slope. Dalinghaus installed helical piers about 30 feet down to competent strata or bedrock beneath it.
Show project
A beachside home in Rancho Palos Verdes settled 16 inches in a couple of months. Steel piers were driven to load bearing soil or bedrock at each excavated location, with a lift planned once they were in.
Show project
A San Clemente hillside home had settled about 2 inches and was moving toward the slope behind it. Vertical helical piers and helical tieback anchors stabilized the home and recovered part of the drop.
Show project
Two helical deck piers let a San Clemente hillside deck grow by about 12 feet, at a home Dalinghaus had lifted about 16 inches earlier.

Concrete leveling raises a sunken slab back to its original elevation by restoring the support underneath it, rather than removing and repouring the concrete. We drill small holes through the low sections, inject expanding polyurethane foam that fills the void and firms up the loose soil around it, and then lift the slab in controlled increments while watching the elevations. The holes are patched when the lift is finished.
Every step, from the free evaluation to the final elevation check.
A specialist measures elevations across the slab, traces the void underneath it, and identifies the water or soil condition that made it. You get the readings and the cause in writing, at no cost and with no obligation.
The method that fits your slab comes back in writing, with the work and the exclusions stated on the page. Nothing about the job is agreed verbally.
Outdoor flatwork goes straight to the lift. Interior work does not: a ground penetrating radar floor scan is completed before work commences, and a post tension slab requires one every time. The scan reports how thick the concrete is and the spacing and depth of what is embedded in it, so the crew drills around those findings instead of into them. It is booked at a two hour minimum and is an additional cost where the proposal does not already carry it.
Material goes in under the slab in small shots while the crew watches elevations, and the lift stops at grade rather than past it. Holes are patched, final elevations are compared against the starting survey, and the surface is typically back in service the same day.
The foam expands to fill the empty space under the concrete and lifts the slab back toward level.
