Driveways, walkways, patios, pool decks, and garage floors fail at the surface long before they fail underneath. We repair the concrete you already own, and we tell you which of the two problems you actually have.
A local specialist will evaluate your foundation, walk you through the findings, and send a clear estimate. No cost, no pressure.
Concrete fails in two different ways and they need two different answers. A slab that has cracked, spalled, pitted, or flaked has a surface and material problem: water found a way in, a joint stopped absorbing movement, road salt or pool chemistry attacked the top layer, or the slab shrank as it cured and opened a line. A slab that has dropped out of level has a soil problem, which is a concrete leveling question rather than a concrete repair one. This silo is the first kind, and the free evaluation sorts your concrete into one bin or the other before anyone quotes anything.
Most concrete repair work starts with water, because water is what turns a cosmetic line into a structural one. A hairline crack that stays dry can sit there for years. The same crack fed by a downspout or a sprinkler carries water to the soil below, and the freeze, the swell, and the washout that follow widen it every season. That is why routing and sealing a crack properly is worth more than it looks, why a sealed joint is the cheapest repair on this site, and why we look at drainage on every visit rather than only at the concrete.
We repair driveways, walkways, patios, pool decks, garage floors, steps, and commercial flatwork across California, Arizona, and Nevada. Surface damage comes with its own vocabulary, and the concrete repair warning signs page walks through the patterns we see most: cracks that widen, expansion joints that have given up, pitting and flaking where the top layer scaled away, and the gaps that open where a slab meets a wall. Each of them points at one of the concrete repair methods we actually use, and none of them points at demolition by default.
Dalinghaus Foundation Repair has completed more than 2,000 projects across the three states since brothers Brian and Brad Dalinghaus founded the company in 2011. Every concrete project starts with a free evaluation: we measure how far the slab has moved, read what the damage pattern is telling us, and put the findings and the options in writing whether or not you hire us, including the option to seal it and watch it for a season.
Pick the symptom that best fits. We'll tell you what it likely means and where to go next.
Most concrete repair problems start as small symptoms. Catching them early is the difference between a small, planned fix and a major reconstruction. These are the warning signs we see most often.
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 sinks because the soil beneath it stopped holding it up. In California, Arizona, and Nevada the usual causes are clay soil that swells when wet and shrinks when dry, water washing soil out from under the slab, fill dirt that was never compacted properly, and tree roots that lift a slab and then leave a gap when they die back. The slab drops into whatever space the soil leaves behind.
