Sinking concrete? Here is what you should know:

Concrete leveling (also called mudjacking or slabjacking) is a cost-effective repair process that raises sunken or uneven concrete slabs by filling the void beneath them rather than tearing out and replacing the concrete entirely. Our process: we core-drill a series of 1-inch holes in the affected slab, then pressure-inject a high-density limestone grout through those holes at 150 to 750 psi. As the grout fills the void, it lifts the slab back to its original height. The holes are capped, and the surface is ready for immediate use. No curing time, no waiting.

Yes, significantly. Concrete replacement requires demolition, hauling debris, forming, pouring, and a multi-day cure period before the surface can be used. Leveling typically costs a fraction of that, with same-day results and no mess left behind. As long as the existing slab is structurally sound, leveling is almost always the smarter choice for homeowners and business owners throughout Erie, Niagara, and Monroe County.

We level driveways, sidewalks, garage floors, patio slabs, pool decks, basement floors, warehouse and factory floors, and loading docks. If it is a concrete slab sitting on a settled base, we can likely lift it.

This is completely normal and expected. When concrete steps are originally poured, a wooden form surrounds the area. Once removed, a natural gap remains at the back of the step. After leveling, the slab rises vertically, not horizontally, so that original gap becomes visible again. It is not a defect and is not designed to be filled or patched. If you have any concerns, just ask us during the job.

In Western New York, the number one culprit is the freeze-thaw cycle. Buffalo, Niagara Falls, and Rochester all average over 90 freeze-thaw events per year. Water seeps under your slab, freezes and expands, then thaws and drains away, leaving a void. Over time the slab loses its support and sinks. Other common causes include poor soil compaction when the concrete was originally poured, clay-heavy soils throughout Erie, Niagara, and Monroe County that shrink and swell seasonally, improper drainage that channels water beneath slabs, and tree roots that push and erode surrounding soil.

As water erodes the soil beneath a slab or organic material decomposes, a void forms. Without support, the slab shifts under its own weight and under traffic loads. Our limestone grout fills that void completely, restoring a stable, solid base.

Few places in the country stress concrete as hard as this region. Erie, Niagara, and Monroe County all get heavy lake-effect snowfall requiring frequent plowing and salting, dramatic temperature swings from well below freezing in January to humid summer heat, and clay-dominant soils that hold moisture and shift substantially between seasons. Properties near the Niagara River, Lake Ontario shoreline, and the Genesee River corridor can face additional moisture exposure that accelerates settling. Regular inspection and prompt repair are the best defense.

Polyurethane foam is a petroleum-based chemical product. Limestone grout is a natural material that replaces lost earth with more solid earth, which is exactly what belongs beneath a concrete slab. Our high-density limestone slurry reaches compressive strengths of 250 to 6,500 psi depending on mix, flows naturally into irregular voids, and has proven durability going back centuries. It is also non-toxic, does not off-gas, and does not degrade over time the way some foam products can.

Yes. Leveling eliminates the need to produce new concrete (a carbon-intensive process), haul away demolished slabs, or introduce synthetic chemicals into the ground. We restore what is there using natural materials. For customers throughout the Buffalo, Niagara Falls, and Rochester areas who care about their environmental footprint, that distinction matters.

With two conditions met, the repair lasts many years: the joints and cracks in the slab are caulked to prevent future water intrusion, and any drainage issues that caused the original void are corrected. Without addressing drainage, water will eventually erode new voids. We are happy to point out drainage concerns during your estimate visit.

Leveling works best when the slab is structurally intact but displaced. If the concrete is severely crumbled, broken into many small pieces, or has deep structural cracks running all the way through, replacement may be the better path. The easiest way to find out is to send us a photo using our contact form. We will give you an honest assessment and a fast estimate.

Use our Contact page, describe the area that needs leveling, and attach a photo or two. Photos allow us to give you a fast, accurate estimate without requiring an immediate site visit. We serve all of Erie, Niagara, and Monroe County including Buffalo, Cheektowaga, Tonawanda, Amherst, Williamsville, Orchard Park, Hamburg, Lackawanna, Niagara Falls, Lockport, North Tonawanda, Wheatfield, Lewiston, Rochester, Irondequoit, Greece, Henrietta, Pittsford, Webster, Gates, Penfield, and surrounding communities.

We work through most of the calendar year, but spring through fall is the ideal window. After the freeze-thaw season ends in late March or April, voids are fully formed and easy to assess. We book up quickly once the weather breaks across Erie, Niagara, and Monroe County, so contacting us as soon as you notice settling is a good idea.
