Concrete Lifting Services in Marengo

When a slab sinks, it’s rarely a flaw in the concrete itself. More often it comes down to the soil underneath losing volume, whether from erosion, poor original compaction, or seasonal shifts in moisture. Because Marengo is a historic small McHenry County town with an older housing stock, properties here can be affected by more than one of these causes at once, which is why we look closely at each slab and the ground around it before recommending a fix.

To correct the settling, we drill small access holes into the existing concrete and inject polyurethane foam beneath it. The foam fills the gaps left by eroded or settled soil and lifts the slab as it expands, restoring it to level without removing or replacing anything. Because the foam is lightweight and sets quickly, there’s minimal disturbance to the surrounding landscaping. Because this method doesn’t require excavation or new concrete, it’s typically faster than a full replacement and leaves your yard largely undisturbed. It works well on driveways, walkways, patios, garage floors, and other exterior flatwork.
