Sunken concrete, lifted in an afternoon.

Why slabs sink here

Utah slabs settle for three main reasons: poorly compacted backfill under a slab poured too soon after construction, soil washing out from under an edge because water was directed there, and expansive clay cycling wet and dry beneath it. Driveways and garage aprons over utility trench backfill are the classic case, because that trench was never compacted to the same standard as the surrounding ground.

Foam versus slurry

Polyurethane foam is injected through small ports, expands to lift the slab, weighs a fraction of what mudjacking slurry does, and cures in minutes so you can drive on it the same day. It does not add load to already weak soil. Traditional mudjacking uses a cement slurry through larger holes; it costs less and remains reasonable on stable soil with a heavy slab. On soft or expansive ground, adding the weight of slurry is working against yourself.

Where it matters more than looks

A settled slab against a house is not just a trip hazard. Once a driveway or patio pitches back toward the foundation it becomes a delivery system aimed at your basement, and it will keep feeding the wall until the slope is corrected. A lot of the wet-basement calls we take start as a concrete problem.

What cannot be lifted

Slabs that are severely cracked into many pieces, badly spalled, or crumbling are replacement candidates — lifting fragments just makes a jigsaw. We will tell you when you are past the point where lifting is honest.
