HOME › GARAGE FLOOR LEVELING
A settling garage floor rarely announces itself — until the slab cracks, the door won't seal, or a step forms at the driveway approach. Jack It Up lifts sunken garage slabs back to grade with polyurethane foam injection, closing gaps at the perimeter and stopping settlement before it stresses the foundation line.
A widening crack across the slab, a gap opening under the garage door seal, a lip forming where garage meets driveway, or a hollow sound underfoot — all point to voids under the concrete. Left alone, the slab keeps dropping and cracks keep spreading.
Our equipment is hose-fed, so we work inside the garage without heavy machinery. We drill dime-sized holes, inject expanding foam beneath the slab, and raise it evenly back to level — including realigning that step at the driveway approach.
Garage slabs often settle right along the perimeter beam. Re-supporting the slab with foam relieves that edge, restores door alignment and drainage, and keeps water from funneling under your foundation.
Only the area over the settled sections — usually one side or the approach. We'll tell you exactly what to move at the free estimate.
Yes — that offset is one of the most common lifts we do. We raise the low slab flush so cars stop scraping and water stops pooling at the seam.
Cracks don't vanish, but lifting closes them tight and stops them from spreading. We can also seal them against moisture as part of the job.
