Allen's clay soil doesn't stop at the driveway. It works under the garage floor too, and that slab often separates from the foundation footing as moisture cycles through the ground each season.
Allen Concrete Lifting lifts the sunken garage slab and seals the gap at the foundation joint, so water stops finding its way in and the floor sits level again.

FAQs
Garage Floor Leveling FAQs
What causes garage floor slabs to separate from the foundation?
The garage slab and the home's foundation footing are usually poured separately. As the clay soil under the garage slab shrinks and swells, the slab moves independently from the foundation, opening a gap.
How do I know if it's foundation settling or just the slab settling?
Foundation settling usually shows up as cracks in walls or doors that stick throughout the house. Slab-only settling stays contained to the garage floor and the joint where it meets the foundation.
Will caulking the gap fix the problem?
Caulk seals the surface but doesn't stop the slab from moving further. Lifting the slab first gives the seal something stable to hold.
Does garage floor leveling need a permit?
Repair-only leveling on an existing slab typically doesn't. If the work ties into structural foundation repair, that's a different scope and may require one.
How long does a garage floor lift take?
Most jobs finish in a single visit, with foam curing in about 15 minutes before the floor is walkable.
