Restore A Level, Safe Garage Floor Without Replacing The Slab
[ 01 ] The Honest Answer
What you should know about garage floor repair
Garage Floor Repair For Middle Tennessee Homeowners
Garage floors take a daily beating from vehicle loads, temperature swings, oil and water infiltration, and the same clay soil movement that affects every concrete surface in Middle Tennessee. When a garage floor slab settles, it creates problems beyond aesthetics, gaps at the garage door apron allow water intrusion and pests, uneven surfaces damage vehicle tires and create trip hazards, and settled areas at the interior transitions become safety concerns.
Ground Up Foundation Repair lifts settled garage floor slabs with polyurethane foam and seals cracks with NexusPro flexible sealant. The repair is completed in a few hours and the floor is ready for vehicle traffic the same day.
Garage Floor Problems We Repair
- Settled slab at the garage door apron: A gap between the apron and the driveway or a drop at the threshold allows water, pests, and cold air into the garage
- Interior slab settlement: Low spots beneath vehicle parking areas caused by soil voids or erosion
- Cracks in the floor surface: Hairline to significant cracks sealed with NexusPro to prevent moisture intrusion and further expansion
- Door alignment problems: Garage doors that don't seal at the bottom or jam in their tracks due to floor movement
- Drainage reversal: Slab tilt that sends water toward the interior of the garage rather than toward the door
Why Garage Floors Settle in Nashville
Garage slabs are often poured with less subgrade preparation than foundation slabs, and many homes in Rutherford and Davidson counties were built on fill soil that was not fully compacted. Over time, vehicle loads compress the soil further and water from car wash runoff, rain tracking, or plumbing leaks erodes fines from beneath the slab. Polyurethane foam fills those voids permanently without adding weight that could cause new compression.

[ 02 ] How It Works
What to expect, start to finish
Garage Floor Assessment
We evaluate the entire floor surface, identify settled sections, check for voids beneath the slab with sounding, and assess the apron and door transition conditions.
Drill Injection Ports
Small ports are drilled at strategic locations through the garage floor slab. Holes are positioned for maximum foam coverage of identified void areas.
Inject Polyurethane Foam And Lift
Polyurethane foam is injected through each port, expanding to fill voids and lifting settled sections back to grade. Lift is monitored continuously.
Crack Sealing And Cleanup
All cracks are sealed with NexusPro. Injection ports are patched and the floor is swept clean. Vehicles can return to the garage the same day.
Garage floors are one of the most overlooked settlement problems we see. By the time a homeowner calls us, the gap at the apron is big enough to let mice in and the garage door doesn't seal at the bottom. Polyurethane foam closes that gap the same day.
