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.

Call us at (615) 880-6449 for a free garage floor inspection.

$400–$2,000+ depending on the size of the settled area, number of voids, and extent of crack sealing. Typical cost range for this service, depending on scope and site conditions.
When this isn't the fix: If the garage floor slab is severely cracked, heaved, or the subgrade has failed extensively, section replacement may be more practical than lifting. We evaluate slab condition during the inspection and give you a clear recommendation.

[ 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.

[ 04 ]  FAQ

Garage Floor Repair questions

Garage floor settlement at the apron, the concrete just inside or outside the garage door, is one of the most common issues we see in Middle Tennessee. The apron settles faster than the interior slab because vehicle wheel loads are concentrated there and drainage from the driveway can erode soil from beneath it. Polyurethane foam fills the void and lifts the slab back to close the gap.

In most cases, lifting a settled garage floor back to level actually improves door operation by restoring the correct clearance and seal at the bottom. If a door has been adjusted to compensate for a settled floor, re-adjustment after lifting may be needed.

We can lift and crack-seal a garage floor before epoxy coating is applied. If an existing epoxy coating is cracked, the repair involves opening the crack through the coating, sealing it, and then patching the coating surface. We recommend discussing this scenario during the inspection.

Most garage floor lifting and crack sealing jobs are completed in two to three hours. Vehicles can typically return to the garage the same day the work is completed.

Polyurethane foam fills the void permanently. If the water source that caused the original erosion, such as a poorly directed downspout, plumbing leak, or inadequate drainage at the apron, is not addressed, new erosion could develop over time. We flag drainage issues during the inspection and recommend corrections alongside the lifting work.
