Garage Floor Leveling in Milwaukee, WI

An uneven garage floor isn’t just an eyesore; it’s a safety hazard and a sign of a deeper problem. Over time, soil erosion, water damage, and natural settling can cause concrete slabs to sink, crack, and create tripping hazards. These issues can lower your home’s value, cause drainage problems, and even damage your vehicles.

At Accurate Basement Repair, we provide professional garage floor leveling services that lift and stabilize sunken slabs without the mess, cost, or downtime of a full replacement. We use a high-density polyurethane foam that is injected beneath the concrete to fill voids, stabilize the soil, and gently lift the slab back to a level position. The process is fast, clean, and provides a lasting fix, restoring both the safety and appearance of your home.

Garage floors sink for many reasons, but the most common cause is the instability of the soil beneath the concrete.

Here’s what can lead to a sinking garage floor:

• Soil Erosion: Rain and melting snow can wash away the soil beneath your garage, creating empty voids where the slab has no support.
• Poor Drainage: If water isn’t directed away from your garage, it can pool and seep into the ground, causing the soil to become saturated and lose its density.
• Heavy Loads: The weight of vehicles, especially heavy trucks or RVs, can put too much pressure on the soil, causing it to compact and settle.
• Natural Ground Settling: All soil settles over time, but some types of soil are more prone to shifting, which can lead to uneven concrete slabs.

Garage floors take a beating, from heavy vehicles to daily foot traffic to shifting soil below. When the concrete starts to sink or slope, the risks go beyond appearance:

• It can damage your car.
  A sunken garage floor can throw off your vehicle’s alignment, increase tire wear, and lead to suspension issues over time.
• It creates trip hazards.
  Uneven slabs with sharp edges or height differences can cause dangerous stumbles for you, your kids, or anyone visiting your home.
• Water pools where it shouldn’t.
  Low spots collect standing water, which seeps into concrete, breaks down the surface, and increases humidity that can impact your home’s foundation.
• Your garage loses its purpose.
  Sloped, cracked floors make it harder to park safely, store tools, or use your garage as a workspace. The room becomes a liability instead of an asset.
• It hurts your curb appeal and resale value.
  Buyers notice broken or sunken floors. A level garage makes your entire home look more stable, finished, and move-in ready.

• Cracks are spreading across the surface
  If your garage floor is marked by long, widening cracks, that’s often a sign the slab is settling unevenly. These cracks may seem minor at first, but over time, they can worsen, signaling deeper structural movement beneath the concrete.
  
• Low spots where water pools
  Water that collects in certain areas of your garage is more than a nuisance; it’s a warning. Standing water accelerates slab deterioration, leads to mold growth, and can eventually compromise the foundation if left unchecked.
• Dips, slopes, or sunken areas
  A garage floor that’s no longer flat makes daily life harder and more dangerous. Uneven surfaces create tripping hazards, make parking difficult, and can even damage tires or suspension over time.
• Gaps between the floor and the base of the walls
  When your garage floor begins to pull away from the walls, it’s a clear sign of soil settlement or voids beneath the slab. These gaps can widen quickly, allowing moisture, pests, and even contributing to further sinking.
• Tripping hazards or sharp “lip” edges where slabs have dropped
  If you’ve stumbled or noticed a sudden height change between parts of your garage floor, that’s a strong sign of settlement. It creates serious safety risks and makes everyday movement more difficult.

1. Visual & Structural Assessment
   Our Certified Foundation Specialist evaluates your garage floor, driveway connection, and the soil underneath.
