Garage floor leveling is essential for maintaining a safe and functional garage space. Over time, floors can become uneven due to various factors, leading to potential hazards. This guide offers comprehensive steps to level your garage floor for a smooth and durable surface.

Identifying the Problem

First, identify low and high spots on your garage floor using a straightedge or level. Mark these areas to determine the extent of unevenness and choose the appropriate leveling method.

Leveling Techniques

Self-leveling Concrete Garage Floor:

For minor unevenness, this might be the most accessible and affordable way. Mix the self-leveling concrete according to the manufacturer’s instructions and pour over low areas, and voila, you’re done self leveling garage floor. 

Grinding High Spots:

Use an angle grinder for high spots, especially where the slab has cracked. This method is effective for significant unevenness.

Polyurethane Our Concrete Lifting Technique:

A less invasive and cost-effective method. Small holes are drilled, and a two-part epoxy mix is injected, expanding into foam that lifts the concrete.

Use of Polyurethane for Leveling Garage Floor:

We emphasize the use of polyurethane for concrete leveling. This method is less invasive and more cost-effective compared to concrete replacement. It involves drilling small holes and injecting a two-part epoxy mix that expands into foam, lifting the concrete. This foam is hydrophobic, preventing water infiltration, and it doesn’t fracture or fail, ensuring long-term stability.

Process Overview

  • Drilling Holes: Small holes are drilled in the concrete.
  • Injecting Epoxy Mix: A two-part epoxy is injected, which reacts and expands into foam.
  • Lifting and Leveling: The foam lifts the recessed areas, stabilizing the soil underneath.
  • Filling Holes: Injection holes are filled with cementitious grout for a seamless look.

Benefits of Polyurethane Leveling

  • Environmentally friendly and safe.
  • Strong, lightweight, and dense.
  • Resistant to moisture and soil chemicals.
  • Reduces the likelihood of new gaps or settlement.
  • Quick curing time (about 15 minutes).

Why Choose Polyurethane Leveling?

Polyurethane leveling is recommended for its affordability, speed, and effectiveness in preventing future sinking. It’s a durable solution, especially in environments where soil conditions fluctuate.

Signs of Garage Floor Issues

  • Misaligned garage frame or roof.
  • Cracks or bowing in interior or exterior walls.
  • Stair-step cracks in exterior brickwork.
  • Exterior walls separate from the main house.
  • Problems with garage windows and doors.

Cost Effectiveness

The cost of polyurethane leveling compared to concrete replacement is significantly lower. It’s a quick process, usually completed in less than a day, saving both time and money.

Environmental Safety

The polyurethane used is non-toxic and safe for the environment, even in potable water. It forms an impermeable, solid structure, ensuring durability and safety.

Noise Level

The process is not excessively loud, making it less disruptive.

Customized Approach

Each project is assessed individually, with the amount of polyurethane injected tailored to the specific needs of the garage floor.



What causes garage floors to become uneven?

Uneven garage floors can result from soil settlement, poor initial installation, water damage, or natural shifting of the ground.

Is it possible to level a garage floor by myself?

Yes, for minor leveling tasks, using self-leveling concrete is manageable. However, for more significant issues, professional assistance is recommended.

How long does it take for leveling compounds to dry?

Self-leveling compounds typically dry within a few hours, but it’s best to wait 24 hours before heavy use. Polyurethane foam cures even faster, often within 15 minutes.

Are there environmentally friendly options for garage floor leveling?

Yes, certain polyurethane foam products are environmentally friendly and safe, even for use in potable water.

Can all types of unevenness be fixed with leveling?

Most types of unevenness can be addressed with leveling techniques, but extremely damaged floors might require more extensive repair or replacement.

What is the best method for leveling a severely uneven garage floor?

Polyurethane our concrete lifting technique or professional mud jacking might be the most effective solution for severe unevenness.


Polyurethane concrete leveling is a modern, effective solution for garage floor leveling. It offers numerous benefits, including environmental friendliness, cost-effectiveness, and durability. Recognizing early signs of floor sinking and opting for this method can save significant time and money in the long run.
