Garage Slab Leveling in the Tri-Cities

Professional Garage Slab Leveling in the Tri-Cities

Garage floors can settle over time due to shifting soil beneath the concrete slab. When this happens, the floor may become uneven, crack, or drop near the garage door or foundation.

 

A sunken garage slab can cause several problems, including water drainage issues, structural stress on the slab, and uneven surfaces that make parking or storing equipment difficult.

 

Northwest Concrete Leveling provides professional garage slab leveling using advanced polyurethane foam injection. This modern repair method lifts and stabilizes sunken concrete quickly without the need for costly replacement.

 

Most garage slab leveling projects can be completed in just a few hours, and the surface is typically ready for use the same day.

Why Do Garage Floors Sink?

Garage slabs often experience settlement due to soil movement beneath the concrete. Because garages frequently support heavy vehicles, the soil underneath can compress or shift over time.

 

Common causes include:

When the soil beneath the garage floor loses support, sections of the concrete can sink or crack.

How Garage Slab Leveling Works

Northwest Concrete Leveling uses a high-density polyurethane foam injection process to lift and stabilize uneven garage floors.

Step 1 – Inspection

We inspect the garage slab to determine the cause of settlement and identify voids beneath the concrete.

Step 2 – Small Injection Points

Small holes are drilled into the slab where the foam will be injected.

Step 3 – Foam Injection

Structural polyurethane foam is injected beneath the slab where it expands to fill voids and lift the concrete.

Step 4 – Precision Leveling

The garage floor is carefully raised back to its proper position and stabilized.
