Void Filling & Supporting

Strengthen the ground beneath your concrete to prevent sinking, cracking, and long term damage.

A Practical Solution For Weak Soil Support

Void filling and slab stabilization focuses on fixing the hidden problem beneath your concrete. When soil shifts or washes away, empty spaces form under the slab. Even if the surface still looks fine, the support underneath is compromised.

At Solid Lifters, we use expanding polyurethane foam to fill these gaps and rebuild a solid base. This restores support, prevents future movement, and protects your concrete from sinking or breaking.

Instead of waiting for visible damage, this service addresses the issue at its source and helps maintain long term stability.

Why homeowners choose slab stabilization:

Why Support Beneath Concrete Fails

Concrete depends entirely on the ground beneath it. When that support weakens, problems begin to develop below the surface.

In Eastern Idaho, common causes include:

How We Stabilize The Slab

Our process focuses on restoring strong, reliable support beneath your concrete.

1. Inspection

We assess the condition of the slab and identify areas where support is missing.

2. Drilling

Small access points are created to reach beneath the concrete.

3. Foam Injection

Polyurethane foam is injected below the slab where it expands to fill voids and reinforce the soil.

4. Stabilization and Seal

The material hardens into a durable base. The surface is sealed and ready for use quickly.

What Happens When Support Is Lost

When the base beneath concrete is no longer stable, the slab above becomes vulnerable to movement and damage.

This often leads to:

Why Polyurethane Is The Better Option

Stabilizing concrete requires a material that can fully adapt to the space beneath the slab while providing long term strength.

Polyurethane foam delivers this by:

  • Expanding to fill all gaps and voids
  • Remaining lightweight to protect soil integrity
  • Resisting water and erosion
  • Curing quickly for fast turnaround
  • Providing durable and lasting support

 

This makes it an ideal solution for reinforcing concrete from below.

Where Slab Stabilization Works Best

This service is effective anywhere concrete may have weakened support beneath it, even if sinking has not started yet.

Common areas include:

  • Driveways
  • Sidewalks and walkways
  • Garage floors
  • Patios
  • Foundation-adjacent concrete
  • Steps and entry areas

Frequently Asked Questions

In many cases, the signs are not immediately visible. You may notice hollow sounds when tapping the surface, small cracks forming, or slight movement when weight is applied. Over time, this can lead to sinking or uneven areas. A professional inspection can confirm if voids or weak soil are present beneath the slab.

Yes, and it is often the best time to do it. Filling voids early helps prevent the slab from dropping or cracking later. Addressing the issue before visible damage appears can save you from more expensive repairs in the future.

Void filling is often part of the lifting process, but it can also be done as a standalone service. If your concrete is still level but has gaps underneath, stabilizing the base early can prevent the need for lifting later.

Polyurethane foam is designed to provide long term support. It is resistant to moisture and does not break down easily over time. When properly applied, it can maintain stability for many years.

Void filling and slab stabilization significantly reduce the risk of future sinking and cracking. While no solution can stop all ground movement, reinforcing the base beneath your concrete greatly improves its durability and performance.
