How Void Filling Works

Void filling is the process of identifying and filling empty spaces beneath the ground surface using specialized materials. These voids can form due to:

Water washout from plumbing leaks
Soil settling or erosion from poor drainage
Buried debris decomposition (wood, stumps, trash)
Rodent or insect activity undermining soil
Improperly compacted backfill during construction
Sinkholes in areas with soluble rock

Void filling solutions involve injecting a flowable material—such as a cement-based slurry, polyurethane foam, or structural grout—into the cavity through small surface ports. Once filled, the material hardens and restores contact between the ground and the structure, eliminating air pockets and risk of future collapse.

Benefits of Professional Void Filling

Unlike cosmetic patching or short-term slab lifting, void filling addresses the underlying cause of structural instability. It’s one of the best preventative and corrective methods available for homeowners and property managers.

Benefits include:

Restores underground support to slabs and foundations
Prevents further sinking, cracking, or collapse
Seals pathways where water can erode soil
Non-invasive with minimal drilling or surface impact
Increases property safety and long-term value
Compatible with other repairs like piering or drainage
Reduces need for costly structural reconstruction later

Void filling is a smart investment in structural security and peace of mind.

What to Expect During Void Filling in Carthage

Our process is clean, efficient, and designed to minimize disruption to your home and landscaping. We identify, access, and fill voids with surgical precision.

Step-by-step process:

Inspection and Void Identification
- We use soil probes, GPR (ground-penetrating radar), or pressure tests to locate voids.
- A detailed site plan is created showing affected zones and injection layout.
Repair Plan and Estimate
- Based on void depth, size, and location, we recommend the right fill material and method.
- A quote is provided, including time, materials, and optional warranty.
Drilling and Port Installation
- We drill small holes (typically 1–2 inches in diameter) at targeted points for material injection.
Injection Process
- Foam or slurry is pumped in carefully under controlled pressure.
- As material fills the void, we monitor changes in elevation and resistance to ensure proper fill.
Patching and Cleanup
- Injection ports are sealed, and any disturbed concrete or soil is restored.
- We leave your property clean, stable, and safer than when we arrived.

Most residential void fills are completed in one day, depending on the void size and injection method.

FAQs About Void Filling

Find answers to our most commonly asked questions, from our services and pricing to the benefits of working with us. For more assistance, feel free to reach out to our team!

Q: How do I know if there’s a void under my slab?

A: If your slab feels hollow, shows uneven settling, or has frequent cracks, there may be a void underneath. We use probes and radar to confirm.

Q: Can foam be used to fill deep voids?

A: Polyurethane foam is best for small to moderate voids. For large or deep voids, we use cement-based grout or slurry.

Q: Will this lift my concrete slab?

A: In some cases, yes. Foam and grout can gently raise slabs as they fill the space. However, if significant lifting is needed, slab jacking may be recommended.

Q: Is this a permanent fix?

A: Yes. Once hardened, the fill material does not shrink or degrade and restores full support beneath your structure.
