Void Filling in De Pere, WI
Voids beneath concrete slabs and foundations are a serious structural risk. If left unaddressed, they can lead to cracked driveways, sinking foundations, unstable floors, and major safety hazards. These voids often develop due to erosion, soil settlement, underground leaks, or poor compaction.
At De Pere Foundation Repair, we provide professional void filling services to stabilize foundations, roads, sidewalks, patios, and industrial floors. Our techniques, including polyurethane foam injection, compaction grouting, and pressure grouting, ensure long-term structural stability and safety.

How Void Filling Works
Void filling involves injecting material beneath the concrete slab or foundation to eliminate empty spaces, restore stability, and prevent future settlement. We use high-quality polyurethane foam and cementitious grouts to fill voids efficiently and permanently.
Common Causes of Voids Beneath Foundations & Concrete Slabs
- Erosion from water leaks or heavy rainfall – Excess moisture washes away supporting soil.
- Poor soil compaction during construction – Weak soil fails to provide adequate support.
- Groundwater movement & soil shrinkage – Changes in moisture cause soil to contract.
- Plumbing leaks or underground water line issues – Water seeps into the ground, eroding soil.
- Heavy traffic or structural load changes – Overloaded surfaces cause soil compression and void formation.
Signs You Need Void Filling
Voids beneath your foundation or concrete surfaces can lead to serious damage. Look for these warning signs:
- Cracked or uneven concrete slabs
- Hollow sounds beneath driveways, patios, or sidewalks
- Sinking or unstable foundation walls
- Gaps between slabs and adjacent structures
- Frequent soil shifting or erosion around your property
- Water pooling in specific areas after rain
If these signs are present, professional void filling can prevent further damage and restore structural integrity.
Our Void Filling Solutions
1. Polyurethane Foam Injection for Concrete Stabilization
We use high-density polyurethane foam injection to fill voids, stabilize concrete, and prevent further sinking.
✔ Expands to fill voids and hardens for long-term stability
✔ Lightweight and doesn’t add excessive weight to the soil
✔ Water-resistant and prevents future erosion
2. Compaction Grouting for Soil Reinforcement
Compaction grouting strengthens loose, weak, or eroded soil by injecting a thick, cementitious grout mixture.
✔ Increases soil density for added support
✔ Ideal for preventing foundation settlement
✔ Used in both residential projects
3. Pressure Grouting for Deep Void Filling
For larger voids beneath roadways, parking lots, and industrial foundations, we inject pressure grouting material to stabilize the area.
✔ Works for large-scale soil void problems
✔ Long-lasting support for heavy structures
✔ Restores stability to sinking surfaces
4. Foundation Void Filling for Structural Stability
Voids beneath foundation footings or basement floors can cause serious settlement issues. Our void-filling solutions ensure:
✔ Even weight distribution across the foundation
✔ Elimination of hollow spaces that can cause collapse
✔ Protection against water infiltration and further erosion
