How Void Filling Works
Void filling is a process that involves injecting materials into the empty spaces beneath your foundation or concrete slabs to stabilize the structure and prevent further settling. It’s a cost-effective and minimally invasive solution for addressing these issues.
Inspection and Diagnosis
Our process begins with a detailed inspection to:
- Identify voids and gaps beneath your foundation or concrete slabs.
- Determine the root cause, such as erosion, water drainage, or poor soil compaction.
- Assess the extent of the void and any associated structural damage.
Void Filling Techniques
Depending on the size of the void and the material used, we employ several methods:
Polyurethane Foam Injection
- A lightweight, high-density foam is injected to fill voids and stabilize the structure.
- Expands quickly to provide a durable, long-lasting solution.
Cementitious Grouting
- A cement-based mixture is injected to fill larger voids and improve soil stability.
- Ideal for areas requiring added strength.
Compaction Grouting
- A dense grout mixture is injected to compact surrounding soil while filling voids.
- Prevents further soil movement and stabilizes the structure.
Soil Stabilization
- Enhances the soil’s load-bearing capacity around the void, preventing future settling.
- May involve chemical treatments or mechanical compaction.
