Void Filling in Wilson, NC

Void Filling is a specialized technique used to fill voids or gaps in the soil beneath your foundation, which can result from soil erosion, poor compaction, or other environmental factors. By filling these voids, we restore the stability of the soil and prevent future settling or shifting. Here’s how the Void Filling process works:

1. Inspection and Assessment

• The first step in Void Filling is a thorough inspection of your foundation and the surrounding soil. Our experts assess:
  • The size and location of the voids beneath your foundation.
  • The extent of soil erosion or instability around the foundation.
  • Any signs of structural damage such as cracks in walls, floors, or foundation.

2. Identifying the Root Cause

• The cause of the voids beneath your foundation may vary, but common causes include:
  • Soil Erosion: Excess moisture or improper drainage can erode the soil beneath your foundation, creating gaps.
  • Poor Soil Compaction: If the soil was not properly compacted during construction, voids may develop over time.
  • Water Damage: Groundwater infiltration can cause soil displacement and create voids beneath the foundation.
  • Settling: As the soil beneath the foundation shifts or compresses, voids can form and destabilize the structure.

3. Custom Void Filling Plan

• After assessing the site and identifying the cause of the voids, we create a custom plan for Void Filling. Our approach typically involves:
  • Polyurethane Foam Injection: Injecting expanding foam beneath the foundation to fill voids and stabilize the soil.
  • Grouting: Using a grout mixture to fill larger voids and provide additional compaction to the surrounding soil.
  • Soil Stabilization: In cases of significant soil instability, we may use techniques like compaction grouting or soil mixing to strengthen the soil before filling the voids.

4. Implementation of Void Filling

• Once we have developed a plan, we begin the Void Filling process. This may involve:
  • Drilling small injection points into the foundation to inject foam or grout beneath the surface.
  • The injected material expands to fill the voids and stabilize the surrounding soil, lifting and leveling the foundation in the process.
  • In some cases, we may use additional stabilizing techniques to ensure the long-term stability of the foundation.

5. Final Inspection and Follow-Up

• After the Void Filling process is complete, we conduct a final inspection to ensure that the voids have been completely filled and the foundation is level and secure. We also offer follow-up services to monitor the foundation and prevent future issues.
