Void Filling Services in Big Sandy, TX

The Void Filling process involves identifying the voids beneath your foundation, determining the underlying cause, and using specialized materials to fill the cavities and stabilize the ground. Here’s a step-by-step overview of how the Void Filling process works:

Step 1: Site Inspection and Assessment

• We begin by thoroughly inspecting the affected area, checking for signs of settling or shifting. Our team looks for visible cracks in the foundation, uneven floors, and doors or windows that are difficult to open or close.
• Using advanced tools like ground-penetrating radar (GPR) and laser leveling, we assess the extent and depth of the voids beneath the foundation.
• We also evaluate soil conditions, moisture levels, and drainage systems around the property to understand the cause of the voids and prevent future issues.

Step 2: Identifying the Cause of the Voids

Voids can form for a variety of reasons, including:

• Soil Erosion: Continuous water movement, poor drainage, or plumbing leaks can wash away soil, creating voids beneath the foundation.
• Soil Compression: Poor compaction of soil during construction can result in settling over time, leaving voids under the foundation.
• Water Intrusion: Accumulated water from inadequate drainage or plumbing leaks can erode the soil, leading to gaps beneath the foundation.
• Natural Soil Shifting: In areas with expansive clay soils, the ground can shift due to moisture changes, creating gaps or voids beneath the foundation.

By identifying the underlying cause, we can select the most effective approach to fill the voids and stabilize the soil beneath your foundation.

Step 3: Selecting the Right Void Filling Method

Once we’ve identified the cause of the voids, we select the most suitable Void Filling method for your specific needs. Common techniques include:

• Polyurethane Foam Injection: This technique involves injecting polyurethane foam into the voids beneath the foundation. The foam expands to fill the gaps and hardens, stabilizing the soil and lifting the foundation.
• Grouting: We may use a cement-based grout to fill larger voids or cavities. The grout is injected into the soil and fills the space, hardening to provide long-term stability.
• Soil Stabilization Injection: For areas with loose or soft soil, we inject stabilizing agents that bind soil particles together, preventing further erosion and reinforcing the foundation.
• Compaction Grouting: This method involves injecting a grout mixture into the soil, which compacts the surrounding soil and fills the voids, restoring strength and stability to the foundation.

Each method is selected based on the type of void, the soil conditions, and the degree of foundation damage.

Step 4: Void Filling and Stabilization

After selecting the right technique, our team begins the Void Filling process:

• Injection Process: If using foam or grout, we drill small holes in the foundation or surrounding areas to inject the material into the voids. The material expands or flows into the cavities, filling them completely.
• Compacting and Lifting: In some cases, we use compaction grouting or other methods to lift and stabilize the foundation, ensuring it’s level and secure.
• Continuous Monitoring: As the material is injected, we monitor the process to ensure that the voids are fully filled, and the ground is stabilized.

Step 5: Final Inspection and Clean-Up

Once the voids are filled and the foundation has been stabilized, we perform a final inspection to confirm that the repairs are successful. We check for any signs of further settling and ensure that the foundation is secure.

• We then seal the injection holes and clean the site, leaving your property in excellent condition.
