What is Void Filling?
Void Filling is the process of injecting material into the empty spaces or voids that form beneath foundations or concrete slabs. These voids can develop over time due to soil erosion, water intrusion, or natural settling, causing parts of the foundation or slab to sink or become uneven. If left untreated, voids can lead to further settling, structural cracks, and even collapse in severe cases.
The Void Filling process typically involves using specialized materials such as Polyurethane Foam or grout, which are injected into the voids to fill the space, stabilize the surrounding soil, and lift the foundation or slab back to its original position.

Signs Your Property Needs Void Filling
Identifying the signs that your property needs Void Filling is essential to preventing more serious foundation issues. If you notice any of the following problems, it’s important to address them promptly to avoid further damage:
- Sinking or uneven concrete: If your driveway, sidewalks, or concrete floors are sinking or appear uneven, it may indicate that voids have formed beneath the surface.
- Cracks in the foundation or walls: Cracks in walls, especially horizontal or stair-step cracks, can be a sign that the foundation is settling due to voids.
- Gaps between walls and floors: If you notice gaps forming between the walls and floors, it could indicate that the foundation is shifting due to voids beneath the surface.
- Bouncy or unstable floors: If parts of the floor feel unstable or bouncy, voids beneath the foundation may be causing this issue.
- Water pooling around the foundation: Water that pools near the foundation can erode the soil beneath it, leading to void formation and instability.

Causes of Voids Under Foundations
Voids beneath foundations and concrete slabs can form for several reasons, all of which require Void Filling to stabilize the area. Common causes include:
- Soil erosion: Water erosion from rainfall, irrigation, or poor drainage can wash away the soil beneath the foundation, leading to voids that cause settling and instability.
- Improper soil compaction: If the soil beneath the foundation wasn’t properly compacted during construction, it may settle over time, leaving voids and gaps beneath the surface.
- Water leaks: Leaks from pipes or sewer lines can lead to erosion and the formation of voids beneath the foundation.
- Tree roots: Large tree roots near the foundation can shift the soil and create voids as they grow, leading to foundation movement and settling.
- Natural settling: All properties experience some degree of natural settling over time, which can result in small voids forming beneath foundations and concrete slabs.

Our Void Filling Process
At Fort Lauderdale Foundation Repair, we follow a comprehensive process to ensure effective and long-lasting Void Filling results. Here’s an overview of how we approach void filling:
- Initial Inspection and Assessment
We begin with a detailed inspection of the affected area to assess the extent of the voids and determine the cause of the foundation settling. Our team uses advanced diagnostic tools to locate the voids beneath the foundation or concrete slab and develop a customized repair plan. - Customized Void Filling Plan
Based on the inspection results, we create a customized void filling plan tailored to your property’s specific needs. Depending on the size of the voids and the type of foundation, we may recommend using polyurethane foam or other grout materials to fill the voids and stabilize the foundation. - Drilling Injection Points
Small holes are drilled into the affected area to create access points for the injection process. These holes are strategically placed to ensure the material reaches all voids beneath the surface. - Injection of Filling Material
Using specialized equipment, we inject the selected material (usually polyurethane foam or grout) into the voids. The material expands as it is injected, filling the empty spaces beneath the foundation or concrete slab, stabilizing the surrounding soil, and lifting the structure back to its original level. - Monitoring and Adjustments
During the injection process, we closely monitor the movement of the foundation or slab to ensure that it is being lifted evenly and to the correct height. Adjustments are made as needed to achieve optimal results. - Final Inspection and Sealing
Once the voids are filled and the foundation or slab has been stabilized, we conduct a final inspection to ensure the area is properly leveled and free of any remaining voids. The small injection holes are then sealed, and the work area is cleaned up.
