How Void Filling in Key Largo, FL Works
Void Filling is an essential process for stabilizing foundations, concrete slabs, and other structures that have developed empty spaces or voids beneath them. These voids often form due to soil erosion, settling, or improper compaction. Over time, the existence of these voids can cause slabs to sink, tilt, or crack, resulting in structural damage. Void Filling in Key Largo, FL involves filling these gaps with a stabilizing material to prevent further movement and restore the integrity of the structure.
At Key Largo Foundation Repair, we use polyurethane foam injection as the primary method for Void Filling. This technique involves injecting high-density foam into the voids, where it expands and hardens, filling the empty spaces and compacting the soil beneath the structure. The process is quick, non-invasive, and highly effective for both small and large voids beneath concrete slabs, foundations, and driveways.
Key steps in Void Filling include:
- Inspection: A thorough assessment of the structure to locate and measure the size of the voids.
- Drilling Access Points: Small holes are drilled into the surface to allow for the injection of foam.
- Injection: High-density polyurethane foam is injected into the voids, where it expands to fill the empty spaces and stabilize the structure.
- Sealing: The access points are sealed, and the worksite is cleaned, leaving the structure level and secure.
With Void Filling in Key Largo, FL, homeowners can prevent further damage caused by voids beneath their foundations or concrete slabs.

What to Expect During Void Filling in Key Largo, FL
The Void Filling process is straightforward and minimally invasive, making it an efficient solution for homeowners dealing with voids beneath their concrete structures.
Here’s what to expect during Void Filling in Key Largo, FL:
- Initial Inspection: Our team at Key Largo Foundation Repair will assess the affected area to determine the size and location of the voids beneath the structure. We use specialized equipment to identify voids that may not be visible from the surface.
- Drilling Access Points: Once the voids are located, small holes (about the size of a dime) are drilled into the surface. These access points allow us to inject the polyurethane foam into the voids.
- Foam Injection: High-density polyurethane foam is injected through the access points. The foam expands rapidly, filling the voids and compacting the soil beneath the slab or foundation. This process lifts and levels the structure while stabilizing the ground.
- Sealing and Cleanup: After the voids are filled and the structure is leveled, the access points are sealed, and the worksite is cleaned. The entire process can be completed in just a few hours, depending on the size of the project.
- Final Inspection: After the Void Filling process is complete, we conduct a final inspection to ensure the structure is stable and level. We also provide homeowners with a detailed report of the repairs performed.

Cost of Void Filling in Key Largo, FL
The cost of Void Filling in Key Largo, FL depends on several factors, including the size of the voids, the extent of the settlement, and the amount of foam required. While Void Filling is often more affordable than other foundation repair methods, it provides long-lasting stability.
Factors influencing the cost of Void Filling include:
- Size and Location of Voids: Larger voids or those located beneath hard-to-reach areas may require more foam and labor, which can increase the overall cost.
- Extent of Settlement: If the structure has experienced significant settlement or shifting, more foam may be needed to stabilize and lift it, affecting the cost.
- Materials Used: High-quality polyurethane foam is used for Void Filling, and the amount of foam required will impact the total price.
