The Challenge: Severe Erosion Creating Voids Under Stairway Slab
In Alexandria, VA, the Fasano family’s stairway exit had severe erosion that created voids beneath the concrete slab. These gaps affected the slab stability and displaced nearby pavers, posing a safety risk. Seeking an expert concrete repair solution, the Fasano family turned to LUX Foundation Solutions.
After assessing the damage, our team identified high-density polyurethane geotechnical foam as the best choice for concrete void filling foam. This approach would fill voids under concrete, stabilize the structure, and prevent further erosion.
Solution: High-Density Polyurethane Concrete Void Filling Foam
Our expert team implemented a concrete repair solution using polyurethane foam for concrete void filling. This durable foam injection method stabilizes the area while addressing erosion. Here’s how we applied concrete void-filling foam to restore the Fasano family’s stairway.
Step 1: Site Preparation and Paver Removal
Our team accessed the site through the back gate, carefully removing the pavers along the left side of the staircase to reach the void areas beneath the concrete slab. Working with Kingstown Lawn and Landscape, we ensured the surrounding landscape remained undisturbed as we prepared for the concrete void filling foam process.
Step 2: Filling Voids Under the Concrete Slab
To stabilize the main concrete slab, we drilled ½-inch holes at strategic points directly into the slab and injected high-density polyurethane foam into the voids beneath. This foam is designed to fill voids under concrete, providing critical support for the slab. This application reinforced the slab’s integrity without causing it to lift, ensuring it would remain stable and well-supported against future erosion.
Step 3: Filling Voids Within the Hole on the Left Side of the Staircase
In addition to the voids under the main slab, we also addressed the erosion issues within the hole on the left side of the staircase. Here, we injected high-density polyurethane foam directly into the hole’s interior to fill any voids and stabilize this section. This focused application of foam provided additional support to the pavers near the staircase and helped prevent further erosion, ensuring that both the slab and surrounding areas remained secure.
Step 4: Paver Resetting and Final Touches
Once the polyurethane foam for concrete had fully set and filled all designated voids, we added a paver base and sand beneath the removed pavers, further stabilizing the surface. The pavers were then reset, restoring the stairway’s original appearance and functionality. Finally, we sealed the drilled holes in the slab with patching cement, ensuring a polished and durable finish.
The Outcome: Stabilized Stairway Exit and Long-Term Erosion Prevention
With the high-density polyurethane foam injection complete, the Fasano family’s stairway exit is now securely stabilized and protected against future erosion. The concrete void filling foam restored the area’s safety, while the carefully reset pavers improved the stairway’s appearance. This project comes with a five-year warranty, ensuring confidence in the durability of the repair.
