Challenge: Cracked and Shifting Slab at Belle Grove Maintenance Facility
The Belle Grove Maintenance Facility in Middletown, VA, had long been operational when significant problems arose with its concrete floor. Deep cracks and shifting had created uneven surfaces, posing safety risks and threatening the building’s foundation. As the floor continued to settle, more damage was expected. The National Park Service (NPS) sought solutions from several contractors. Replacing the slab was an option, but it would be costly and cause long disruptions. Temporary fixes were also considered but wouldn’t solve the core issue. Founders waterproofing provided the ideal solution: injecting high-density polyurethane foam to fill voids, lift the slab, and seal all cracks with Polyflex, ensuring long-term stability and protection against future damage.
Solution: Polyurethane Foam Concrete Lifting in Middletown, VA
We implemented several systems to resolve the concrete slab issues at the Belle Grove Maintenance Facility:
-
- Assessment of the Slab Using a Precision Meter
We first assessed the extent of the slab’s shifting using a precision meter to identify the areas that required lifting. - Drilling Strategic Holes
Small holes were drilled into the slab to prepare for the foam injection. These holes were strategically placed in the most affected areas. - Injecting Polyurethane Foam
High-density polyurethane foam was injected through the drilled holes, which expanded to fill the voids beneath the slab. The foam lifted and leveled the concrete to its original position, providing a stable foundation. - Monitoring Slab Movement
We used a dial indicator to monitor the slab’s movement during the foam injection, ensuring precise leveling and optimal results. - Sealing Cracks with Polyflex
Once the slab was stabilized, we sealed all cracks with Polyflex, a silicone-based sealant that prevents moisture from entering and causing future damage. - Clean-Up
After the repair work was completed, we cleaned up the site, removing all debris and ensuring the facility was ready for immediate use.

Outcome: A Stable and Reinforced Foundation
The Belle Grove Maintenance Facility has a stable, level, and safe concrete slab. The polyurethane foam concrete lifting ensures that the slab will remain stable for years to come, and the Polyflex sealant will protect it from future cracks and moisture damage.
