Challenge
A homeowner in Manassas, VA, contacted Fortress Foundation Solutions about cracks and uneven areas in their garage floor. They wanted a solution to level the slab and repair the damaged concrete.
Solution
Foreman Ethan and David injected 98 pounds of PolyLevel® foam at various points beneath the garage slab to lift and level the concrete. They then sealed the cracks with NexusPro®, helping prevent water from entering through the cracks and contributing to further soil erosion beneath the slab.
