The problem
During the original construction of this Purchase, NY home, the foundation cracked before the build was complete. The original builder injected an improper material into the crack and assured the owner the foundation was sound. Four years later, the homeowner discovered a significant leak. When the wall was opened up, the original crack was found to extend across the entire home, the failed builder repair had only masked the symptom for a few seasons.
How we fixed it
Full restoration: we performed structural masonry repair across the entire crack length using a high-modulus material superior to the original concrete, applied carbon fiber + Kevlar reinforcement bands across the affected wall, and installed a complete waterproofing system on both the interior and exterior wall faces. The wall now performs structurally as a continuous element and is fully watertight, with our lifetime transferable warranty.
