The problem
Water was coming through a vertical crack in the foundation wall of a carpeted Stamford basement. The mineral staining and efflorescence streaking down from the crack showed this had been running for seasons rather than appearing after a single storm, and the remains of earlier surface patches were still sitting on the crack line where they had already let go. Rigid foam insulation had to be cut back to expose the full length of the break before the wall could be assessed properly.
How we fixed it
We prepped the substrate along the full run of the crack and injected it at full wall depth, stopping the water at its source instead of skinning over the face. Once the wall was watertight, we bonded carbon fiber reinforcement across the repaired section in structural epoxy, giving the wall the tensile capacity it was missing and keeping the crack from reopening under seasonal soil pressure. Injection ports were patched flush once the resin had cured.
