Sometimes poured foundation cracks cannot be properly or permanently repaired with polyurethane injection alone due to inherent weaknesses and alternate methods need to be employed.
Repair of structural crack in poured foundation wall.
Material Used: Fortress 6k Carbon Grid Structural Surface Seal with Fortress #4060 Structural Foam
The combination of continuous carbon fiber set in Fortress #4020 epoxy gel combined with the injection of structural hydrophobic polyurethane foam (which has a compression strength of 2,000 psi) solves the problem of any weakness of polyurethane injections alone.
