Epoxies are always the preferred material when the structural integrity of the concrete is open to question. Two-component epoxies, which effectively seal a crack and at the same time reinforce the repair area to be actually stronger than the un-repaired concrete area around it. With this crack repair method you accomplish several objectives at the same time: you are waterproofing your basement, you are structurally repairing a foundation crack, and you are preventing the possibility of a future basement leak from the repaired crack.ДЎ. This process is repeated until the injected epoxy is seen exiting the crack at the top of the foundation, or until the crack has been filled up to grade. The technician begins the epoxy crack injection through the lowest injection port until epoxy travels up the crack and becomes visible in the injection port immediately above it then the lowest injection port is capped-off and epoxy is injected into the port immediately above it. At the same Epoxy Injection Crack Repair time the nozzles are positioned and fixed along the entire length of the crack, at approximately 20 cm intervals, with the same material. Strengthening is provided by installing additional reinforcement across the failure plane in combination with the resin injection. The chemical expansion of the polyurethane (typically 5-10 times its original volume) makes polyurethane very effective at filling voids within the concrete these voids are typically invisible when you look at the wall and are often associated with the porosity of the concrete. Any crack in your foundation is never a good thing.
