Epoxy injection is a repair technique used to fix cracks in concrete structures. It involves injecting a specially formulated epoxy resin into the cracks, which then hardens and bonds the concrete together. This method is effective for restoring the structural integrity of buildings, bridges, and other concrete elements. The process typically starts with cleaning the crack and preparing it for injection. Small ports are then installed along the crack, allowing the epoxy to flow into the damaged area. Once the epoxy cures, it creates a strong, waterproof seal that helps prevent further damage and extends the lifespan of the concrete.
