Epoxy Injection
Epoxy Injection is a repair method used in construction and waterproofing to fix cracks in concrete structures like foundations, walls, and floors. It's like using a special super-strong glue that's forced into cracks to seal them and make the structure watertight again. This method is popular because it not only stops water from coming in but also makes the concrete strong again. Companies often look for professionals who know how to properly prepare the surface, mix the materials, and use the injection equipment. It's a key skill in the waterproofing and concrete repair industry, similar to other repair methods like hydraulic cement application or crack routing and sealing.
