To get an idea of why Epoxy Injection And Carbon Fiber Fails Every time, and why they are bad choices for concrete repair, you need to take a brief on the most misunderstood thing about concrete.
Concrete, once poured, is often considered unmovable; a massive slab that will just say there and exist forever to provide a patio, a driveway, a foundation or even as a shell for a swimming pool. This couldn’t be further from reality. Yes, concrete is hard and seems pretty solid but the make-up of concrete and how it exists once it’s poured is relatively complex.
Due to the effects of expansion and contraction of the concrete and weather changes, where hot and cold cycles, as well as wet and dry cycles all affect the concrete, cracks can occur. While under normal circumstances, the chemical make-up of concrete is made to withstand multi-directional movement, the combination of extreme circumstances, and how it was mixed and installed originally can lead to cracking.
Once these literal tons of concrete begin to crack, it is imperative that the crack be stabilized properly with torqued resistance to stop the movement in the crack and to make permanent repairs that stop the potential of water seepage, leaking or ongoing deterioration of the materials.
Where some homeowners will opt for epoxy injection as a repair method, the single guarantee that offers for the life of the concrete is that it will fail to adhere and prevent water loss and leaking, spreading of the crack or shearing of the concrete. This isn’t necessarily due to the epoxy mixture, though the application of epoxies on vertical walls is completely flawed (more on that later), it’s the concrete itself that doesn’t allow for epoxy to provide a solution. Concrete itself doesn’t just break – it fractures. By administering an epoxy into the crack, the misguided belief that epoxy will stretch and stick to the edges of the crack is flawed. Epoxy dries. Concrete continues to shift and move. Inside of the epoxy, as a dried entity, small cracks and fissures occur, causing a failure to stay together as a solid, and as even the slightest movement of concrete occurs, those tiny separations inside of the epoxy split and what epoxy that did adhere to the inside of the cracks remains stuck to it and the epoxy itself separates and moves with the concrete, creating yet another crack down the middle of the epoxy.
