Epoxy concrete repair is an industrial-strength, two-component adhesive that permanently bonds concrete and creates an extremely hard surface that is stronger than the concrete itself. It won't shrink or crack, and it can be used to make repairs that are both neat and durable with minimal waste. Epoxy is an adhesive used to bond concrete structures, and it can be found in the form of coatings, repair materials, grouts, paints, bonding agents, sealants, wearing surfaces and more. It is often used as an admixture in hydraulic cement concretes to make epoxy polymer-modified concrete.
The procedure for epoxy concrete repair varies depending on the location of the crack and whether it is horizontal or vertical. You may encounter some problems during the process that require your attention to complete a clean concrete injection repair. For example, the crack may be too large or there may be a large amount of water in the crack that cannot be removed. SCT-EP can be used prior to the application of a concrete coating or as a stand-alone crack treatment.
Using epoxy to repair concrete cracks requires knowledge and skill. Before fixing the crack with epoxy, you must first determine if this is the right method. It can be done with mild or aggressive measures as long as the concrete structure is not affected. Injecting the concrete filler as close to the crack as possible may be necessary, so you will have to go quite deep into the crack.
There are two types of epoxy that offer the best surfaces for concrete and a thick, challenging and attractive finish. The material presented in epoxy resists water flowing from it to repair concrete cracks, so there is no leakage. Most concrete cracks are related to shrinkage, heat, improper joint placement, excessive stress and loading conditions and movements caused by external factors. While no crack can be truly repaired, SCT-EP serves as a wonderful treatment product to help reduce shading through those cracks into the next layer of decorative coating or overlay product, as well as to minimise the amount of movement and subsequent cracking of the same location in your concrete slab.
Ensure that the surface is properly cleaned before beginning any repairs, leaving no residue, dust or dirt behind.
