How does epoxy injection work?

Epoxy injections are designed and used to restore the strength and integrity of structural elements in cracked concrete. If epoxy is injected into a leaking crack, water seepage can create channels through the epoxy, creating leaks in the new repair. Epoxy injection is the process of injecting an epoxy resin into cracks to essentially glue concrete back to its original state. It is an economical way to restore cracked concrete slabs and walls to their original structural design.

It is recommended to determine the root cause of the cracking and remedy that problem prior to injection to have a lasting repair. Epoxy injection is a resin-based sealant that is forced into cracks inside the concrete to prevent the rebar from being damaged and to prevent water from accumulating on the base. Cracks and weak reinforcing bars will cause the concrete base to weaken, which will make the affected building unsafe for occupation. The epoxy that is injected into cracks effectively seals them while allowing concrete foundations to retain their original strength and integrity.

Epoxy injection repairs are the only way to repair a cracked base without having to tear down the building and re-pour the concrete. Even if a crack isn't leaking now, water will eventually find it, says Lou Cole, president of Emecole Inc. Cole says that in the Midwest, crack injection has been an accepted way of approaching these repairs for many years, and more and more foundation repair contractors across the country are adopting the technique because it is cost-effective, reliable, and permanent. We have proven evidence that epoxy injection can restore the integrity of a structure and provide resistance to moisture penetration.

However, there are different serious situations in which helical piles, permeation grout and slab lifting together with epoxy injection may be more appropriate solutions. Epoxy crack injection (also known as epoxy injection) is an extremely effective and reliable concrete crack repair method, which is used exclusively for the repair of cracks of poured concrete foundations, for structural repair of them, for repairing leaks in the basement and for avoid cracks in poured concrete foundations. of leaks in the future. During this step, the injection technician will gain access to the crack in the base from inside the basement.

Hand tools that use a drive rod instead of a spring are difficult to control and can result in injection at pressures much higher than desired. Dual cartridge dispensing, which uses disposable or reusable cartridges or containers, is a cost-effective and completely portable method for injecting two-component polymers. If you have a structure that has suffered damage due to overload, vehicle impact, earthquake or any other “occasional” event, then you may consider using epoxy injection for your structural repairs. When this happens, you can block the port you are injecting from and move to the next port on the line.

Injection ports, which can be surface-mount ports or socket-mount ports, are the means by which epoxy resin will be delivered into the cracks. However, please note that the type of epoxy or polyurethane used and the time required for injection will vary with each job depending on the width of the crack, the thickness of the wall and other conditions. Epoxy injection starts at the lowest port for vertical applications and at the widest part of the crack for aerial or horizontal applications. Using low-pressure crack injection, foundation and basement crack repair kits seal basement cracks from the inside, eliminating the need to dig the ground from the outside of the foundation.

Civil engineers often recommend the injection of epoxy concrete cracks for structural repair of cracked concrete in applications such as road overpasses and elevated concrete structures; this is due to the high bond strength of epoxy. Epoxy injection is an exceptional repair method for simple cracks in a concrete foundation wall; and many other structural elements. For the repair of cracks in the concrete floor, there are certain epoxy and polyurea materials, suitable for such repairs of slabs. .
