Epoxy Injection Services
Expert Solutions to Strengthen Structures and Improve SafetyEpoxy crack injection is a structural concrete repair method that bonds cracks to restore monolithic strength. Using a two-part, high-strength resin, this technique fills cleaned cracks with precision using a calibrated injection machine. While it offers a cost-effective alternative to concrete replacement, it addresses existing damage—not the root cause. Proper crack cleanin is essential for effective results.
Epoxy pressure injection is a repair to an existing condition. It is not a solution to the cause of the problem!
Additional consideration for every application:
- Inspect concrete integrity, surface temperature, moisture and crack contamination. Epoxy injection resins will not cure properly when introduced into the presence of water inside or weeping of moisture out of crack.
- Identify and solve the cause of the crack
- At periodic intervals, conduct sample testing of the machine injected resin to verify correct mix ratio and that samples have cured properly. Samples should be labeled and retained for QA/QC
- Select resin viscosity that is compatible with the width, depth, and size of the crack. Industry standards do not recommend injection of cracks wider than 3/8”
- Mechanically roughen length of concrete surface on each side of the crack to ensure epoxy paste bond. Use cap paste with excellent bond and create a positive seal.
- Select proper methods for removal of epoxy cap paste and ports to ensure the best possible aesthetic finish.
