Epoxy injection is permanent repair that is both a structural repair and a structural preservation procedure. The epoxy injection process not only fills cracks, but welds them together structurally with an epoxy material that is forced through cracks under pressure forming a bond that is stronger than the concrete itself.

Quality of workmanship in epoxy injection is critical, since no one can see if a crack is completely injected. Critical job site considerations include proper surface preparation, method of capping and porting, injection material, method and pressure selection, and results confirmation.
