When you have a crack that needs to be structurally repaired and the area needs to be as strong or stronger than the concrete around it, epoxy resins are the perfect choice.
Epoxies for crack injection are available in a range of viscosities to accommodate cracks of different widths. The wider the crack, the thicker the material required.
The main advantage of using Huntsman epoxies is their amazing compressive strength, which at 12,000 psi or greater, exceeds that of most concrete. That's why epoxies are the only choice for cracks requiring structural repair.
