Concrete crack injection can be used in a variety of ways to repair structural cracks or for waterproofing purposes. AWS can provide a tailored solution to your concrete crack requirements for a cost effective price.

Epoxy Resin Injection

Epoxy injection for Concrete Crack Repair in foundations, basements, beams, columns, slabs, walls and other concrete structures. Injection of epoxies under pressure may be used to bond the cracks being greater than or equal to 0.05mm opening. This method is not applicable if the crack is active, the cracks are large in number, or when the water leakage cannot be controlled. If the cause of the cracking has not been corrected, it will reoccur near the original crack. Extreme caution must be exercised when injecting cracks that are not visible on all surfaces. Epoxy Injection is the single best solution for repairing cracks in concrete. AWS Services utilizes a wide variety of high-strength epoxy and urethane resins which get injected into the cracks under pressure by special pneumatic machines. This system ensures that the crack will be thoroughly filled with epoxy, making the crack not only structurally sound but preventing water intrusion and subsequent spalling.

Polyurethane Injection for Repairing Concrete Cracks

Polyurethane is a fluid resin which is injected into concrete cracks, rock fissures, expansion joints and other voids in solid underground structures. When used in concrete crack injection applications the polyurethane is injected into a crack; within minutes the polyurethane undergoes a chemical transformation from a liquid to a solid. The versatility, and consequently the popularity, of polyurethane resins in crack injection applications stems from polyurethane’s properties:

  • It has a very short cure time, making it ideal for urgent water stopping
  • The resin cures normally whether a foundation crack is wet, actively leaking, or dry
  • There are literally thousands of polyurethane resin formulations which is useful when repairing foundation cracks because the viscosity of the resin and cure time can be controlled
  • Polyurethane, once cured, can be quite flexible depending on the formulation.
