Epoxy Injection
Epoxy Injection is primarily used to repair cracks in structural concrete in the process restoring structural integrity while preventing ingress of moisture. The process involves sealing of the crack surface with an epoxy paste followed by the injection of low viscosity two part resins through ports placed strategically on the surface of the crack. More recently epoxy injection has been utilized in historic wood elements where restoration and preservation as opposed to replacement is preferred. The types of epoxy, equipment utilized and the method of repair is dependant upon the application.
The experience, knowledge and approach adopted by the applicator is also a key component in the success of the project at hand.
Chemical grouts are primarily used to seal cracks and penetrations in below grade structures where the ingress of moisture is evident and access cannot be obtained, externally, to install conventional waterproofing. Typical applications include defects in foundations, dams, waste water treatment facilities and in more recent times geo technical applications such as soil stabilization. Key factors in obtaining the desired results include selection of the correct materials and a thorough understanding of the problems that exist.
