Slabtec specialize in both Epoxy Injection and Polyurethane Injection. High strength structural epoxies are appropriate for stable cracks requiring a structural repair. Cracks can be reinstated with an epoxy typically having much higher compressive and tensile strengths than the concrete itself.
Low viscosity polyurethane resins are injected into cracks under high pressure and react to form a flexible foam. Where structural repairs are not required, polyurethane injection is commonly used to seal structures to prevent water ingress and passage.
