Our purpose built delivery methods surpass any other injection system in the market place and ensure the product is delivered into the crack as per specification. Our extensive supply chain network consists of the most advanced epoxy resins on the market. CPR Services is a preferred installer/applicator for most of the largest resin suppliers in Australia andwe are continually referred to clients and authorities requiring the highest standards.

Low viscosity epoxy crack injection & repair is used as a structural crack repair method. CPR has the latest technology to inject using proven systems which allows us to ensure the crack/void is repaired to clients’ requirements. CPR typically uses these systems on bridges, reservoirs, roads, tunnels, floor and post tension slabs and any other load baring concrete asset.

Injection is typically used on horizontal, vertical, and overhead cracks where conventional repair methods cost prohibitive. Prior to proceeding with a crack repair by epoxy injection, the cause of the crack and the need for a structural repair must be determined. If the crack does not compromise the structural integrity of the structure, injection with polyurethane grouts or other non-structural materials may be a more suitable choice to fill the crack (ie Leaking, flexing etc). When a structural repair is required, conditions that cause the crack must be corrected prior to proceeding with the epoxy injection. If the structural crack is damp and cannot be dried out, a moisture tolerant resin must be considered. Alternatively if the crack is non-structural a low viscosity polyurethane hydrophilic resin would achieve the best result.

Epoxies for crack injection are available in a range of viscosities, from ultra-thin to paste-like are used to accommodate cracks of different widths. The main advantage of epoxies over other repair products is their high compressive strength. That’s why epoxies are the only choice for cracks requiring structural repair.
