LEAKING & STRUCTURAL CRACK REPAIR
CPR Services are market leaders in leaking and structural crack repair by way of injection. Utilising epoxies for structural crack repair and polyurethane and acrylic resins for leaking crack repair, 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 the specification.
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, active 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..
STRUCTURAL CRACK INJECTION – EPOXY
Low viscosity epoxy crack injection & repair is used as a structural crack repair method. CPR has developed the latest technology to inject using proven systems which allows us to ensure the crack/void is repaired to clients’ requirements.
CPR typically use these systems on:
- bridges
- reservoirs
- roads
- tunnels
- floor and post-tension slabs
- other load bearing concrete assets
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 and we are continually referred to clients and authorities requiring the highest standards.
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.
LEAKING CRACK INJECTION – POLYURETHANE
Polyurethane crack injection is the most effective leaking crack repair method in concrete.
CPR Services offer structural leak repairs with Crack Injection on domestic / residential, commercial and civil constructions and sites. We are the most recognised and engaged for crack injection work on civil and commercial structures and are well equipped to handle leaking crack injection regardless of the size of the project.
CPR typically undertake polyurethane crack injection on:
- Civil Water – treatment plants, town water supply, pump stations, channels, canals
- Sewage Treatment Plants – high voltage electrical pits, man holes, chemical storage areas
- Dams – diversion tunnels, dam walls, permanent plugs, dam walls, weirs
- Tunnels – rail, road, access and electrical
- Underground Structures
