Pressurized injection is used exclusively for poured concrete foundations and structures. Pressurized injection involves either epoxy or polyurethane resin and is used for the repair and waterproofing of cracks, holes, or cavities in foundation walls, from inside the home almost exclusively. Pressurized injection especially, is a waterproofing method that requires technicians to possess considerable skill, experience and tenacity.
- Polymer Injection Grouts: – Polymer injection grouting is based on use of polymers such as polyester, epoxy, vinyl ester, polyurethane and acrylic resins. The most popular polymer used for epoxy grout is epoxy. Polyurethane and acrylic resin based polymers are used for treatment of water retaining structure, underground structures as well as to prevent seepage of water.
- Fiber-reinforced injection grouting: – Fiber reinforced concrete is used for repair of concrete and masonry structural members. Fibers such as polypropylene, Steel or Glass fibers are used with Portland cement or shrinkage compensating mortar to repair and strengthening of structural members to provide improved flexural strength, impact resistance and ductility. Fiber reinforced injection grouts require skilled handling to avoid segregation of fibers.
- Cement – sand grouting: – Cement-sand grout is the most popular type of grout used for repair of concrete or masonry structure and is easily available. This grout is used for the places where strength enhancement of structure is not required. This method requires high water and cement contents for injection purpose. The use of cement-sand grouts results in shrinkage and cracking of grout at hardening and to minimize this, suitable shrinkage compensating agents are required. Use of cement-sand grouts is very common in masonry buildings, but not very common in concrete.
- Concrete Repair and Protection:- Concrete repair is the process of fixing a hardened concrete surface that over time has lost the ability to hold the binding concrete materials together due to damage or environmental exposure. Concrete repair is appropriate for cracks, physical impacts, chipped out surfaces or surface scaling.
