Injection repair techniques. Most existing structures are only accessible from one side; injection repair allows for efficient and effective waterproofing and repair in these cases. Epoxy and cementitious injection repair used for structural requirements in existing civil designs. Polyurethane injection repair is used in the areas of waterproofing where flexibility is required and cracks are non-structural. Acrylic gels are used to form a membrane to the exterior of a structure where access is not possible. Acrylic gels can also be used for ground stabilisation

Polyurethane Injections or grouting are often use for the repair of structures, concrete elements or sealing components, where fast reaction is necessary. The range can varies from a convenient one component resin for small water sealing jobs to specialist robust multi-component systems to effectively stop massive water ingress problems.

Many of the products for preventing water ingress can be adjusted on site to give varying performance properties to suit the conditions using different accelerators, which requires a high demand on experience, material know-how and equipment technology. Additional requirements on health/safety and durability aspects have to be considered. We offer its service in a wide range of application fields, like.

Cracks in concrete are filled by injecting a low viscosity epoxy resin into the crack. The epoxy resin is injected under pressure which allows it to penetrate the full depth and path of cracks. Providing complete crack repair, not only the crack sealed structural strength is gained as the epoxy resin is much stronger than the original concrete.

Epoxy high tensile and bonding strength prevents further elongation and yawning of structural cracks. However the cause of the structural stress itself must be determined and resolved in order to assure proper repair. Our Personnel, equipment’s and product partners have allowed us to provide epoxy injection service on an array of bridges, buildings, storm drains and many other concrete structures.

Normal cement grouting is done for filling the gaps, increasing the strength & impermeability of the RC member, reduce the porosity of honey comb members. It is also used to correct faults in concrete and masonry structures Pressure grouting involves injecting a grouting material( cement: admixture: water) into otherwise inaccessible but interconnected pore or void space of Rcc structure.
