    Chemical Grouting

    Chemical injections grouting method is used for the repair of structures, Tunnel face stabilization, sealing of concrete elements, with fast-reaction time as needed. Different types of polyurethane like single component, two component, Urea Silicate or Flexible foam are used. The range can vary from one-component resin for small water sealing jobs to customised technical properties multi-component systems to effectively stop huge water ingress. Depending upon site requirement to get varying performance can be achieved using different
    accelerators, which requires a high skill and experience, material know-how and equipment technology from the specialised applicator.
