Chemical grouting is a very cost effective method to stop infiltration into leaking pipes and structure walls identified during the inspection process. Either Acryladmide, Acrylic, or Urethane types of grout can be used depending upon the application. For pipe joint grouting, a packer device is winched into place over the joint using a closed circuit camera to line up, and the packer is then remotely inflated to test and/ or seal the joint. Large diameter pipes and structures can be grouted by drilling injection points and then pumping the chemical grout outside to seal the leaks.
