Inspection and Repair of Grouted Tendons
Special Products - Half Pipe
DSI's half pipe is the perfect solution for cracked or cracking HDPE external grouted ducts. Developed to be installed in difficult access contitions, the Half Pipe snaps into place over an existing HDPE duct and has been engineered so that the annular spaces can be pressure grouted, restoring the tendon to its original corrasion protection specifications.
The DSI Half Pipe also allows for the complete removal of the existing HDPE pipe to assess the condition of the grout and strands, if required, prior to its installation.
