A tale of two manhole fixes

Canadian contractors are cost effectively rehabilitating failing manholes and sewers without excavation or barrel replacement using the Permacast and CentriPipe systems developed by AP/M Permaform (AP/M) and distributed by Martech, Inc. Edmonton-based OSCO Mudjacking & Shotcreting Ltd. applied Permacast on two manhole projects with widely varying challenges:

  • A new 9-metre manhole installed as part of Edmonton’s massive project converting the QE II Highway and 41 Avenue SW connection to a grade-separated interchange.
  • Six failing manholes in remote Carmacks, a Yukon village.
