Failing manholes in Edmonton and tiny Yukon community treated with Permacast and Centripipe spray liners by AP/M Permaform

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:

  • Six failing manholes in remote Carmacks, a Yukon village.
