Manhole Assessment and Rehabilitation: Canadian Construction Association (CCA) Gold Seal Accredited Course


Location: Mississauga Grand, 35  Brunel Road, Mississauga.

Canadian Construction Association (CCA) Gold Seal Accredited Course 

This workshop presents the inspection and trenchless rehabilitation methods for maintenance of holes. It addresses the growing problem of manhole deterioration. Inflow and infiltration solutions have been discussed extensively for sanitary and storm sewers. However, these measures may be limited if manhole chambers are neglected. Consequently, an increasing amount of attention has been paid to the rehabilitation challenges facing sewer maintenance holes. As in other aspects of the sewer systems where trenchless technologies are replacing excavation, this seminar will highlight the inspection and trenchless rehabilitation methods for maintenance holes.
