RST helix Advanced Manhole Survey System

With all the innovations for inspection and rehabilitating existing infrastructure, Mar-Tech is dedicated to learning all about emerging technologies. The RST helix Advanced Manhole Survey System Mar-Tech uses is the first of it’s kind in Canada and allows for detailed computer inspection of manholes and other interior chambers.

Inspection of a deteriorating manhole is instrumental in planning for it’s rehabilitation. Manholes often are replaced during open cut pipe installs, but for lining purposes, a more creative way of manhole rehabilitation takes place. After a thorough inspection, all deficiencies must be repaired, including ladder rungs and broken or missing sections. Once the structure is sound various methods of resurfacing or lining the manhole can take place.
