Details

SMT provided a roof scan on the new Manitoba Hydro building to commission 35,000 sq ft of green roof decks surrounding the main tower.  The sensor grid deployed on the roof can be used to detect future water leaks that may occur due to degradation or accidental damage.

A roof scan is a manual procedure that requires an SMT technician to test and evaluate the roof deck in order to pinpoint a potential penetration or leak. Typical evaluations are completed after the initial membrane and green roof components are installed.  The roof is then evaluated on a periodic basis or when a moisture penetration event is detected.

This installation was featured in the Fall 2007 Western Economic Diversification Canada Newsletter.

Due to the success of this project, SMT has been contracted to perform a variety of roof membrane evaluations which were the catalyst for further research into roof membrane leak detection. As a result of this research, SMT has designed a revolutionary leak detecting instrument for roof membrane systems.

Similar to the electric field method, where two poles are used to perform manual triangulation, a multitude of sensitive current measurements are automatically recorded by an integrated microprocessor that displays the direction and magnitude of the breach on an LCD display.
