What it is
A leak detection system is a network of sensors permanently installed within an inverted roof assembly. For building owners and managers, a leak detection system offers live data on the integrity of the waterproof membrane, allowing for targeted repairs and peace of mind for tenants, ultimately maximizing the useful life of the roof.
How it Works
During construction, sensors are installed on top of the waterproof membrane in a grid, then covered by layers of insulation and overburden.
The sensors are connected to advanced electronics which actively record measurements and upload data to the cloud for review. SMT uses proprietary algorithms to produce a membrane health assessment report, which building owners can use to plan/defer maintenance.

Quality Assurance
During Construction
While installing a Leak Detection System on an inverted roof assembly, SMT technicians also perform a Digiscan Service - an electronic leak detection scan of the membrane to confirm it has been installed without defects. This allows the construction team to move forward with confidence that they are covering an intact waterproof membrane. FutureCast Active can be used immediately after the membrane has been covered to confirm the status of the waterproofing.
