Leak Detection Systems for Inverted Roof Assemblies

FutureCast Active is SMT's Leak Detection System for inverted and protected roof assemblies. It enables non-destructive monitoring of the roof assembly, saving time and reducing the scope of costly tear-up during a leak inspection, ultimately limiting inconvenience to tenants and disruption to business. 

FutureCast can also be left in a passive state, to be activated on a service plan or call out. 


With FutureCast, you can;

+ Receive Live intelligence on the health of your waterproof membrane

Calibrate alarms for developing issues

Reassure Occupants and Tenants 

Get the most out of your Roof Warranty

FutureCast Leak Detection

How It Works

SMT uses trend data to distinguish between actionable events and structural or electrical false positives (HVAC interference, active site work, power outages, etc.). The more seasonal reading that are taken, the more accurate our analysis, therefore FutureCast Active provides the most accurate information.

Exact layout dependent on building topology and specified granularity.

Clear Deck with Membrane

The Roof Deck is cleared of any debris to prep for system install. 
When installing the network, technicians will account for all anchors, drains, vents and other deck obstacles as encountered.

EFT Grid Applied

Inverted Roof Systems are always wet, SMT uses Electrical Field Tape (EFT) to electrify the roof deck in search for membrane breaches. It is applied to the upper surface of the waterproof membrane and defines the area that we monitor.

Digistar Sensors Placed

The grid is then fitted with Digistars, a sensor which uses the electricity provided by the EFT.

In the event of a leak, Digistars will work with EFT to point to a deficiency in the membrane and identify where there is a path of moisture leading to the protected steel or concrete substrate.

Data in your Pocket

Always have access to your roof performance data with SMT Analytics. Check sensor output and system function, as well as view historical data and documentary photographs from construction - an invaluable aid to leak repair. 

SMT engineers are on hand to assist you with email or phone support if required.

FutureCast Passive

Installing a full grid and sensor system for eventual use when the roofing system deteriorates or is damaged resulting in a discovered leak. 

SMT technicians can provide temporary electronics for a yearly or periodic maintenance scan.

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.
