How it Works

FutureCast on Conventional Roof assemblies use resistance-based measurements to determine the presence of moisture below the waterproof membrane on the conventional roof assembly.

The FutureCast grid is made up of moisture sensors laid out in strips which are sensitive to the presence of moisture and are therefore triggered when water is allowed to accumulate inside the roof assembly.

Protection Board

Conventional Roof

Membrane (EPDM, 2-ply SBS, BUR, TPO, PVC, or single ply)

Insulation (Polyiso, EPS, XPS, or mineral wool)

moisture sensor tape

Moisture Detection Tape (MDS)

Air Barrier

Roof Deck (wood, metal, or concrete)

Augmented Reality

FutureCast Active enables cutting edge data visualisation - allowing maintenance teams to "see through" the membrane in real time, as the moisture sensors in the roof assembly show where moisture has accumulated. This aids repair efforts and cuts down on costly removal of the upper layers of the assembly. 

Virtual Reality

The same roof performance data can be viewed in Virtual Reality right from your desktop, so you can keep track of large and remote sites without leaving the office.
