Rooftop leak sensor

Case info Year: 2020
Location: Australia
Technology: Leak Sensing

Pilot leak sensing installation on rooftop.

Imagine installed a first pilot of its graphene enabled leak and moisture sensor on a rooftop of a high rise building.

“Moisture ingress in buildings represents one of the single most significant issues any building owner, operator or REIT Real Estate Investment Trust faces. Moisture includes internal humidity issues, ground water rising, or external penetration. The problem is a 13 billion US dollar issue in the United States alone.”

This was our first live pilot where we solved the customer problem by introducing a large sensor system into the rooftop. Design of the solution took 3-4 weeks and was done in close iteration with the customer. However, several decisions were made in a very pressed schedule due to late introduction of the solution during the construction process.

Graphene sensing layer has been installed within the roof construct providing real time moisture information from the entire surface. If water is able to penetrate the waterproofing layers the moisture is reflected through real time measurement and after reaching a pre-defined tolerance level an alert is triggered. The alerts are displayed instantly in real time and a detailed inspection of the exact location can be performed on site to remediate the problem. The solution consist of imgne X3 graphene coated geotextile layer inside of the roof construct connected to imgne F3 device through cables running on the edge of the roof. The F3 is placed in a secure cabin on the site and collects continuous moisture information passing data to cloud through WLAN connection.

Accuracy can be defined jointly with the customer. This system is following 14 pixels on the roof but the size and number of pixels can be decided for the customer need. There are few uncovered areas left intentionally due to children playground construct and related structures on the rooftop.

In general, the roof can be any surface, such as tiles, metal sheeting, membranes, wood or concrete. Underneath that outer layer, the imgne X3 sensing layer will detect imperfections of installation, aging, damage due to weather, maintenance or modifications. Any leak can be detected in real time, located and a prioritised alert sent. The application of the imgne X3 technology is very flexible and it can be incorporated into nearly any roofing or sub-roofing material, such as breather membranes, insulation and even on the underside of the external weatherproof surface.
