REHAU urges commercial building professionals to consider ultrasonic technology to end water damage woes

  • 18 May 2021

With water damage proving to be one of the most frequently reported insurance claims in buildings, the latest in ultrasound technology from REHAU offers a promising solution to avoid costly damage in vulnerable commercial buildings.

According to ABI, insurers pay out £1.8 million for residential water damage every day. Causes can relate to a number of issues such as corrosion, limescale and frost compromising old pipes, as well as accidental drilling of new systems, all of which can have disastrous effects in commercial buildings.

According to an expert at AXA, particularly vulnerable buildings include those that have just been built, vacant, or reduced occupancy – as are many buildings currently due to the pandemic.


REHAU recently unveiled a pioneering smart water control system using the latest in ultrasound technology – RE.GUARD.

With most drip-based leaks usually unnoticeable, and burst pipes then leading to severe damage, REHAU is encouraging specifiers, contractors and facilities managers to take advantage of this new prevention technology.

REHAU’s RE.GUARD smart control water system monitors the water flow rate assessing it in real time due to integrated software. The new system comprises four main components: a smart water controller, water sensors, a hub gateway and an app.


Water damage issues pose a higher risk in commercial buildings, such as offices, as they generally have more water features than residential homes, including more toilet facilities, air conditioning, water coolers, and coffee machines connected to the mains.

The RE.GUARD controller helps detect burst pipes and drip leaks by shutting off the water supply to mitigate damage. It is installed after the water meter, which allows it to also measure water consumption. It also has the ability to be manually turned on and off.

The controller is supported by RE.GUARD water sensors which detect leaking water in critical areas even faster by being positioned throughout the building. It connects to the RE.GUARD smart water controller via the Z-Wave radio standard and includes an extension cable for particularly difficult places to reach.

All devices are connected to the Internet via the RE.HUB gateway which can easily be connected to a building’s router. Essential information is then available to the property manager at a glance. This helps to identify sustainable ways to save on water consumption.

‘Exciting new gadget’

Steve Richmond, Head of Marketing and Technical at REHAU Building Solutions, comments: “Not only is water damage an expensive problem to face for building owners, it can also result in the formation of mould within just 24 hours of moisture penetrating a building structure, which is harmful to health and requires extensive remediation work. The unfortunate reality is that many property owners don’t find out until it’s too late.

“With smart technology now embedded into most of our daily lives, we just knew there should be a better solution to this issue. We monitor the health of our bodies, so why shouldn’t we monitor the health of our buildings?

“It really is an exciting new gadget which we believe can help building professionals by providing a cost-effective safety net.”
