For a four-story residential timber building that combines traditional reinforced concrete materials with CLT panels, we designed a system to provide complete protection against elevated moisture and water leaks. Wood is used not only as the load-bearing structure but also as a visible interior material for selected partition walls on all above-ground floors.

Sustainability in Construction
The building uses a total of 1,600 m³ of wood, reducing the amount of concrete needed by up to half compared to standard construction methods. SENZOMATIC contributes to the sustainability of the building by significantly extending its lifespan through early detection of emerging moisture or small to large water leaks.

Moisture Protection Design
We divided the building’s protection into two parts—monitoring water leakage from the green roof and monitoring the moisture levels in the wooden structure within the residential units. Thanks to the standardized layout, each unit could be equipped with an identical set of sensors placed in the same locations.
On the ground floor, we installed MHT sensors under the showers to monitor wood moisture and temperature, and also placed them in the utility room under the floor where the washing machine and dryer are located. We didn’t overlook the door frames leading to the terrace, where condensation and water infiltration into the wood often occur due to temperature differences between the interior and exterior.
In the upper-floor apartments, the same sensors were installed, with the only difference being their placement in the balcony door frame instead of the sliding terrace door.

Retention Tank Challenges
The residence’s flat green roof is designed to capture rainwater in storage and retention tanks with a total volume of 135,000 liters. This water is then used to irrigate greenery in shared areas.
Despite their many advantages, green roofs pose a higher risk of water leakage into the building due to microcracks in the insulation, clogged drainage systems, or faulty distribution joints. To ensure proper monitoring of this area, we decided to use special HT-R sensors, which detect increased moisture and water presence and accurately localize the source of the problem.

Installation included:

• 457× MHT sensors
• 160× HT-R sensors
• 38× central units
