Until now it's been impossible to know the moisture levels behind a sealing layer without damaging the construction. It has been impossible to know the dry-out status of your newly applied screed without drilling in it. That changes today.
Our Standard Moisture Sensor can measure relative humidity in walls and floors. It is a passive and super thin sensor (like a sticky label), which makes it affordable. The components in the system are: The sensors installed, a scanner used for scanning the sensor values, a mobile phone application connected to the scanner for read out of values and a cloud service where all your installations, sensors and sensor values are stored for future analysis and visualization.
Our Screed Sensor helps you to take control of the dry out process of screed. Before the screed is applied, the Screed Sensor is glued (self-adhesive) to the floor so it ends up approximately in the middle of the screed. No other moments are required. After the screed had been poured out, the floor can be scanned once a week and a dry out curve is created in the cloud service. In the cloud service the time until the dry out has reached the required level can be estimated.
Apart from knowing when the screed is dried out, another advantage is that also deviations from the expected dry out curve will be detected. For instance if the measures on a construction site are not followed, or there is additional moisture added in parts of the building, this will be immediately detected by the site manager and extra drying efforts can be installed to keep the important milestones in the construction schedule.
Our ConcreteSensor is the newest member in our product family. It is the first active sensor, meaning it is battery powered and there is no need for scanning. Its application is to measure humidity and temperature of drying concrete. It measures humidity and temperature on three levels in the concrete, so the dryout can be followed in detail if needed.
The sensor is installed when the concrete is poured out and you can follow the dry-out via our web service. The battery life of the sensor is one year, if you have frequent measurements, otherwise it is longer.
The sensor communicates through a LoRa WAN and in case you have no coverage on your construction site, a local gateway can be added to provide the bridge between the sensors and the network.

Flat roofs are subjected to high loads day in, day out: Thermal influences such as heat, UV radiation and cold, moisture resulting from rain, standing water and building moisture, mechanical stress of the supporting structure from exposure to wind, ice and hail, work performed on superstructures and site inspections of the roof surfaces or technical defects in workmanship inevitably lead to ‘small’ leaks in the roof cladding over time.
The Roof Moisture Sensor is an important component in the roof maintenance activities. If you are building a flat roof for a customer, the built in Roof Moisture Sensors will enable a much higher visibility of the moisture status of the roof and thus a more efficient maintenance.
This will result in earlier detection of moisture leaks, which in turn leads to lower maintenance cost, and better energy preservation (once a flat roof starts leaking, the energy balance changes dramatically).
Our PipeSensor is mainly used for Quality Assurance by our partner in Sweden – Preventum. It is passive as the Standard Sensor and uses the same scanner. The sensor is installed when pipes are repaired, and you want to prove that the repair of the pipe is tight and there is no leakage. Repairing pipes instead of tearing out large parts of the building is a huge cost and environment saver. To learn more about this kind of repairs in Sweden, check out Sluta Riv’s Home Page.
