This is our Screed Sensor.

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.

How to install our ScreedSensor

Frequently asked questions

When can I install the sensor?

The sensor shall be installed after the floor has been primed. If the primer is applied on the sensor, it will show incorrect measurements.

How often do I need to scan?

We recommend that you scan once per week. It is not super important that the scanning is performed exactly each seven days. It is however our experience that if drying is not going well, it is often good to have a dry-out curve that is sampled approximately once a week to be able to draw conclusions.

What happens if I do not register temperature?

Nothing really happens, you will still have values from the sensor. However, if there is a problem, the first thing they will ask you is “what was the temperature?”, because temperature influences the moisture content in the screed. So, it is good to know the temperature to be able to explain possible deviations.

What sensor shall I use, 20, 35 or 50?

It is important to place the sensor 30-50% down in the screed (measured from the surface), but never closer than 10 mm to the surface. So, if you have 40 mm screed, the 20-sensor should be used. If you have 50 mm screed, use the 35-sensor. The important thing is to register the final depth (it is not always as you planned 😊). If the screed is different than you planned, we have correction factors applied in the calculations and can compensate for the deviation.

Why do I need to state the type of screed?

Screeds are different! We have performed tests with different screeds and with different thicknesses. Therefore, we can apply correction factors to get the correct values, but we need to know which of the screed sensors you used, what type of screed and how thick the screed is.
