VAKKA are sensors that wirelessly monitors the environmental conditions within the concrete as it hardens. The patent-pending environmental chamber is unique to the VAKKA system and allows for faster and more accurate readings. It quickly equalizes the surrounding environment allowing precise measurements to be recorded within minutes of pouring your concrete.
The free mobile app and cloud service empowers the user’s team to make faster and more confident decisions. The data can be downloaded to the app at any time when a connected device is within the 3-4 m range of the sensor and is instantly uploaded to the cloud where it is shared with the team. The app estimates the compressive strength by using the user defined maturity curve and allows instant access to the temperature and relative humidity readings, plotting data, and reports.
With the VAKKA sensors, the traditional method of braking cylinders is improved in accuracy and project cost savings by reflecting better the concrete strength gain in real-time. On the other hand, by knowing the up-to-date level of relative humidity of in-place concrete, the timing in which floor coverings are installed, such as resilient flooring, wood, epoxy or polymer-based coatings, can be optimized.
