When is the concrete slab dry enough to start the flooring project? Will we stay on schedule?

To eliminate guessing, the patented eGate ePredict™ tool uses job site IoT sensors and cloud algorithms to provide continuous forecasting of concrete drying dates. Based on the forecast, the job site management can take actions to control the site conditions – for faster drying time.

Features

• IoT RH+T sensors for monitoring both concrete (ASTM 2170 method) and the ambient air
• Cloud-based data, reports, real-time dashboard, access anywhere, mobile and desktop
• First drying forecast available after 14 days of pouring the concrete
• Continuously updates the forecasted date vs. the target date for the desired RH% level in concrete
• Alerts users when the process is behind schedule
• Simultaneous monitoring of multiple job site locations

Benefits

• Use the real-time data to optimize job site conditions early enough to meet the project schedule
• Use the forecasting to trigger actions; add air heaters or dryers on site, control ventilation, HVAC, etc. actions
• With remote data, eliminate the need for onsite visits
• Share the forecasted status, alerts, and reports with the project team using the cloud-based dashboard, mobile, or desktop

High precision sensor technology

• eGate NSENS RH sensor technology delivers the highest available sensor accuracy and reliability.
• ASTM 2170 standard requires concrete RH sensors to meet +/-2RH accuracy. eGate NSENS is specified to meet +/0.8RH accuracy within the 90…100%RH range.

eGate Advantage

Unlike other concrete measurement sensors, that are using cables or Bluetooth for data connection, eGate sensors are directly connected to the cloud as true wireless IoT devices (LoraWAN). This enables real-time data streaming and remote monitoring without any repeat manual measurement tasks on the job site. The continuous data stream also makes it possible to calculate the forecasted drying date.

Before, it Was All Guessing with Manual Tools

The industry best practice has been to let the concrete dry at least for 28 days per inch
of the slab, to reach the desired RH value of 75-85%RH for floor installation. This rule of thumb assumes optimum indoor drying conditions, under 50% relative humidity and above 65°F air temperature. But at the job site, conditions are, of course, changing every day. Therefore, the significant advantage of using ePredict™ is therefore to have all this changing environmental data updating the forecast continuously.

Data for Action!

ePredict™ adds new valuable data points to the construction project manager’s tool kit: the speed of concrete drying right now and the estimated date when the target RH value will be reached. With this data and alerts, it’s possible to act and impact the job site conditions – before it’s too late.
