Dam Construction

The Challenge

The client was building four more doors to a dam located in Northern Canada, where temperatures can dip to below -30ºC. The extreme cold can dramatically increase the time it takes for a single slab of concrete to cure. To counteract the cold weather effect, the client built a heated shelter around the slabs so the concrete would not be affected by the outdoor climate. In order to maintain curing progress, the client needed a reliable concrete temperature monitoring solution that would measure both surface and core temperatures of their large slabs simultaneously. 

The Solution

The client chose LumiCon Concrete Sensors for their ruggedized industrial design, industry-leading accuracy, and reliable connectivity. LumiCon Concrete Sensors are built to operate comfortably in the extremely cold conditions of Northern Canada. 

The Result

Using LumiCon, the client was able to effectively control the curing progress of their large concrete slabs despite the harsh weather conditions of the site, all while maintaining regulatory standards and keeping their clients well-informed.

LumiCon provides good data for us to show the client right away that we are following the progress of the concrete closely, and it even allows us to strip the forms and remove the thermal shelters quicker. The system helps us prove that the concrete has adhered to its thermal curve, helping us streamline our project schedule.
