Mass concrete pours: hydration heat tracked at every depth
Thermalpas sensors and a temperature/humidity logger follow the 28-day hydration curve after large pours.

The problem
When you pour a massive concrete foundation or column, the chemical reaction inside generates 70°C+ of heat. Pour it too fast or the wrong way and the inside stays hot while the outside is already cool, the concrete cracks internally, and the structure fails its strength test a month later — too late to fix. Conventional embedded thermocouples interfere with rebar and are one-shot consumables.
What was installed
High-temperature Thermalpas sensors were embedded at depth in the pour and strapped to the rebar cage alongside a waterproof temperature/humidity logger. The temperature curve at each depth was tracked in real time, so the site engineer could see every depth zone of every pour and intervene if anything was heading the wrong way. A concrete strength-development forecast was produced for contractors and inspectors.
The outcome
Contractors using the system report eliminating pour-related cracking on their large projects. The data also feeds project documentation, giving building inspectors an auditable record of the curing process. On one high-speed rail pier project, early strength confirmation shortened formwork waiting by three weeks — about $500K in construction time per pier.
