Frozen construction method for water supply and building/mansion piping renovations! Overwhelming reduction in construction time.

Published in the global scientific journal "Science Advances." Numerous achievements in national government offices and the private sector! Case study materials are also available!

The "freezing method (for buildings)" involves using liquid air (nitrogen) to freeze the water inside pipes, allowing for the replacement or addition of pipe branches and valves with minimal water drainage. The frozen section acts as a stop valve, enabling plumbing work to be carried out without shutting off the water supply to the entire building. A paper on the continuous water freezing method has been published in Science Advances, a globally recognized scientific journal. (We received assistance from Professor Yoshiyasu Muto of Keio University, Faculty of Environmental Information.) ■ The frozen section can temporarily serve as a substitute for a valve, leaving nothing behind in the pipes. ■ It can shorten the time required for water outage work. *For more details, please contact us or download the PDF.
