Solution implemented

Cryogenic plugs create a temporary valve, making work easier and more fluid, quicker to install, and a safe, proven technique.

The cryogenic plug in the video was held for over an hour at -196°C. After the cryogenic plug was thawed, the concrete lining remained intact, with no signs of concrete delamination, and the three-layer polyethylene or polypropylene lining remained intact.
