Multi-year infiltration leak stopped in one hour with Prime Flex 920

A hydrophophic polyurethane grout from Prime Resins was used to stop a leak in a sanitary sewer line that had been flowing at 23 litres per minute for seven years.

One hour and 30 litres of a hydrophobic polyurethane grout is what it took to stop a gushing water infiltration into Kingston, Ontario’s sanitary sewer system. Kingston sits at the mouth of the Cataraqui River where the St. Lawrence River flows out of Lake Ontario. Much of the city sits on limestone bedrock that must be channeled to install water, sewer and service lines. The leaking manhole was located on a sanitary sewer mainline that crosses a swamp, and the manhole was acting as a drain. How major was the problem? The city had a leak in a manhole of a sanitary sewer line where a 25-cm pipe came into the manhole at the bottom of the bench. Water was flowing around a pipe union at the rate of about 23 litres per minute, according to estimates from Utilities Kingston. That translates into some 12 million litres of infiltration a year, and the leak was active for seven or eight years.
