Location: New York, New Y ork Situation: The historic cathedral had failing 175-year-old multi-level roof drains that are embedded in the walls, behind two feet of brick work and 100 feet above street level. There are more than 50 drains in the system and some pipes range from 30 feet to more than 100 feet in length. Solution: Nu Flow’s Pull-in-Place liner was able to succeed where a previous relining job had failed. Nu Flow’s trenchless technology for in-building pipe rehabilitation preserved the historic structure and prevented further destruction to the building. Where life interacts with infrastructure.
