In a situation where a pipe is located underneath or within a building, pipe replacement is not an optimal solution, as it causes disruption to ongoing operations. NuFlow has the technology to rehabilitate pipe systems without digging trenches or access points by using their patented NuFlow process.
Project: Restore California State Office Building’s failing rain leaders.
Customer: The State of California, Department of General Services, which serves as business manager for the State of California.
Site: California State Office Buildings 8 and 9 located in Sacramento, CA.
System: Galvanized rain leaders on the exterior decks of the two 17-story buildings. The project included 120 five-foot segments and 120 ten-foot segments of 3” drain pipe. Each pipe extends from a surface drain directly into the concrete structure.
Situation: Both office buildings had corrosion and buildup in the rain leaders, causing the pipes to leak within the concrete that encases the pipes. Traditional repairs would have required the removal and reconstruction of a significant portion of the concrete building to access the pipes. A pipe retrofit from NuFlow was chosen as part of an overall remodel of the building.
Solution: NuFlow saved the customer from the cost and logistics of replacing the system, which would have caused extensive damage to the office buildings. First, NuFlow removed all buildup and corrosion, returning the pipes back to their original diameter. Then NuFlow rehabilitated the pipes with the patented NuFlow process by pulling a seamless structural liner into place through access points on the outside ledge of each floor, greatly extending the pipes’ useful life. The work was performed around the schedule of the state workers to avoid disruption.
Corrosion and leaks are common symptoms of a failing pipe system whether in commercial, industrial, or residential buildings.
Retrofitting pipes without disruption to ongoing operations in the buildings is one of NuFlow’s many advantages.
