Tour Oklahoma Capitol With Pipe Lining Technology Answer
The Oklahoma State Capitol sits on more than 100 acres in NE Oklahoma City.
The capitol’s cast iron roof drain was leaking during heavy rains. The roof drain was eight-inch vertical line, approximately 100 feet in length and included reinstatements of two condensate branch lines. Replacement was not an option due to the disruption to occupied office spaces where the branch lines were located.
Using Flow-Liner technology, a Flow-Liner Certified Installer prepared and installed the Flow-Liner Cured-In-Place Pipe Lining System.
The roof drain line was successfully lined and branch lines were reinstated without excavation or disruption of the occupied office spaces at the capitol building.
