The Maryland House of Delegates’ office building had leaking roof drains and a failing HVAC pipe system. The roof drains were cracked and breached, which allowed water to get into the building during rainfall and snow melt and caused damage. The HVAC system throughout the building was breached, corroded and nonfunctional. The pipes ran throughout the building and were embedded in parts of the original structure that the customer did not want to disturb. While the Lowe Office Building was going through a $9 million remodel to bring the inside infrastructure systems up to date, the municipal property manager felt it was the best time to rehabilitate these failing pipe systems.
Nu Flow successfully cleaned and lined the aged and leaking roof drains with our patented Pull-in-Place structural liner, which covered up all leaks and will prevent future problems from occurring. Nu Flow also successfully cleaned the failing heating and cooling system and applied our patented epoxy coating using our blown-in technology.
The HVAC pipe system now has a protective barrier that will prevent future corrosion from building up. Nu Flow preserved this government building with our innovative, no-dig technology.
Nu Flow was able to effectively rehabilitate the roof drains and HVAC pipe systems without destroying the building and without disrupting the other contractors’ work. Our rehabilitation process also saved the customer time and money and will greatly extend the useful life of these pipe systems. Steve Howe, Nu Flow's Executive Vice President stated “This job is a showpiece for Nu Flow. The customer was very excited about the technology and loved the way we rehabilitated the pipe systems in place,greatly extending their useful life.”
The original storm drains along the fourth floor’s roofs are made of galvanized pipes that range from 3” to 5” in diameter. The entire HVAC heating and cooling pipe system consists of about 1.5 miles of black iron pipes that range from 2.5” to 4” in diameter.
