The New York Department of Transportation, after rigorous testing and evaluation, has approved Formadrain’s design-engineered, no VOC pipelining solution as a FEP (Functionally Equivalent Product) for use by NYDOT.
The decision comes after a Formadrain product demonstration was done in the NYDOT warehouse parking lot in Albany last August. The demo showed NYDOT engineers and officials every aspect of the Formadrain system from wetout to cure and final video right on the spot and above ground.
The 12″ diameter pipe of corrugated, galvanized steel used in the demonstration was made to simulate numerous difficult pipelining situations which included:
1. a section with a two-foot gap,
2. another section deformed out of round by 20%,
3. a number of punctures in the pipe, and
4. an added section of Sonotube for mechanical testing that also stood for a diameter transition.
NYDOT staff watched as the Formadrain fiberglass liner was wetted out, wrapped around the proprietary Formadrain mandrel and winched into place as in an actual job repair. The liner was then inflated and fully cured by steam pressure after only 50 minutes.
After the liner cooled, a final video of the pipe repair was made and then a Sonotube cross section of the liner and pipe was cut off for testing. NYDOT engineers then took their observations and the demonstration materials to review to make their decision.
The Formadrain® liner passed with flying colors.
If you are looking for a no-dig, trenchless pipelining system, Formadrain is a system you need to investigate. Watch a video of Formadrain in action.
