PVC Keeps Subway Riders Low and Dry

SUBTERRANEAN NEW YORK CITY, N.Y., Feb. 21, 2012 – The Metropolitan Transportation Authority is halfway through a major subway expansion project using a durable PVC membrane to waterproof the system. 

New York City began building subway lines in 1900, and the system, with 800 miles of track and 4 million riders a day up to 140 feet below the street, is one of the world’s largest and busiest.

Water damage from leaks and seepage has been a constant and costly maintenance problem.  The continuous PVC membrane being installed in the expansion project is designed to keep the system dry. 

The bright yellow material is 10 times as thick as a shower curtain, with similar flexibility and waterproofing qualities.  The PVC sheeting is quick to apply, even to moist or wet areas, and can be stretched to insulate uneven substrates.   The membrane is resistant to low temperatures, tearing, and aggressive onslaughts of water, and is easy to repair if necessary. 

Wisko America, Inc., which specializes in waterproofing tunnels, is installing the PVC membrane.  The company has 65 similar projects completed or underway throughout the United States.
