New York City Subway Meets Fire Code

Challenge

The Metropolitan Transit Authority New York City Transit agency (NYCT) had an expensive problem. Meeting fire code requirements for emergency ventilation of the subway system required closure of openings between tracks. Conventional material solutions such as precast concrete or metallic panels were found to degrade critical radio communications with in the tunnels. Replacement of the communication system was estimated to cost close to $1 billion. NYCT looked to Advantic for an alternative material solution with mechanical performance equivalent to conventional concrete but without the detrimental signal loss.

Solution

Advantic succeeded in meeting the mechanical and combustion requirements utilizing a proprietary cast polymer system developed over a decade of research. Advantic’s cast polymer composites provide the compressive strength of conventional concrete at a weight savings of over 75 percent, while being radio frequency permeable, impermeable to water, and non-corrosive.
