Subsurface Flow Control

In major metropolitan areas, mass transit such as rail, bus, and subway systems make up a critical infrastructure involved in recovery support following a major flooding event. Barrier Force™ infrastructure protection barriers have been deployed to protect subsurface mass transit facilities or operations and critical assets in multiple locations around the United States, with a primary focus on switch stations, substations, tunnel entrances, and critical tracks—all of which incur extra flooding risk.

Barrier Force™ infrastructure protection barriers have been successfully deployed in subway entrances, subsurface tunnels, critical power sources, and operation centers, allowing municipalities to mitigate flooding risk and quickly start up mass transit systems after weather events.
