The Washington Metropolitan Area Transit Authority (WMATA) is expanding a pilot of a new waterproofing membrane along the Red Line.
The agency will continue installing the material along another 4,000-foot section of inbound track between the Medical Center and Grosvenor stations. The material is injected into the tunnel walls to form a waterproof membrane on the exterior of tunnel walls.
