J-Track, LLC 2 3 J-Track, LLC J-Track LLC is the commuter’s equivalent of a masked superhero – frequently unseen, but instrumental in saving the day. As a company that specializes in end-to- end track and transit system construction services, J-Track is frequently the unsung hero in circumstances where flooding and water leaks threaten to grind to a halt the daily subway commute in metropolitan cities like New York and Washington, D.C. 4 Written by Gina Stephens his was the case recently when J-Track was hired to ensure that the Red Line of the Washington Metro rail Trapid transit system would be better able to cope with torrential rains and flooding, as well as frequent water seepage. Flooding has been a perennial problem for the Red Line – last summer, flash floods caused commuter chaos, resulting in passengers having to wade through shin-high water, and one of the Red Line stations, Cleveland Park, was being bypassed because the water inundation was so severe that water was cas- cading down the escalators, causing them to short out. Storms are a major cause of the Washington Metro flooding, but the geographic placement of some of the Red Line stations, placed at the bottom of a hill, create a structural weakness when it comes to water seepage. To address this issue in a more permanent fashion, Washing- ton Metropolitan Area Transit Authority (WMATA) hired J-Track to commence work in July 2017 on a pilot project that would use one of the company’s proprietary techniques, employ- ing “curtain grouting” to add a waterproof membrane to the exterior of the Red Line’s tunnel walls using a polymer-based material that J-Track created. “Since this tunnel segment was constructed, Metro has fought a battle against Mother Nature, and Mother Nature has always had the upper hand. Just as we have addressed the root causes of track infrastructure problems and railcar reliability issues, I want to address the water infiltration problem head on and find a sustainable solution. Our Red Line riders deserve nothing chocolate syrup cascades down an ice cream sundae). less,” said Washington Metro General Manager and CEO Paul J.
