    Santo Domingo, Dominican Republic

    February 13, 2011
    Xypex was used to waterproof the concrete in the initial construction phase of the Santo Domingo Metro. Over 100,000 lbs (45,000 kg) of Xypex Admix C-1000 NF was installed in the concrete required by 15 km of tunnel construction. 

    Based on the successful results of this first application, Xypex Admix C-1000NF and its proprietary crystalline technology has again been specified for the waterproofing and protection of the tunneling in the second line of the metro – estimated at 13 km, and a completion date of mid 2012. The Santo Domingo Metro, part of a National Master Plan to improve transportation and expand infrastructure, is the first subway system in the Dominican Republic and the second in the Caribbean and was prompted by the need to reduce the continually rising road traffic congestion and air pollution in the city.
