  • Restricting Chloride Penetration of a Concrete Breakwater

    Ensenada, Mexico

    June 27, 2010
    More than 25,000 lbs. of Xypex Concentrate was used to protect the concrete breakwater at Sempra Energy's Energia Costa Azul LNG Receiving Terminal 14 miles north of Ensenada, Baja California. Xypex Crystalline Technology was chosen for two primary reasons: because of its proven effectiveness in restricting chloride penetration; and, because Xypex penetrates deep into the concrete to become an integral part of the breakwater structure, the subsequent maintenance requirements are minimal.

    This breakwater is the first new LNG project on North America's west coast and will have the capacity to import up to one billion cubic feet of natural gas per day. The breakwater is 1300 metres long and integrates two different sizes of concrete caisson each weighing more than 90,000 tons and designed to provide protection against a one in 1,000 year wave.
