The Patriot M50 Passive Barrier Wall offers cost-effective design and minimal installation time plus vehicle-arresting strength. Made by Patriot Barrier Systems of Waldorf, Maryland, the wall does not require a full-length concrete foundation, so it won’t interfere with underground infrastructure. Custom finishes include stamped or tinted concrete, and finishes that mimic granite, fieldstone, slate, brick, and wood. Three distinct designs (barrier wall, knee wall, and cable-only) share a hidden, vehicle-arresting cable system comprised of two wire ropes, each running through a 41⁄2-inch conduit. The cables are attached to reinforced concrete posts at each end, each with a 10-foot reinforced concrete foundation.
