Patent attributes
A fluid-fillable barrier which includes a flexible, tubular, impermeable membrane and at least two internal tension members. The membrane has opposite ends, a middle, fluid-fillable section, an upper attachment area, and a lower attachment area. The tension members secure between, and extend from, the upper attachment area to the lower attachment area. The tension members have a length which is less than one-half the perimeter of the membrane, the length and perimeter being measured at a common cross-section, taken perpendicular to a longitudinal axis of the membrane. One of the tension members is longer than the other, so that it is in a relaxed, limp state under normal operating conditions. The tension members are thermally bonded to, and sewn with a double sew line to, the attachment areas. The barrier further includes lifting loops at each end, connection cleats on the sides and ends, and venting/drainage standpipes.
