A portable barrier wall used for preventing the passage of people, vehicles, projectiles, blast debris, liquids, wind or waves through the wall. The wall is constructed of one or more x-shaped freestanding support structures arranged in parallel orientation to form a frame for holding retaining members that attach to the support structures. The retaining members form U-shaped containment structures within each segment of the wall. Fill material is added to the containment structures which are then sealed. Connecting means attach the two support structures together to prevent movement. Wall used to contain liquids may additionally include a liquid impervious layer that is placed external to the retaining member on the side of the barrier wall that will be in contact with liquid and the layer is anchored under the feet of one of the support structures. The wall may additionally hold absorptive or adsorptive materials to contain spills and contaminants.
