Off the Wall Products offers plastic water-filled barriers that in the event of an evacuation can be emptied of water and moved quickly, converting two-directional traffic lanes into a single, efficient escape route. Plastic barriers can be moved quickly and easily, whereas concrete barriers require cranes to lift and reposition them. Ease of setup and ready mobility make water-filled barriers a smart highway safety resource. For cities that need to respond to emergency situations quickly, they offer flexibility in traffic control exactly when it's needed.
