Abstract
A portable and collapsible barrier that is lightweight and can be easily transported and erected. The barrier includes a base, a top and an enclosed volume such as a diaphragm that can be expanded with a medium such as a gas or liquid to a desired shape. The expanded volume will act as a barrier. When a series of expanded barriers are connected, they will form a wall that can contain bulk materials or liquids.
