A barrier includes a main body, a first edge region, and a second edge region. The first edge region can include a first bulging element, and the second edge region can include a second bulging element. The first and second edge regions can be on opposite sides of the barrier and can extend substantially parallel to each other. The main body of the barrier can include one or more regions of increased thickness. The region(s) of increased thickness can be in an intermediate location between the first bulging element and the second bulging element. The region(s) of increased thickness can be spaced from the first edge region and the second edge region such that the region(s) of increased thickness do not contact the first bulging element or the second bulging element. The main body, the first bulging element, and the second bulging element can be configured to be rolled. |
