Abstract
A barrier device includes a first containment chamber and a second containment chamber. The first containment chamber is secured to the second containment chamber by a connector. A barrier wall includes a first barrier device having a first containment chamber, a second containment chamber, and a connector. A containment chamber of a second barrier device is positioned between the first containment chamber and the second containment chamber and is positioned in overlying relationship to the connector. A barrier wall is built by positioning a first barrier device, having a first containment chamber, a second containment chamber, and a connector on a support surface. A containment chamber of a second barrier device is positioned between the first containment chamber and the second containment chamber of the first barrier device and overlying the connector.
