Abstract: An apparatus includes a floor having an impermeable material, where the floor has multiple edge portions and each edge portion corresponds to an edge of the floor. The apparatus also includes multiple wall sections configured to form multiple free-standing walls around a perimeter of the floor, where each wall corresponds to one of the edge portions. The apparatus further includes multiple brackets, where each bracket is configured to fit over an associated one of the walls after the corresponding edge portion of the floor is draped over the associated wall. Each bracket is configured to fit against sides of the associated wall so as to hold the corresponding edge portion in place. Each bracket includes (i) first and second plates disposed on opposite sides of the associated wall and (ii) one or more bars extending over a top surface of the associated wall and connecting the first and second plates.

Abstract: An apparatus includes a containment structure having a floor and one or more free-standing flexible walls extending along an outer perimeter of the floor and surrounding a central portion of the floor. The floor includes one or more pieces of fabric, and each free-standing flexible wall includes one or more pieces of shape memory material and extending above the floor. The one or more pieces of shape memory material are attached to the one or more pieces of fabric via a liquid-impervious material applied to the one or more pieces of fabric along the outer perimeter of the floor. The liquid-impervious material is located on the one or more pieces of fabric and the one or more pieces of shape memory material such that the floor and the one or more free-standing flexible walls are liquid-impervious and define a space configured to retain liquid in the containment structure.

Abstract: A method includes wrapping one or more pieces of fabric around at least one piece of shape memory material. The method also includes attaching outer edges of the one or more pieces of fabric to other portions of the one or more pieces of fabric. The method further includes depositing liquid-impervious material onto the one or more pieces of fabric to form free-standing flexible walls and a floor of a containment structure. The floor is formed seamlessly with the walls. The wrapping could include attaching a bottom of the at least one piece of shape memory material to the one or more pieces of fabric at locations spaced apart from the outer edges of the one or more pieces of fabric. The wrapping could also include attaching sides of the at least one piece of shape memory material to the one or more pieces of fabric.

Abstract: A method includes placing at least one mold along outer edges of one or more first pieces of fabric. The method also includes forming free-standing flexible walls and a floor of a containment structure by depositing liquid-impervious material onto the at least one mold and the one or more first pieces of fabric. The floor is formed seamlessly with the walls. The method further includes forming flexible supports by depositing liquid-impervious material onto multiple second pieces of fabric connecting the floor and the flexible walls.
