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.
