Bulwark structure and method

A method of forming a bund system for the retention of solid, liquid or pourable material in an enclosed area;

• the method including the steps of:
• (a) erecting a plurality of double rows of spaced apart parallel panels to form a plurality of retaining structures, each of the plurality of retaining structures being disposable in a substantially vertical position with respect to a ground surface;
• the respective panels in each of the plurality of retaining structures comprising retaining elements connected to and extending from inward facing surfaces of the respective panels partially across the space between the respective panels, the retaining elements of each retaining structure being disposed with respect to the respective panels of the retaining structure such that, when the panels are disposed in the substantially vertical position with respect to the ground surface, the retaining elements are disposed in a horizontal position with respect to the ground surface;
• the retaining elements of the respective panels being provided at their outer ends with projecting structures forming soil anchors which are constructed and arranged to engage with backfill material to maintain the respective panels in spaced apart position and to effectively lock the respective panels in a substantially vertical position with respect to the ground surface;
• (b) backfilling the space between each of the double rows of spaced apart panels with backfill material to effectively lock the panels in a substantially vertical position with respect to the ground surface, and
• (c) sealing horizontal and vertical spaces within the bund system with sealing elements to prevent the solid, liquid or pourable material from leaving the enclosed area.
