Extruded hollow aluminum planks with interlocking mating surfaces are stacked on top of the base plank. Each plank weighs approximately five pounds per foot, so two workers can easily handle any IFCW™ plank (max. 20').

Patented aluminum planks seal with hard rubber gaskets and become side-thrust resistant with a unique tongue and groove design. The planks fill with water as flood height increases, creating further stability and integrity.
