ABSTRACT:
Floating wetland structures of the invention are generally formed from one or more floatation panels made of a plurality of polymeric foam particles arranged in a piled laminate structure. The foam particles are arranged within the piled laminate structure so as to define void pathways between at least a portion of said foam particles. The void pathways within the piled laminate structure are of sufficient size and quantity to allow rainwater to flow through and of such an orientation to allow for the roots of vegetation to easily penetrate the structure.
