Abstract
The invention describes a system for creating portable, porous structures for restoring coastline. The invention provides for a bag with multiple longitudinal pockets. The bag is made of porous natural or synthetic mesh material and the pockets are filled with lightweight, porous manufactured aggregate. In a preferred embodiment, the lightweight aggregate used in this invention is produced by thermal fusion of silicate clays in a rotary kiln. In another preferred embodiment, multiple bags are encased in a flexible grid material to form a mat. In another embodiment, the mat can be rolled into a log. The bags, mats, and logs can be placed on shorelines and other locations to restore coastline.
