Abstract
The invention describes a system for creating potable, 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 for 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 location to restore coastline.
Claims15
A device for coastal restoration comprising:
- a. a bag made of fabric, said bag having a first side and a second side;
- b. said bag having a plurality of pockets, said pockets being created by fastening first side to said second side at a plurality of points;
- and
- c. said bag and said plurality of pockets being adapted such that when aggregate material is place in said bag, said pockets form upper and lower lobes.
A method for coastal restoration comprising:
- a. providing a fabric bag, said bag comprising:
- i. a first side and a second side;
- ii. a plurality of pockets, said pockets being created by fastening first side to said second side at a plurality of points;
- and
- iii. said bag and said plurality of pockets being filled with aggregate material so that said pockets form upper and lower lobes;
- and
- b. placing a plurality of said bags on a shoreline.
A device for coastal restoration comprising:
- a. a plurality of bags made of fabric, each said bag having a first side and a second side;
- b. each said bag having a plurality of pockets, said pockets being bordered by fastening first side to said second side at a plurality of points;
- c. a quantity of aggregate material in each said pocket of each bag so as to form upper and lower lobes;
- d. a mat having a first layer and a second layer, said first and second layers having intermittent points and edges, said first and second layers being attached at intermittent points and at said edges;
- e. said plurality of pocket bags being held in place between said first and second layers of said mat;
- and
- f. said first and second layers being made of grid-like material that is adapted to hold said plurality of bags in place in said mat.
