Sectional interlocking sandbags

Image Number 2 for United States Patent #6428240.

A length of material, such as woven polyethylene, woven polypropylene, burlap, or other woven material, divided into a series of two or more substantially equal sized sections. Every other section is filled with sand, or other material. When the length of material is put in place, each row alternating a filled section and an unfilled section, a very secure, interlocking, substantially water-tight structure is formed which is much more effective in preventing the flow of water, mud or silt. Because each section is substantially square, the sections can be stacked in a parallel or transverse direction, to effect a wider and stronger structure which is substantially impervious to the flow of water, mud or silt.
