A gabion sack made from HDPE rope net. Non-corrosive rope in braided twine and woven into a sack in pillow, cylindrical, or conical shape that can carry 2 to 8 tons of load. Small stones can be filled off-site, trucked to site, and placed in moving water, all in the sack.

 Applications include scour protection, underwater ballast, river training, and revetment. The sack is flexible, conforms well to uneven bed profiles, is highly porous, and resists aggressive and abrasive environments. It can be customized with a lifting loop for easy handling.
