It is a sand weighted bag, specifically developed for coastal protection. These cumulative weights create the resistance of the dike in the event of flooding hazards.
BIGBUMP® can also be used to ballast the BUMPBLADES®, or can be used as reinforcement for existing cofferdams.
The BIGBUMP® can be filled with sand on site with a hopper hopper. And can be set up in the space of a tide.
