The Ultra-Aqua Bag is a “sandless sandbag” that weighs less than one pound in its unactivated state. But submerge it in fresh water and within minutes you have 30-40 pounds of flood-stopping force.

No more panicked/fruitless searches for sand. No more back-breaking work of filling a bunch of bags. Ultra-Aqua Bags can be activated by submerging in water or by putting them in place and saturating them with a hose.
