Quick Dam Flood Barrier absorbs, contains and diverts problem flood water. Activate when wet with no sand or tools needed. The inner absorbent turns to gel and creates a barrier that blocks and diverts additional water. Grows to full 3-1/2 inch high in minutes. Can be stacked like a pyramid as needed. Attached smaller wedge prevents barrier from rolling out of position. Compact, lightweight and quick and easy to deploy. No more filling sandbags. Leave in place for months of ongoing protection. Not for use with salt water. Use for flood control, erosion control, ballistic protection, water removers, ballasts and more.
