This Quick Dam Flood Bag 6-Pack helps protect your property with minimal effort. When wet, the inner absorbent turns into gel to form a barrier that blocks and diverts water. Growing to 3.5 inches in minutes, these sandless sandbags are lightweight and easy to deploy, providing a reliable flood solution that can last for months. Ideal for flood control, erosion control, ballistic protection, and more.  Not for use with salt water.
