Flood Water Bag

Super absorbent flat bags swell up on contact with water to become a solid, heavy barrier to quickly dam and divert floodwater. Stack 26″-long sandbag replacements to create a retaining wall in flood-prone areas when water is coming. Lightweight, compact and easy to handle before activated, unlike standard sandbags which are heavy, messy and labor-intensive. Stack and stagger up to three rows high; build even higher retaining walls by using a pyramid layout. NOTE: Not for use with salt water.
