Sandless FloodBag Kit. Sandless Water absorbent
Cost-effective self-filling Hessian bags filled with super-absorbent polymer. Each bag weighs around 600g empty, but in contact with water quickly expands to over 20kg, and forms a more effective barrier to water penetration than conventional sandbags. Compact to store and transport, simple to deploy, and with a shelf-life of 5-10 years, they are a realistically priced emergency flood response system. Not for use with salt water.
