A hessian bag containing water-absorbent non-hazardous gel. These flood bags provide the same end result as regular sandbags, but with the added benefit of being flat and lightweight for easy storage, transportation and distribution. Designed to be deployed in advance of flooding, 25 bags stacked per regular doorway is recommended. Can be reused or disposed of safely.
Each bag starts at 60 x 35 x 1cm, weighing approximately 200g. Once submerged in water for 4-5 minutes, the bag expands as much as 60 x 35 x 10cm and weighs approximately 15kg.
