How Sandless inflated instant sand bag work?
Sandless inflated bags work by using a special kind of polymer material that expands when it comes in contact with water or any other liquid. The bags are made up of two layers of fabric, with the inner layer containing the polymer material. When the bag is exposed to water, the polymer absorbs the liquid and swells up, causing the bag to inflate and expand. This allows the bag to be used for a variety of purposes, such as creating a barrier to prevent flooding or to lift heavy objects. The expansion flood bags are reusable and can be easily deflated and stored when not in use.
