Flood-preventing bag is made of "Super absorbant polymer". It is packed in gunny sack of poly-weave bag. This synthetic material is non-toric, tastless, not melt into the water and hard to burn. When contact with water, it can expand very quickly to reach about 400 times of the original volume and increased in weight after 2-3 minuts. Thus the water-stopping bag can achieve the purpose of flood-prevention, rescue emergency and block loopholes.

The flood-preventing bag is light in weight, easy to store and convenience to transport. It can be also used to build military bunker. We can supply different sizes of flood-preventing bags.
