Emergency waterproofing, flood measures, typhoon measures, and guerrilla heavy rain... Soak in water for rapid expansion! A new type of sandbag that expands with water!!
Compared to some time ago, there have been many occurrences of water damage due to localized heavy rains and the successive landfalls of typhoons. To prevent water intrusion, sandbags are necessary, but we hear that sand-filled bags are heavy and difficult to store. Mizupita is a sandbag filled with a polymer absorbent that expands with water. It swells to 20 times its volume in just a few minutes when soaked in water! *The H-type for seawater and freshwater expands in about 3 minutes in seawater and about 1 minute in freshwater.

basic information
★You can use it just by inflating it with water before use! ★It takes up little space and is lightweight! The N type and H type take up little space at 500×400×3mm before inflation, and they are also lightweight at 0.14kg, making them easy to handle. ★Even when inflated with water, it is lightweight at 10kg! It is lighter and easier to carry than sand-filled bags (25kg). ★With a string, you can connect multiple water pitas! Water pitas can be used with both fresh water and seawater. *For use with seawater, please use the seawater/fresh water type. With the adoption of new materials, the weather resistance has improved compared to the conventional white fabric! The water absorption speed remains the same, and it is less likely to become slippery, allowing it to last about three times longer than before.
