Mbz Industrial,

The Sandless Sandbag that absorbs 50 times its dry weight and doesn't allow leakage for up to 90 days after use. Patented technology, based on re-application of medical technologies, allows water quickly in but doesn't allow water seep or quick evaporation unlike burlap, common non biodegrading fiber paper, or clothe. As a 97% biodegradable GREENproduct, once use is complete, the 19" X 21" FloodSax® can be removed full of water for other application, like drought irrigation or other useful hydro applications. 1 lb dry/ 50 lbs wet, FloodSax® will soak-in water like a sponge in only 3 minutes. Great for proactive pre-placementespecially for those with (or hoping to avoid) back/shoulder problems or empowering the elderly, disabled and community who's flooding is imminent but don't have the time, money or access to a sand bag crew to prepare.
