How To Use Flood Blok Bags

The Dry bags weigh less than 2 lbs each and are easy to use. Simply unroll or unfold each bag and lay them end to end and stack as high as needed to help prevent water damage to any area.  When water comes in contact the bags, they will swell to approx 8-10" high and fill to hold up to 40 lbs of water.  


After water has receded, the bags will deflate automatically.  Once dry, Flood Blok bags can be folded or rolled and stored in a cool, dry place for use again.
