Absorbent bag for building temporary barriers

Abstract

A bag for creating temporary water barriers. The bag may include an outer casing and a liquid absorbing polymer within the casing. To use the bag, the bag may be soaked in water and the liquid absorbing polymer may absorb the water. The bags may then expand and may be stacked to create the barrier.

What is claimed is: 
     
         1 . A temporary barrier building bag comprising:
 a outer casing; and   a liquid absorbing polymer within the sealed outer casing.   
     
     
         2 . The temporary barrier building bag of  claim 1 , further comprising a vacuum tight seal surrounding the outer casing. 
     
     
         3 . The temporary barrier building bag of  claim 1 , wherein the liquid absorbing polymer is a cross-linked polymer. 
     
     
         4 . The temporary barrier building bag of  claim 1 , wherein the bag comprises a non-expanded state and an expanded state. 
     
     
         5 . The temporary barrier building bag of  claim 4 , wherein the expanded state comprises a mixture of the liquid absorbing polymer and a liquid. 
     
     
         6 . The temporary barrier building bag of  claim 5 , wherein the liquid is water. 
     
     
         7 . A method of creating a temporary barrier comprising:
 providing a bag comprising: a outer casing; and a liquid absorbing polymer within the outer casing;   soaking the bag in a liquid, wherein the liquid absorbing polymer absorbs the liquid and expanding the bag;   stacking the bag to create a barrier; and   repeating the above steps until the temporary barrier is complete.   
     
     
         8 . The method of  claim 7 , wherein the bag further comprises a vacuum seal surrounding the outer casing. 
     
     
         9 . The method of  claim 8 , further comprising the step of removing the vacuum seal prior to soaking the bag in liquid.
