Slide 2 FlexibleRobustReusable Flood Fighting Barriers Slide 3 The Problem $5.3 Billion damage caused by flooding each year in USA $5.3 Billion damage caused by flooding each year in USA An estimated 75% of all flood damage is caused by water less than 3 deep An estimated 75% of all flood damage is caused by water less than 3 deep Single most used protection from this damage is temporary sandbag dikes Single most used protection from this damage is temporary sandbag dikes $158 Million spent on sandbags to protect New Orleans from Katrina $158 Million spent on sandbags to protect New Orleans from Katrina Slide 4 Typical Solution to the flooding issue Currently Currently 300 Sandbag wall 56-5 ton truckloads of sand 700 Manhours 7000 bags Shovels, tools, logistics Redeployment, clean- up and landfill disposal Total Cost $62,550 Sandbags Set-Up Manhours Slide 5 Sandbag barriers can be effective. However the amount of manpower and logistics required to build sandbag barriers is massive, and therefore not typically available in a time of imminent disaster.

Slide 20 Cuts and punctures will not run or rip. Even with a relatively large puncture the leakage rate is low allowing time to respond. Slide 21 In-field repairs are made easily with available materials when necessary. This repair was made with a T shirt.
