2 FlexibleRobustReusable Flood Fighting Barriers

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

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

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.

6 An Alternative Solution – FloodWalls 300 Barrier 300 Barrier 19-A5 Units (154# ea) 19-A5 Units (154# ea) 14 Man hours (5+fill) 14 Man hours (5+fill) Fire hose and Water Fire hose and Water 100% Reusable – (No Environmental issues) 100% Reusable – (No Environmental issues) Total Cost - $39,080 Total Cost - $39, – A5 Units 14 Man Hours Fire Hose and water Transportation REUSABLE 20 Year Life

10 Floodwalls - Technical 3mm thick 3mm thick PES fabric – (Ripstop) PES fabric – (Ripstop) Impregnated & coated 2 sides Impregnated & coated 2 sides EPDM compound EPDM compound All joints & seams vulcanized (no glue) All joints & seams vulcanized (no glue) Heat cured oxygen free atmosphere Heat cured oxygen free atmosphere Pressure tested twice – before & after fill coupling installation Pressure tested twice – before & after fill coupling installation

11 Standard Units 4 Standard Shapes 4 Standard Shapes –Free standing – 3 –Wall supported Standard Lengths – 2, 3, 4, & 5 meters 4 Standard Lengths – 2, 3, 4, & 5 meters Protective heights – up to 56+ Protective heights – up to 56+ An optional custom length Apron can be ordered to drape over and protect a levee from erosion An optional custom length Apron can be ordered to drape over and protect a levee from erosion

13 An A Type unit delivered from storage

14 Unrolled A Type unit

15 2 - A Type units in position for filling

16 ¼ Turn Fill / Vent Cap

17 Fill Nearing Completion (10-15 minutes)

18 Completion Second Unit Fill

19 What if a unit gets punctured?

20 Cuts and punctures will not run or rip. Even with a relatively large puncture the leakage rate is low allowing time to respond.

21 In-field repairs are made easily with available materials when necessary. This repair was made with a T shirt.

22 Floodwalls units in place for testing at USACE - ERDC

23 USACE ERDC

24 Phase #2 Before testing Under Load 30% over max level

25 Design Max Depth = 32 Test Depth 42.5

26 USACE ERDC Test Result Comparison 80 ft. Barrier FloodWalls Sandbags Total Man Minutes Leakage Total Man Minutes Leakage Manhours per foot gpm/foot Manhours per foot gpm/foot

27 Cost Analysis 300 Sandbag Barrier 32 high Sandbags Sandbags –56-5 ton truckloads of sand –700 Man-hours –7000 Sandbags –Shovels, Tools, Logistics –Disassembly, clean-up, disposal One Use Cost – One Use Cost – –$62, Use Cost – 10 Use Cost – –$625,500

28 Cost Analysis 300 Floodwall Barrier 32 high FloodWalls FloodWalls –19 A5 Units –14 Man-hours –Transportation –Fire hose & Water 1 st Year Cost = $40,000 or Less 1 st Year Cost = $40,000 or Less Reusable for 20+ years with minimum additional cost Reusable for 20+ years with minimum additional cost

29 Floodwalls Strengths Field Experience 30 years Field Tested Experience Technicians Technicians USACE Testing Patented Design Design Interior Baffles Proprietary Materials Materials EU Patent US Patent Applied Applied Custom Design Design Application Cost Cost Lower Cost than Sandbags Reusable 20 year shelf life
