Presentation Description

75% of the $5. 3 BILLION in annual flood damage is from floodwaters less than 3' deep. The FLOODWALLS system can be deployed by volunteers and emergency response personnel in less than 2 minutes per foot. Sandbags take over 50 times longer.

The Problem : 

The Problem An estimated 75% of all flood damage is caused by water less than 3 feet deep

The Problem : 

The Problem An estimated 75% of all flood damage is caused by water less than 3 feet deep Single most used protection from this damage is temporary sandbag dikes

The Problem : 

The Problem An estimated 75% of all flood damage is caused by water less than 3 feet deep Single most used protection from this damage is temporary sandbag dikes $158 Million spent on sandbags to protect New Orleans from Katrina

Typical Solution to the flooding issue : 

Typical Solution to the flooding issue Currently 300 foot Sandbag Wall 56 - 5 ton truck loads of sand 700 Man hours 7000 bags Shovels, tools, logistics Disassembly clean-up and landfill disposal TOTAL COST $62,550 Total Cost $62,550 Sandbags Set-Up Manhours

An Alternative Solution Floodwalls: 

An Alternative Solution Floodwalls 300’ Floodwalls Barrier 20 -A5 Units (148 lbs. ea) 14 Manhours (5+fill) Firehose and Water 1 Pickup Truck 100% Reusable (No Environmental issues) Total Cost - $36,100

Floodwalls - Technical: 

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

Standard Units: 

Standard Units 4 Standard Shapes Free standing - 3 Wall supported - 1 4 Standard Lengths - 2, 3, 4, & 5 meters Protective heights - up to 5’6”+ Residential units - 18”- 24” depth, 3’- 20’ length

Cost Analysis: 

Cost Analysis Sandbags 56-5 ton truckloads of sand 700 Man-hours 7000 Sandbags Shovels, Tools, Logistics Disassembly, clean-up, disposal One Use Cost $62,550 10 Use Cost $625,500

Cost Analysis: 

Cost Analysis FloodWalls 18 A5 Units 14 Man-hours Fire hose and Truck 1 Pickup Truck 1st Year Cost = $36,100 Per cost use =$6,300 @ 10 uses Ten Year Cost = $63,100
