PRODUCTIVITY Using sand bags, it takes about 760 man-hours to build a 300 feet long wall, while on the other hand only 14 man-hours are needed to build a 300 feet long wall with our WATERWALLS. Approximately 300 tons of sand and 7000 sand bags (about 90 pounds of sand per bag) would be required as compared to only 20 of our WATERWALLS.
ENVIRONMENT No special preparation is required with our WATERWALLS. They eliminate the problem of wet sand, gravel or soil disposal. There is no negative impact on the area where the WATERWALLS have been used.
LOGISTICS ADVANTAGE Our WATERWALLS are easy to handle. It takes only two people to install a WATERWALL. They are easily stored and are reusable. They can be filled with river water using the pump from a fire truck. Typical fill time per bag is approximately 15 minutes. |
