AquaDam® is a unique, patented idea that uses water-filled tubes to create barriers and control water to prevent flooding. AquaDam® was originally designed as a method for blocking streams for pipeline crossings. Using AquaDams to complete pipeline crossings is one of the most environmentally effective methods in use and is ideal for crossings involving large diameter pipelines.
AquaDams are also ideal for flood control and have been used effectively to prevent flooding and form aqua barriers for several communities. Furthermore, AquaDams can be used for temporary water storage in areas stricken by drought or where wildfires are expected.
On-site requirements for AquaDam® installation include a portable pump and the usually abundant local water supply. This makes AquaDam® ideal for water control projects such as stream or lake bed construction diversions, aqua barriers, cofferdams, and environmental pollution confinement and silt control.
AquaDam® provides fast, effective relief for tougher applications such as mudslides, hazardous waste control and flooding. AquaDam® is also an ideal choice for preventing the overtopping of levees, which is the number one cause of levee failure. Layfield's AquaDam® acts as a temporary portable cofferdam that can be reused. Cofferdams of this type are stretched across the site, then inflated with water from the prospected dry area to create a dry working environment. Cofferdams are excellent for creating watertight enclosures for repairs and exposing the bottom of a body of water.
AquaDams combines three or more polyethylene or woven geo-tech tubes and any available water supply. The two 'inner' tubes, contained by an outer 'master' tube, are pumped full of water simultaneously. Counter friction between the master and inner tubes results in a stable, non-rolling 'wall' or aqua barrier of contained water, which adjusts automatically to bottom terrain as the AquaDam® deploys. Within minutes, an impervious wall of solid AquaDams is formed.
A few of the more common uses include:
Water diversions and aqua barriers during pipeline installation in and around rivers or standing water.
Water containment during repairs on bridges, sewage systems and power plants.
Easy, rapidly deployed to form an aqua barrier and flood control.
Erosion control through diversion or containment of flowing water.
Temporary reservoirs for water storage.
Temporary cofferdams for containment of spilled materials.
Silt containment and sediment collection.
