There are three primary types of Aqua-Barrier® Installations. The following descriptions of the various types of Aqua-Barrier® installations are simplified and are only meant to give a general overview of the installation process. More detailed installation information should be provided by a trained HSI Services representative on all Aqua-Barrier® installations.
During all Aqua-Barrier® installations the barriers can tractor or rotate toward the side that possesses less water depth. The maximum amount of movement is ½ of the properly inflated barrier height. For example, a 6 foot high barrier can adjust as much as 3 feet. This is a natural adjustment needed for the internal baffle to engage.
The same adjustment behavior can occur if a slope or grade exists from one side of the barrier to the other. Barriers which are not inflated to their proper height can tractor toward the dewatered area more than ½ of the recommended inflated height.
Dry Surface Installation:
The location where the barriers are to be installed has no water present. The barriers are simply unrolled and inflated. This style of installation is generally used in anticipation of flood waters.
Static Water Installation:
Non-moving water is present at installation location. The barriers are buoyant and float on the surface of the water. The barriers are placed at the water’s edge, unrolled on the water’s surface and then floated into position. Read more information about Standing Water Installation.
Dynamic Water Installation:
Dynamic or moving water is present at the installation location. Barriers are positioned properly by controlling the ends of the unit with hydraulic equipment (i.e. track hoe, crane) and/or anchoring at least one end of the barrier to the shoreline.
