Aqua Barrier  the water inflated dam system is an ideal for creating a dewatered area for pipeline crossings and repair.

Aqua Barrier can be used to fully block both upstream and downstream water and allow pipelines to be driven across smaller water courses without the need to create an earthern bund or sand bags which are unreliable and prone to leaks.  For pipeline repairs in the middle of a wide watercourse then it is possible to fully enclose the works area with 4 or more Aqua-Barriers instead of trying to install sheet piling from a barge. 

Aqua-Barriers are easy to install and quick to fill and most projects will be operational within the first day on site.  They are sturdy and can be re-used many times.

Environmentalists love them because the create little or no disturbance to the environment and they also prevent any fines from being washed from the site, so there is no need for a silt curtain.
