How does
Aqua-Barrier® work?
Aqua-Barrier® requires surface friction to stabilize when exposed to uneven hydrostatic pressures.
The internal restraint baffle(s) lock into place when the barrier is exposed to greater hydrostatic pressure on one side.
Barrier height helps determine the freeboard clearance required for adequate water management. Freeboard is the amount of inflated barrier above water level. A minimum of 25% freeboard is required in all Aqua-Barrier® installations.

Successful water management requires stabilization
Aqua-Barrier® redefines successful water management with its groundbreaking internal baffle system, designed to prevent rolling and ensure unmatched stability. Unlike other inflatable barriers that rely on external components for steadiness, our unique single tube design inherently eliminates the need for such additions, offering a sleeker, more efficient solution.


Divert water effectively, create dry workspaces for your crew
Specially engineered to divert water effectively, creating a dry workspace for both construction sites and commercial properties. The combination of our exclusive internal baffle with the overall design of the inflatable cofferdam ensures superior water control, stabilizing the surrounding area and securing a safe, dry environment for various applications.
Aqua-Barrier® is
versatile and certified
Aqua-Barrier® is not only a versatile solution, with system heights varying from 2ft up to 8ft controlling up to 6ft of water and sediment depth combined, but also comes with the assurance of quality – they are engineer-stamped and certified. This certification is a testament to their reliability and compliance with industry standards.

Determining Size Requirements
Disclaimer: Excess slope, high water velocities, dynamic loads resulting from wave actions, mounting surface irregularities, and changes in interrelated hydrological conditions can increase the required water inflated dam height versus retention height requirements.
