How do the water filled barriers work?

a diagram showing a an Aqua Barrier in action.

Three components act together to stabilize the Aqua-Barriers™:

INTERNAL BAFFLE SYSTEM - The patented internal baffle(s) locks into place when the barrier is exposed to uneven water pressure.

FREEBOARD - The amount of inflated barrier above the surrounding water level is called freeboard. A minimum of at least 25% freeboard is required in all Aqua-Barrier™ installations.

SURFACE FRICTION - Aqua-Barriers™ also require surface friction to stabilize when exposed to uneven water pressures. Barriers that are exposed to weak soils and/or slick conditions may require additional freeboard.

What are the barriers made of?

Aqua-Barriers™ are constructed from industrial grade vinyl coated polyester. This fabric is laminated with a base of woven polyester between two layers of flexible polyvinyl chloride.

What does this mean to you? These units can be REPAIRED EASILY in the field in wet or dry conditions, they are REUSABLE, and they offer compact storage and transportation along with ease of handling.

What sizes are available?

Inflated heights are 2-feet through 8-feet and standard lengths are 25-, 50-, 75- and 100-feet. See the chart below for standard sizes. Custom sized units are available upon request.

How do the barriers connect?

Each inflated Aqua-Barrier™ section is straight without the ability to bend. When joining the sections, an OVERLAPPING TECHNIQUE is used.

This gives you the option of creating a formation to fit your project needs. We will help you determine what is required, so that you save time during the installation.

You will simply place the barrier to be inflated on top of the end of the inflated barrier and begin the installation process. The amount of overlap is determined by height, as indicated in the chart below:

Aqua-Barrier
Inflated Height (ft/m)
Overlap Length (ft/m)
2 / 0.61 3 / .91
3 / 0.92 4.5 / 1.37
4 / 1.22 6 / 1.83
5 / 1.53 7.5 / 2.29
6 / 1.83 9 / 2.74
8 / 2.44 12 / 3.66
