How do the water filled barriers work?
Three components act together to stabilize the Aqua-Barriers™:
INTERNAL BAFFLE SYSTEM - The patented internal baffle(s) lock into place when the barrier is exposed to uneven water pressure.
FREEBOARD - The amount of inflated barrier above the water level is called freeboard. A minimum of at least 25% freeboard is required in all Aqua-Barrier™ installations.
SURFACE FRICTION - Aqua-Barriers™ 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.

How do the barriers connect?
Each inflated Aqua-Barrier™ section is straight. When joining the sections, an OVERLAPPING TECHNIQUE is used.
This gives you the option of creating a formation to fit your project needs. You will simply overlap the barriers and begin the installation process. The amount of overlap is determined by height, and is listed 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 |
