FREQUENTLY ASKED QUESTIONS
Before you choose
your garage barrier.
How much water can the barrier hold back?
The standard three-panel configuration provides a design water height of approximately 26 inches (2.2 ft). Taller configurations require review for your opening and site conditions.
How long does it take to deploy?
Once the permanent side channels are installed, the numbered panels stack and lock in minutes. WDS describes typical deployment as about 10 minutes per opening. Practice before a flood warning.
Can I set it up myself?
Yes. The system is designed for manual deployment using the supplied Allen keys. Follow the deployment guide and arrange for a trained person to install the panels before water reaches the opening.
How do I maintain the barrier?
Rinse with clean water after use, dry thoroughly and store indoors. WDS recommends inspecting the seals twice a year and checking the system before every deployment.
Will it affect the look of my home?
Slim side channels remain installed at the opening. The panels are removed and stored when not in use. We review mounting positions and clearances with you.
Can it protect more than garage doors?
WDS offers configurations for doors, storefronts, windows, stairwells and other openings. Suitability, mounting conditions and required exits must be reviewed for each location.
What warranty applies?
WDS lists a five-year product warranty for panels, posts and hardware, and three years for seals, subject to its written terms. Its one-year installation warranty applies to WDS installations; Poseidon installation scope and workmanship terms are provided separately in your proposal.

Barriers help resist water at the designated protected opening within their design limits. They do not make the entire property waterproof or guarantee against flood damage. Water can enter through other parts of the building, and some leakage may occur. Read the full protection scope.
