SPECIFICATION
DamGuard-inc™ Removable Aluminum Plank Barriers
Modular | Lightweight | Reusable Flood Protection
General Description
The DamGuard Removable Aluminum Plank Barrier System is a modular flood defense solution for doorways, storefronts, garages, and industrial openings. Using stackable aluminum planks secured in side posts, the barrier creates a watertight seal against floodwaters.
When not needed, planks are removed and stored, leaving only low-profile side channels in place — maintaining a clean architectural finish.
