One L-shaped panel. A complete flood wall.

Each panel is a single injection-molded L-shaped unit — an upright wall joined to a horizontal base. As floodwater rises, the weight of the water presses down on the base, holding the barrier firmly in place. Panels lock together to form straight runs, corners, and full enclosures. No ground fixing, no tools, and a single worker can deploy up to 10 meters per minute.

Why it works

No anchoring, no tools — One person can install, lock, and remove each panel by hand.
Self-stabilizing — The deeper the water, the harder it presses the base down. The wall stays put without bending.
Reliable seal — A bottom memory-foam seal plus anti-slip strip stops seepage and can be reused.
Adjustable angles — The locking joint allows fine adjustment of ±3°; three corner panels form a 90° turn.
Stackable & interchangeable — Nest for compact storage; any matching panel type connects freely, so future replacements are simple.
UV-resistant — Tested under UVB-313 for 48 hours with no visible change.
