Passive Automatic Flood Barrier

Hands-Free Protection Against Rising Waters

When it comes to flood protection, people want solutions they can trust without having to think twice. In an emergency, there isn’t always time or manpower to set up equipment, and relying on electricity or human action leaves too much to chance. That’s why automatic, self-activated protection has become the standard of reliability. With a passive automatic flood barrier that deploys on its own, you gain peace of mind knowing your property is protected 24/7, even if no one is there to respond. No electricity, no manpower, and no time lost.

How It Works

This innovative system is permanently installed at your property and lies flush with the ground when not in use. As floodwaters rise, the automatic flood barrier automatically lifts into place using the force of the water itself. Once the danger has passed, it returns to its resting position, leaving entryways clear and unobstructed.

  • No Power Required – Operates purely through hydrostatic pressure.
  • Hands-Free Activation – Deploys automatically, even when no one is on-site.
  • Unobtrusive Design – Remains hidden and accessible until needed.
  • Automatic Reset – Returns to its resting position after the flood recedes.
  • 24/7 Protection – Always on standby, ready to respond to unexpected flooding
