Water Fillable Barricades

Flood & Construction Cofferdams

These engineer-certified vinyl barriers inflate with site water to form a reusable barricade. A built-in baffle system locks the barrier’s shape, ensuring consistent stability on uneven ground.


Designed for fast deployment, the water barrier requires minimal labor and no heavy machinery. Constructed from UV-resistant, industrial-grade material, each inflatable cofferdam provides an eco-friendly alternative to sandbags and sheet piles.

Cofferdam Product Applications


Inflatable cofferdams serve two primary purposes: temporary flood protection and construction dewatering. Learn more about each application using the links below or contact One Clarion's team to get a free quote for your project today.

  • Temporary Flood Protection – Deploy water fillable barricades to shield buildings and infrastructure from rising water without permanent structures.
  • Construction Dewatering – Create a dry work area around excavations, foundations, and trenches with rapid-deploy cofferdam barriers.

Looking for a Budget-Friendly or Temporary Solution?


Whether you have a one-off project or ongoing dewatering needs, our water-inflated cofferdams can be rented or bought to match your budget and schedule.


  • Rent: Temporary cofferdam construction keeps upfront costs low with on-demand flood barriers for short-term work.
  • Buy: Invest once and reuse your cofferdam across multiple construction dewatering and flood protection projects.
