Introducing the Osmo Flood Barrier – a disposable flood control solution designed for quick deployment and effective protection. Lightweight and easy to store, it inflates on contact with water, making it ideal for garage doors, driveways, and more. Manufactured sustainably with at least 50% reclaimed materials, it's an eco-friendly sandbag equivalent, offering swift and reliable flood protection.

How does the Osmo Flood Barrier work?

The Osmo Flood Barrier is an innovative, super-absorbent disposable solution designed to create a water-tight defence against flooding. Available in 1.5m and 3m lengths, this barrier is activated by water, absorbing up to 30 litres, crystallising, and forming a water-tight barrier. Utilising super-absorbent technology, it binds together to create a flood protection sock, quickly deploying upon contact with water.
Lightweight, soft, and easily stored, the continuous sock-like shape reduces weak points, offering efficient protection superior to traditional sandbags. Made from at least 50% reclaimed materials, it's an eco-friendly, non-toxic, and non-hazardous flood protection option. The Osmo Flood Barrier is a versatile solution suitable for temporary flash flooding or long-term flood prevention.

How to use the Osmo Flood Barrier?

To use the Osmo Flood Barrier effectively, follow these steps:

  1. Prepare the Barrier: Ensure the barrier is stored in an accessible place near the area you want to protect, such as your garage door.
  2. Place in Position: Roll out the barrier in front of the door or opening you wish to protect. If using it for a garage, place it in front of the garage door.
  3. Activate with Water: The barrier activates upon contact with water. Simply wet the barrier with water, and it will start to absorb and expand.
  4. Allow Absorption: Once activated, the barrier will start absorbing water rapidly. It can absorb up to 30 litres of water for the 3-meter size.
  5. Form Protective Ring: For optimal protection, curve the barrier around the door or opening to create a protective ring. This helps to ensure that water is diverted away effectively.
  6. Stack for Additional Height (Optional): If necessary, you can stack multiple barriers on top of each other to increase the height of the protective barrier.
  7. Monitor and Adjust: Keep an eye on the barrier during flooding conditions. If needed, adjust its position or add more barriers for extra protection.
  8. Dispose After Use: Once the flooding has subsided, dispose of the barrier appropriately. Since it is disposable, you can discard it without any hassle.

By following these steps, you can effectively deploy the Osmo Flood Barrier to protect your property from floodwaters.

See how easy it is to use the Osmo Flood Barrier:


Please note, the Osmo barrier will not inflate with salt water, so should be inflated with fresh water before being used against sea water.

Customers are warned that whilst they may find they are able to inflate and deflate the barrier between floods, the product is designed for single use, owing to the biohazard nature of flood water.

When and where can you use the Osmo Flood Barrier?

You can use the Osmo Flood Barrier in various situations and locations:

  • Residential Properties: Protecting homes from flooding by deploying the barrier in front of garage doors, entryways, or basement doors.
  • Commercial Properties: Safeguarding businesses from floodwaters by placing the barrier in front of entryways, loading docks, or other vulnerable areas.
  • Driveways and Gates: Preventing floodwaters from entering driveways or gated areas by deploying the barrier across these openings.
  • Footpaths and Sidewalks: Keeping pedestrian walkways dry and safe during flooding events by placing the barrier along footpaths and sidewalks.
  • Diverting Floodwaters: Redirecting floodwaters away from properties by strategically placing the barrier to create diversion channels.
  • Temporary Flash Flooding: Using the barrier as a temporary measure during flash flooding events to quickly protect properties.
  • Long-Term Flood Protection: Implementing the barrier as a long-term solution for areas prone to flooding, providing continuous protection over time.

Using the Osmo Flood Barrier: A Step-by-Step Guide

To make the most of the Osmo Flood Barrier, adhere to these instructions:

  • Prepare the Barrier: Beforehand, ensure the barrier is conveniently stored in a readily accessible location near the area requiring protection, such as beside your garage door.
  • Positioning: Unroll the barrier in front of the designated door or opening that necessitates safeguarding. For instance, if safeguarding a garage, position it ahead of the garage entrance.
  • Activation with Water: The barrier springs into action upon encountering water. Simply moisten the barrier with water, initiating its absorption and expansion process.
  • Allow for Absorption: Once activated, the barrier promptly begins absorbing water at an impressive rate. For the 3-meter size, it can absorb up to 30 liters of water.
  • Creating a Protective Enclosure: For optimal defence, mold the barrier around the door or opening to establish a protective enclosure. This ensures efficient diversion of water away from the area.
  • Stacking for Additional Elevation (Optional): If required, you have the option to stack multiple barriers atop each other to heighten the protective barrier.
  • Continuous Monitoring and Adjustment: During flood situations, keep a vigilant watch over the barrier. If necessary, make adjustments to its positioning or add more barriers to fortify protection.
  • Disposal Post-Use: Once the floodwaters recede, dispose of the barrier appropriately. Since it is designed for single-use and is disposable, disposal is hassle-free.

By diligently following these steps, you can proficiently deploy the Osmo Flood Barrier, shielding your property from the ravages of floodwaters.

Observe the simplicity of utilising the Osmo Flood Barrier:


Please note, the Osmo barrier will not inflate with saltwater so it should be inflated with fresh water before use against seawater.

Customers are advised that although they may find it possible to inflate and deflate the barrier between floods, the product is engineered for single use due to the biohazardous nature of floodwater.

Insufficient expandable filling.

Half of the 3 meter barrier remained flat and did not contain enough expandable filling.

I bought 2 of the osmo flood barriers hoping they would stop water running down a corridor in our cellar. I emailed the company when they didn't work and had no response.
