Aluminium ‘Nautilus’ Flood Barriers

Aluminium ‘Nautilus’ Flood Barriers

The Nautilus 200 and 400 flood barrier systems are robust watertight aluminium flood barriers which can be quickly and safely deployed before a flood. Once the flood has passed, it is easily dismantled and stored away, ready for the next event.

The flood barriers are designed, engineered and manufactured in the U.K. They can span wide distances and are well suited for hostile environments.

The innovative and patented demountable aluminium flood barriers have been developed for both residential and commercial properties and have been installed on over 1000 properties across the U.K and internationally.

The barriers have been rigorously tested to comply with BSI Standard PAS1188 for demountable and building aperture flood defence barriers. The Nautilus 200 barriers have also passed independent testing for the new BSI Standard BS851188.

Using our in-house design team, the barriers can be made to bespoke dimensions.
The barrier system makes use of two permanently-fixed vertical side channels fitted either side of the opening to be protected.

We can also supply swing hinge metal flood gates. Please contact us to discuss your requirements.

Large Spans

For large spans, the Nautilus system makes use of pre-installed unobtrusive ground fixtures to allow the Patented Twist and Lock post system (Patent No. 2371068) to be put in place. The aluminium flood boards can then be dropped into position, creating an effective flood barrier for the required span.

Who we work with


The flood barriers are available in either ‘Reveal Fix’ or ‘Face Fix’, depending on the aperture and location.

  • ‘Reveal Fix’ means the rails are fixed in between the reveals (brickwork) of the doorway
  • ‘Face Fix’ means the rails are fixed onto the outer face of the brickwork. (Please allow an extra 200mm over the aperture width)

Our flood consultants work nationwide on both residential and commercial projects. We are passionate about flood defence and work closely with our clients to ensure the solution is not just appropriate for the property, but also the individual.

We present our findings in a report for you to peruse at your leisure. We follow a holistic approach and look at the issues the site or property is facing and adapt a mitigation plan to suit the client.

Fire doors must not be blocked by flood barriers. There are 3 main options:

  1. Internal fitment if outward opening.
  2. U-Shape area with 90 degree demountable posts.
  3. Construct walls to create a ‘pen’ to allow the door to open.

After 4 floods in 16 years, the Water-Gate Barrier was used in November and December 2012. The relief when it prevented what would have been a 5th and 6th flood was enormous. The best part is the piece of mind that follows.

I would not hesitate to recommend Flood Protection Solutions, a very professional and detailed service.
