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 on allowable leakage rates for demountable and building aperture flood defence barriers.

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.

  • Used on both residential and commercial properties
  • Suitable for doorways, or large lengths with demountable posts

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.

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

For an indicative price for supply, please provide us with the width of the aperture. If you are able to send a photo by email, it is most helpful. If you would like an installation quote, please provide us with your postcode too.

Whilst we can provide indicative quotes by from our head office, we do recommend having one of our flood risk engineers visit the site to ensure the best mitigation options are proposed.



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.
