Nautilus® 400 demountable flood defence barriers are the ultimate flood protection for commercial and industrial premises, including factories, warehouses, loading bays/docks, driveways and garages.

Flood defence barriers and other flood prevention products to protect your business are certainly a very good idea. Whether you’re looking to reduce your insurance premiums or obtain refused insurance cover. In any event, we would like to help you protect your property.

Without a doubt, the easiest way to learn about our flood defence products is to watch any of our videos. You will find a one minute video on each of our product pages.

This robust removable flood barrier system spans 2.5 metres between demountable posts.
The temporary flood barrier panels are much thicker than those of the Nautilus® 200. Therefore the Nautilus® 400 is our strongest flood defence barrier system

  • Suitable for residential, commercial and industrial properties.
  • Designed with a watertight sealing system.
  • Lightweight aluminium temporary flood barrier panels.
  • Following the initial installation, assembly for the client is indeed quicker and simpler than the Nautilus® 200 system.
  • Flood barriers for single doorways do not require demountable posts. Assemble in minutes by one person.
  • Whereas a six-metre wide flood barrier uses two demountable posts and assembles in seven minutes by one person. Please see the short video on this page.
  • From flood warning to flood protection in a matter of minutes, providing peace of mind.
  • Afterwards, the flood barrier dismantles and stores away easily, ready for the next flood event.
  • Designed and manufactured in the UK to the highest standards.
  • Competitively priced with speedy delivery.
  • Supply only option available.
  • Undeniably, the survey and installation service provided by our highly experienced mitigation engineers is one of the best in the UK.
  • Additionally, we provide exceptional ongoing customer support.
  • To protect an area wider than 2.5 metres:
  • Two permanently fixed vertical rails, installed at each side of the opening.
  • Ground sockets are installed, protected by aluminium dust caps when the barrier is not in use.
  • When a flood threatens, insert the de-mountable posts into the ground sockets, then slide in the horizontal aluminium panels. Then apply the compression system.
  • The panels are each 400mm high.
  • Flood barrier up to 1600mm high for assembly.
  • Flood barrier of any required width created by installing demountable posts at every 2500mm.
  • Each panel is 25mm in thickness.

The Nautilus 200 and Nautilus 300 systems hold the PAS 851188-1:2019 Accreditation, complying with the British Standard BS851188.

The Nautilus 400 is a more robust system. It is an enhancement of the 200 & 300 system and has been installed for more than 95% of our clients, including the councils on our about us page.

BSI has confirmed that the 3 systems; Nautilus 200, Nautilus 300 and Nautilus 400 can be classed as a family of barriers, as they have the same matrix, so would include the 400 system.

The independent testing was done to the specification of BS851188 in February 2021, and the testing video can be seen HERE.

It is worth checking with your local council to see if you may be eligible for a grant.
