Water-Gate Flood Barriers

Rapid Flood Barriers

The Water-Gate are temporary flood barriers which are unique in the way that once rolled out, they self deploy.

It uses the weight of the water to hold the water back. The water lifts the top of the barrier whilst at the same time weighing the base down, forming a seal. By utilising this unique self-opening method, it reduces the time, effort and number of people required to install it, making this a truly rapid flood or water diversion barrier.

It is highly portable and takes up limited storage space. The flood barriers are highly effective in strength, stability, function, ease of deployment and storage when compared with other flood defence products on the market such as sandbags, water filled barriers, booms etc. It is very versatile and can be used on flat or uneven surfaces.

We believe the system can provide an efficient and effective fast response resource when dealing with emergency response situations.

The flood barriers are already used by homeowners, Water Companies, and the Environment Agency.

Water-Gate Cross Section

Depending on the model, the weight exerted by the water is up to 4 times more in the vertical than horizontal, thus ensuring the security of the barrier on the ground. It has been designed and tested to work on surfaces including gravel, grass, asphalt, etc.

The 3 typical Water-Gate flood barrier protection setups

Thanks to the Water-Gate’s modular design, units can be joined together to create the desired length. They can be used on different terrains, offering protection between two walls or an embankment, as a u-shape on sloping terrain, or for 360° protection around a site. It is important to make sure that the barrier is not outflanked.

Water-Gate Barriers take up limited storage space and can be loaded into a vehicle for transport to site.

Single barriers come in a roll for easy storage and quick deployment. Barriers can be supplied pre-joined for rapid deployment for long lengths, in made to measure boxes. Depending on the size, the boxes can be supplied on wheels, or moved by forklift, pallet truck or trailer.

FM Approval

Singular barriers come in a roll for easy storage and quick deployment. In September 2015, the Water-Gate WL Flood Barrier was awarded FM Approval, a worldwide accreditation. This was following extensive testing by the US Army Corp of Engineers. The barrier was subjected to a full riverine test, along with factory inspections, where all the individual components and processes were inspected.

The Water-Gate was tested as a Temporary Barrier and obtained Silver certification from FM Approvals. Products with FM Approval are recognised around the World as temporary flood risk reduction products. The Water-Gate has proved itself to be an effective tool in both real life situations, along with extreme testing. WL39, WL50 and WL60 barriers are accredited.

Flood Barriers Cost Comparison with Sandbagging

It is a common misconception that sandbags are a cost-effective method of flood defence.

Sandbags are often used as a defence method for flooding, but their success is questionable at best.
In Sir Michael Pitt’s review of the 2007 floods he states ‘The Review was unable to obtain any significant evidence that sandbags were particularly effective during the 2007 summer floods’. Sandbags can be used effectively as weights, but surely it is time to embrace the newer proven Water-Gate barrier?

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.
