A unique product

The EUR180 Steel barriers ability to dam floods up to 1.80 m is rare. Few other flood defences have proven to do this. The design of Geodesign Barriers with connection rods, wide support bottom beams and an optimal angle enables the system to work perfectly even at deeper water levels.

The Geodesign Barriers have been on the market for over 12 years and have a perfect record. They have been sold and used at multiple locations in Europe and Australia.


Quick and easy to assemble in 4 steps

The EUR180 Steel barrier is easy to assemble. It is easy to understand and no tools are needed. No parts weigh more than 40 kg which makes it possible for two persons to assemble the barrier. With 15 people, 650 m of the EUR180 Steel barriers can be deployed in 3 hours.

1. Flat packed EUR180 metal supports placed in the barrier line

The flat-packed EUR180 metal supports are placed evenly distributed on the ground along the desired barrier line. The supports are then unfolded by simply lifting the front beam up and placing the three supporting beams into position.

2. EUR180 Metal supports connected using the connection rods

Once the supports are unfolded and in place they are connected with the connection rods. They form a strengthening and connecting ‘brace’ through the whole construction – holding everything together.

3. Aluminum sheets placed onto the supports

The aluminum sheets are first placed so they lean on an edge of the connection rods. The sheets are then secured by aluminium locks that are pushed into the quadratic holes of the connection rod.

4. Plastic membrane rolled out

The plastic membrane is then rolled out over the deployed metal barrier. Sealer clips on top of the barrier together with a ‘girland chain’ along the barrier ensure that the plastic membrane stays in place before the water gets there. On the outer edge of the plastic membrane, a line of chain is placed, to hold the membrane down before the water pressure does the job.

EUR101 Test – Inspecta report

Inspecta is the leading provider of inspection, testing, certification and technical consultancy services in Northern Europe. Geodesign contracted Inspecta to verify a test of the new EUR101 Steel barrier. The purpose was to see if the barrier could withstand the pressure of extreme flooding scenarios. Inspecta’s report concluded that the EUR101 Steel barrier is well suited for the most extreme flooding conditions and that overtopping or moving water does not affect the stability of EUR101 Steel Barrier.

The test was carried out on 28 September, 2015 in Västervik, Sweden.
