Demountable and Temporary Flood Barriers

Grein (Austria)

Flooding of the Danube in 2013
in the region of Grein (Austria)

General data

  • Length: 765 metres
  • Max. height: 4.60 metres
  • Wall surface area: 2450 m²
  • Protection objective: 15 metres
  • 2013 filling level: 14.95 metres

History of the project

One of the highest and most spectacular mobile walls to date, it was finished in August 2012. Its reference height of 3.6 metres (4.6 metres at its highest point) above ground level makes it one of the tallest flood-defence walls of its type ever to be made by IBS. When the Danube burst its banks in 2013, the IBS defence wall was tested to the limit and came through with flying colours.
