Severn tests demountable flood barriers

News

Demountable flood defence barriers have been put to the test for the first time by the Environment Agency.

They were used to hold back the River Severn, after it burst its banks in Shrewsbury.

The demountable aluminium barriers are bolted onto stainless steel baseplates cast into a reinforced concrete ground beam.

This beam sits on top of a 3m high concrete flood defence wall, which is supported by sheet pile foundations.

The £6M scheme was carried out by Dean & Dyball and designed by Black & Veatch, following the severe floods of autumn 2000.

The barriers are manufactured by German company Bauer Innercity.

Similar barriers were erected at Bewdley last year but flood waters did not rise high enough to put them to the test.
