Brockley Whins Embankment Stabilisation

A complex emergency embankment stabilisation scheme at Brockley Whins Station comprising a 15,000 tonne berm and a 13m long 9m span Multiplate Arch culvert extension.

At the centre of the site a twin bore masonry arch culvert (Bridge 282), carries the River Don beneath the embankment flowing northwards.

All previous interventions had varying levels of success, but ultimately failed to halt ground movements…
