Network Rail had identified an erosion and scour risk at the toe and embankment of one of their assets on the River Leith, near Thrimby, Cumbria.
Soft engineering solutions presented by Salix, such as Coir Rolls, Rock Rolls and shear stress turf, represent a major cost saving over traditional hard revetments
Jack’s Keys needed a rapid response to scour and erosion problems.
Our pre-filled Rock Mattresses and Rock Rolls were the answer, our Menzi Muck Spider machine was able to climb in and place them in the river bed.
Creating a reed bed on an intertidal part of the Thames river is challenging – but Salix achieved a fantastic result as a consequence of their unique design approach.
When a flashy stream was unearthed in Sheffield Salix were brought in as specialist experts in erosion management by the Wild Trout Trust. The Porter Brook was subject to regular flooding, if it rained on the Peaks then the city centre would flood.
We installed erosion protection products like our Coir Rolls and Rock Rolls at this site where a pipeline was exposed in the river bed
Salix’s erosion management products used in works to repair flood defences. Rock Rolls, Coir Rolls, native wetland plants and VMax C350 were all essential ingredients.
Rock Rolls and Rock Mattresses are both easy to put into place, prevent erosion and can withstand high flows whilst allowing for the natural establishment of plants.
Constant flooding and erosion had been causing some serious problems for Merthyr Tydfil Council who manage an old reclaimed tip site, close to the village of Bedlinog in the Taff Bargoed Valley.
The aim of the project was to protect around 100 houses and businesses that had been subjected to increased flood threats. Constant flooding was a problem with this very flashy river where it passes through the town.
The increasing frequency of flood events on the River Washford required the existing system to be replaced and improved.
A 120 metre reach of river had been subject to ongoing bank instability issues. A gas pipeline set in the bank was dangerously close to being exposed and bank revetment options were considered.
Working for Bournemouth & West Hants Water, Salix were appointed as Main Contractor to undertake 2km of bioengineering works to stabilise the shoreline of a new reservoir.
Works were required to repair an eroding railway embankment adjacent to the river. This resulted in the embankment encroaching into the river, causing erosion problems on the opposite bank belonging to a local farmer.
Salix worked with consulting geotechnical engineers to provide design and build proposals to stabilise over 800 metres of steep riverbank composed of highly erodible colliery shale.
A private developer had back gardens adjacent to a river that when in flood created severe scour issues. Initial river modelling indicated flow velocities in excess of 3.5m/sec.
Salix were invited to submit a bioengineering solution to solve an erosion issue at a pipeline crossing in West Wales. The solution used a combination of locally harvested willow and Rock Rolls to provide a stable revetment in this cobble bed river.
Salix advised engineers Halcrow on bioengineering methods to stabilise a regraded slope as part of an inter-tidal river enhancement project. The existing vertical retaining wall provided no habitat value.
A two hectare area of open water had extensive embankment erosion due to massive populations of Canada Geese which created public health & safety issues.
A new development had slope stability issues due to an adjacent cobble bed watercourse badly eroding the soils and downcutting the bed within the channel.
The River Teme is a sensitive SSSI and SAC river and over 150 metres of severe bank erosion was threatening a National Grid pipeline.
