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.
River Ebbw Bank Stabilisation
vegetation establishment
River Gwenfro
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.
River Roding Bank Protection
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.
River Roding Enhancement
The River Roding is an inter-tidal river and these works were undertaken 100m upstream of the Barking Barrier, Greater London. The works were part of an Environment Agency environmental enhancement project with both flood defence and nature conservation in mind.
Dan Y Lan Landfill Slip
The finished slope was 36 degrees, 40 metres in height and 60m wide. 250mm depth of topsoil was required, rather than the nominal 50-75mm, as cover for marginally contaminated on site fill material.
Calverton Tip Drainage
Colliery shale and sandy soils have one thing in common; both are highly susceptible to erosion by flowing water. Both soil types were present on site.
Waverley Colliery Reclamation
A large drainage channel designed to take flows of up to 3m/sec was created to take runoff water from a 741 acre site at Waverley, one of Europe’s biggest collieries.
Pre-filled Rock Roll
Rock Rolls are a robust and permanent revetment for use around reservoirs, shorelines, lake edges, streams and river banks. They are cost-effective revetments that are suitable alternatives to rock rip rap and gabions in many scour applications.
Pre-filled Rock Mattresses
Rock Mattresses are a robust and permanent revetment for use around reservoirs, shorelines, lake edges, streams and river banks. They are cost-effective revetments that are suitable alternatives to rock rip rap and gabions…
Beacon Park
Salix were employed by main contractor Casey to undertake the restoration work to Beacon Pool for Lichfield Council on this Heritage lottery funded project.
Kelham Island Goit
Salix were contracted by Mansell construction to dredge the contaminated Goit forming Kelham Island and working closely with ecologists ECUS to create marginal habitat.
Water Vole Habitat Works
Salix successfully tendered for a pilot project to improve marginal vegetation along the River Wandle. The project formed part of a wider scheme to reintroduce water vole to the river.
Upper Lake, Perton
A two hectare area of open water had extensive embankment erosion due to massive populations of Canada Geese which created public health & safety issues.
Grand Union Canal
The project aim was to restore a wetland area on the banks of the Grand Union Canal for the benefit of wildlife and the fishery. The scheme design ensured that no material was taken off site and that particular focus was on creating suitable habitat for Water Voles and amphibian species such as Newts.
Treboeth Cobble Channel
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.
Soham Lode Re-visited
An important water vole site at Soham Lode required emergency re-lining of the perched section of the reach (approximately 600m) Following the emergency works, Salix were awarded a Design & Build contract on a competitive bid process…
Water Vole Habitat Mitigation
Medmerry is one of the stretches of coastline most at risk of flooding in southern England. The overall scheme involves building major new sea defences inland and allowing a new intertidal area to form…
Worden Park Leyland
Following works within Worden Park to remove a culverted section of Cricket Field Brook that was the cause of flooding to neighbouring residential properties, a long term solution was required…
Floating Islands
Floating Islands provide valuable ecological habitat, fish refuge cover and water purification within open water environments. Salix supply and install floating islands and can incorporate a diverse range of flowering species to increase the habitat and aesthetic value of the project.
Live Willow Revetments
Living willow has been used as a method of controlling riverbank erosion for centuries. Salix employ traditional techniques and more modern approaches based upon the site specific erosion process.
Brushwood faggot/fascine
Salix produce a range of brushwood faggots (fascines) for use in rivers, canals and lakes. We use brushwood from sustainable sources and can supply various timber types including Ash, Hazel and Willow.
Railway Lane, Lewes
The integrity of the existing blockwork facing was deteriorating as a result of the tidal inundation and draw-down cycles together with areas of groundwater seepages emanating from the slope profile.
River Teme Restoration
The River Teme is a sensitive SSSI and SAC river and over 150 metres of severe bank erosion was threatening a National Grid pipeline.
