Wetlands were excavated as part of a large, new retail development near Doncaster. Once excavated, the embankments suffered from significant erosion due to sandy soils and wave action. The structural integrity of the embankment was at risk, which would lead to failure of a bund and continued erosion.
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
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.
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.
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.
Salix were involved in making the Olympic Park a reality, when we were awarded the prestigious Tier 2 Contract in 2009 to grow all the wetland and wet wildflower plants…
The Wilderness Lake is an important coarse fishery and recreational resource on the edge of Porthcawl in South Wales. It also functions as a flood storage area for the surrounding urban areas.
The boating lake was a popular local attraction and fishing lake. The lake edges were in bad repair with little or no marginal vegetation. Floating islands were also required to add further habitat for fish and wildfowl.
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.
A rise in pleasure boating on the Foss resulted in severe boat wash. Monitoring revealed that the rate of bank erosion was up to 2.5 metres in a year over a 2km stretch.
1 km of new and existing channel was enhanced using bioengineering techniques as part of a flood protection project in the centre of historic Pembroke in West Wales.
Salix designed and constructed a stream enhancement project at a gas pipeline river crossing as ecological mitigation to a degraded reach of stream as part of a major pipeline project.
Salix were asked by Environment Agency Wales to advise on methods to restore a 100 metre reach of the River Thaw which had been subject to physical degradation by overgrazing and cattle poaching.
Salix were employed by main contractor Casey to undertake the restoration work to Beacon Pool for Lichfield Council on this Heritage lottery funded project.
Salix were contracted by Mansell construction to dredge the contaminated Goit forming Kelham Island and working closely with ecologists ECUS to create marginal habitat.
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.
A two hectare area of open water had extensive embankment erosion due to massive populations of Canada Geese which created public health & safety issues.
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.
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…
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…
