Salix have developed a Coir Roll which is fully biodegradable, providing effective erosion control without the use of plastic nets.
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.
Rock Rolls and pre-planted Coir Rolls & Pallets were used to prevent erosion whilst creating a lovely habitat in Sheffield City centre where a culverted stream had been flash flooding
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 have been appointed as specialist contractors to deal with the erosion control and habitat creation within a SuDS for a mix of housing and business parks at The Avenue
Our Coir Rolls are superb at erosion control and they are also brilliant for wildlife. Wildlife such as Water Voles benefit enormously from the immediate cover that the mature plants provide and also from the carefully thought out planting.
Bridging the ecological and engineering gap with our effective bio-engineering solutions
Rock Rolls offer flexibility and the fact they arrive on site pre-filled with stone greatly reduces installation time and therefore cost, compared to in-situ filled gabions. Rock rolls and mattresses can also be installed during live flow situations, which is not possible with standard gabions.
Salix’s Technical Director David Holland visited Sri Lanka over Christmas with his family to see how coir fibre production is shaping up.
The South Downs National Park Authority has commissioned Salix to help create a wildlife haven on the South Pond, at the edge of Midhurst town centre in West Sussex. The large 800-year old pond, which has a 270-metre perimeter and two small islands, had been suffering from pollution and heavy siltation.
Working directly with ethical, organic and sustainable suppliers in Sri Lanka, each year Salix imports hundreds of tonnes of compressed coir fibres and turns them into Coir Rolls and Pallets at its Thetford nursery in Norfolk.
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…
Coir Rolls are an organic living revetment that provide erosion control and rapid vegetation establishment. Salix have developed a range of specific species mixes for use in all types of water bodies.
Rock Rolls are a robust, flexible and permanent revetment for use around reservoirs, shorelines, lake edges,
We are delighted to finally unveil our role in making the Olympic Park a reality, from our initial involvement way back in 2008,
The current harsh winter conditions have frozen our 20 acre constructed wetbeds at our own nursery in Norfolk.
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.
Over 560m of perched channel in Soham, Cambs was leaking and needed repair. The reach was populated by water vole so a sensitive approach was required in order to create a new habitat as soon as possible.
Client – Environment Agency
Pilot scheme for catchment restoration of the River Ecclesbourne, that forms part of the Water Framework Directive aim to return rivers to good ecological status.
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.
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.
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.
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.
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…
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.
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.
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…
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.
