About Us

River restoration and erosion control specialists

Salix provide sustainable solutions to the challenges found in soil erosion control and river restoration projects. We also specialise in spillway and shoreline protection, inland dredging and wetland habitat creation schemes.

Utilising innovative bioengineering solutions, often replacing hard engineering, allied with our capabilities in more traditional civil engineering techniques, we build with nature to deliver cost effective, environmentally sensitive solutions.

Salix are a designer, constructor, manufacturer, distributor and grower rolled in to one single company – unique within the UK construction industry.

Therefore our clients can get a holistic, cost-effective service from one main source.

Our approach complements the natural environment, adds to biodiversity and improves water quality.

Specialist Contracting

Either operating as a principal design & build contractor or a specialist sub-contractor, Salix are able to field our own plant and experienced installation teams, supported by strong in-house technical support.

Erosion Control Materials

We manufacture and supply a broad range of soil erosion control and bioengineering products with performance led specifications that allow engineers to specify with confidence.

Working closely with companies from France, Germany, Holland, Spain and Scandinavia allows us to expand our knowledge base and expertise. Collectively the members of ESWEG have completed over 1000 bioengineering projects.

ESWEG are responsible for new, innovative products within the industry and carry out extensive research and independent testing. Further afield, Salix also have a close relationship with bioengineering companies in the USA and enjoy exclusive UK rights to the North American Green erosion control product range, now also manufactured in Europe.


“We used HydraCX for the first time on a Network Rail project in Chipping Campden. We wanted to establish vegetation growth as quickly as possible on a slope with poor ground conditions without the need for importing topsoil due to possession time constraints. HydraCX provided an excellent growing medium for rapid germination.” Carillion Rail

“HydraCX gave an immediate impression the embankment was grassed, making it more visually pleasing to our travelling customers. The rapidity of grass growth was exceptional and it added additional strength to the slope surface.” Network Rail

“We invited Salix to re-landscape the watercourse through a design and build project. The works to the watercourse were completed within two weeks of starting on site and, despite a number of prolonged heavy rain events both during and after the works, the pre-established coir rolls and pallets all began putting on new growth within a matter of days providing the watercourse with instant channel vegetation and protection to the toe of the banks. The VMax reinforcement used to stabilise the slopes has also prevented any erosion to the sandy soil beneath and has allowed the rapid establishment of grass which wouldn’t have otherwise been possible.” South Ribble Council

“Atkins has worked with Salix on a number of projects, collaborating on design concept, trialling and implementation. We have found their experience valuable in delivering cost effective and environmentally functional solutions.” Atkins

“We have worked with Salix on a number of projects throughout East Anglia over the last 6 years, and we have always found them to be highly professional and competent. We have used their services as suppliers of quality wetland plants, with a traceable provenance, and as contractors to both supply and plant the wetland plants. In addition we have always relied on the technical advice and knowledge of David Holland, in particular, to help answer queries from our clients regarding wetland planting schemes we have been involved in, this is an added value part of their service, for which we are grateful.” UPM Tilhill

“Excellent overall performance – very approachable and offered a good sustainable solutions to rectify a significant erosion scour to the river foreshore without comprising the existing flood defence. Carried out work to agreed timescale and budget. Certainly would value their future input.” Environment Agency, Leeds

“Your staff are always friendly, knowledgeable and helpful and we have always been pleased with the service and the quality of the wetland plants and planting services. Technical knowledge on erosion control is also excellent. Keep up the good work!” Living Water Ecosystems Ltd
