Flooding and erosion prevention in Sheffield

Porter Brook - an oasis for wildlife

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.

Flashy Floods in Car Park Solved

Coir Rolls pre-established with native plants providing erosion control at Porter Brook

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

Coir Rolls Aid Biodiversity Boom

Selection Of Unplanted and Pre-Established 200mm and 300mm Coir Rolls

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.

Rock Rolls – Effective Erosion Control

Rock rolls arrive in bundles with certified lifting straps

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.

Lake Desilting & Biodiversity Improvements at Midhurst’s South Pond

Revetments at Midhurst

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.

Salix is now Europe’s largest producer of coir fibre rolls

coconut husks

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.

Darwen Bank Stabilisation

One Year Later. Note the Reed Canary Grass (Phalaris arundinacea)

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.

Olympic Park Wetlands

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

Selection Of Unplanted and Pre-Established 200mm and 300mm Coir Rolls

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.

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

Chaser on river restoration

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.
