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.

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.

Sandwich Flood Alleviation and Spillway Scheme

The £21.7 million flood defence scheme involved works on 16 individual reaches of the river and it reduced the risk of tidal flooding to 488 homes and 94 commercial properties in Sandwich. Client – Jackson Civil Engineering working on behalf of the Environment Agency.

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.

Salix produce a wide range of pre-established coir pallets planted with high quality native plant species. Coir pallets are composed from coir fibre which is a sustainable waste product from the husk of the coconut shell.

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.

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 between Selsey and Bracklesham in West Sussex.

Rock’n’Roll!

Rock Rolls are a robust, flexible and permanent revetment for use around reservoirs, shorelines, lake edges,

Cwmbran Boating Lake

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.

Foss Dyke Bank Stabilisation

Bank Stabilisation

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.

Pembroke Commons

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.

River Pinn Enhancement

River restoration works

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.

Pre-filled Rock Roll

Rock rolls provide an instant flexible solution to many scour problems

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.

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.

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.
