Reservoir Dogs – Shoreline protection

Early germination of grass seed through VMax C350

Salix were brought in to help with a sensitive erosion problem on a reservoir shoreline in North London. Ecologically sensitive solutions were used which will create habitats and improve amenity value.

Naturalising a Stream at Bedlinog

Bedlinog post works with riffles and more natural flows

Constant flooding and erosion had been causing some serious problems for Merthyr Tydfil Council who manage an old reclaimed tip site, close to the village of Bedlinog in the Taff Bargoed Valley.

Flood Alleviation at Tregaron

Tregaron July 2016

The aim of the project was to protect around 100 houses and businesses that had been subjected to increased flood threats. Constant flooding was a problem with this very flashy river where it passes through the town.

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.

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.

Ramsden Bellhouse

Ramsden Bellhouse Embankment

A series of potentially dangerous deep seated failures on a railway embankment required treatment to prevent further slips. The geotechnical issues of ground stability were resolved using soil nailing.

River Ebbw Bank Stabilisation

River restoration

Salix worked with consulting geotechnical engineers to provide design and build proposals to stabilise over 800 metres of steep riverbank composed of highly erodible colliery shale.

River Gwenfro

Fully Established Bioengineering Solution Replacing Gabion Design

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.

Calverton Tip Drainage

Calveton tip drainage

Colliery shale and sandy soils have one thing in common; both are highly susceptible to erosion by flowing water. Both soil types were present on site.

Waverley Colliery Reclamation

C350

A large drainage channel designed to take flows of up to 3m/sec was created to take runoff water from a 741 acre site at Waverley, one of Europe’s biggest collieries.

Treboeth Cobble Channel

Treboeth cobble channel

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.

River Teme Restoration

River Teme Restoration

The River Teme is a sensitive SSSI and SAC river and over 150 metres of severe bank erosion was threatening a National Grid pipeline.
