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 awarded the contract and began works to carry out 300 metres of riverbank protection to protect this existing exposed high pressure gas pipe in March 2013.
Salix were tasked with greening up a 45 degree slope consisting of 6F2 fill. The initial design was a covering of 150mm of topsoil over an area of about 8,000m2 using a geocell product attached to the surface of the slope to contain the soil and prevent it from slipping.
Salix applied HydraCX in September 2009 to slopes consisting of 6I/J fill material with no imported topsoil covering the surface. The project was monitored each year to see how the vegetation established.
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 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.

In helping to re-model railways across the UK we have been met with some unusual challenges both in terms of the erosion problems themselves and the attendant access and safe working method issues.
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.
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.
HydraCX was sprayed onto 5,500m2 of re graded rail embankments to prevent erosion and establish vegetation rapidly without importing expensive topsoil. HydraCX also replaces erosion control geotextiles.
A rail embankment had slipped and was reinstated with soil nails providing geotechnical stability. Birse created working platforms with imported stone and then used a soil cell system to retain about 150mm depth of soil on slopes up to 43 degrees.
Works were required to repair an eroding railway embankment adjacent to the river. This resulted in the embankment encroaching into the river, causing erosion problems on the opposite bank belonging to a local farmer.
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.
