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.
In 2009 Team Van Oord installed 9000m2 of Salix’s VMax Shear Stress Turf as part of the Conwy Flood Alleviation Scheme, seven years and many major overtopping events on and it has stood the test well.
The increasing frequency of flood events on the River Washford required the existing system to be replaced and improved.

Bridging the ecological and engineering gap with our effective bio-engineering solutions
Our Technical Director, David Holland, has been in the most recent edition of CIWEM’sThe Environment Magazine talking about the value of our 3D reinforced turf mats in erosion control.
Erosion control using Tensar VMax P550 on Loch Garry spillway and embankments
Tensar VMax P550 is designed for use as erosion control on steep slopes, high-flow channels, spillways, and shorelines.
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 reviewed the options for improving water control and biodiversity at Nant Llwynog stream – an old reclaimed tip site close to the village of Bedlinog in the Taff Bargoed Valley.
Salix have the facilities to contract grow turf using the VMax range of Turf Reinforcement Mats (TRMs). VMax C350 or P550 is used as the reinforcement element within the turf giving unprecedented scour protection performance.
VMax³ P550 is composed of a permanent, ultra-high-strength, three-dimensional matting structure incorporated with a permanent 100% polypropylene fibre matrix.
VmaxC350 is a permanent Turf Reinforcement for reinforcing soils. The VmaxC350 incorporates a coir fibre layer to provide instant erosion protection, whilst the three-dimensional grid provides significant long-term protection.
We are delighted to report that Balfour Beatty have included our Eronet C125 and VMax C350 erosion control solutions and our Rock Mattresses in their Innovation Sheets.
The River Washford runs through the village of Roadwater near Minehead, Somerset. The catchment creates a flashy river which floods parts of the village in large flood events.
Salix are pleased to announce that We have been appointed as the sole distributors of the VMax® range of soil erosion control products formerly known as North American Green.
Salix have extensive experience of spillway protection offering advice to engineers involved in this area of expertise.
Our VMax range of Composite Turf Reinforcement Mats (CTRMs) including VMax C350,
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.
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.
Salix supplied 9000m2 of VMax3 Shear stress turf in September 2009. Just 2 months later the area experienced the worst flooding in 25 years of recording with floods exceeding the 1:30 year events of 2004/2005.
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.
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.
The River Teme is a sensitive SSSI and SAC river and over 150 metres of severe bank erosion was threatening a National Grid pipeline.
