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.
Following the 2005 £2million Lhanbryde Flood Alleviation Scheme, near Elgin in Moray, in Summer 2014, Salix worked with Royal HaskoningDHV engineers to improve erosion control on the dam’s spillway.
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,
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.
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.
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.
The River Teme is a sensitive SSSI and SAC river and over 150 metres of severe bank erosion was threatening a National Grid pipeline.
