Geotextile and River mattress foundation laid – 27 September 2011

The geotextile layer is very important to prevent the migration of fine rive bed soils through the mattress layer. We use a 210g/m2 layer of Bidim to prevent soil movement. The Bidim is placed at all gabion and soil contact faces, behind, below and on the sides of the gabion structure. Overlapping 300mm where necessary.
