Nicospan Bank Protection at Barford Nicospan Bank Protection at Barford

The Rothen Group have recently installed a section of nicospan bank protection along the River Avon in Barford. The works were desperately needed as the clients rear garden was collapsing into the river. Due to the ecological sensitivity of The River Avon a soft bank protection was best in this case, whilst still providing a high quality and economical form of erosion control.

Soil was then used to back fill and the garden graded to create a stable edge to the garden.
