Land & Water Services were employed by British Waterways to install a Nicospan revetment system along approximately 1,000 meters of canal bank on both the South and North Stratford-on-Avon Canal.
The offside banks had been heavily eroded due to extensive boat ‘wash’ affecting the soft soils prevalent in this area, and by farm animals accessing the water from the banks. The system employed also negated the need for dredgings to be removed from site saving lorry movements and disposal costs.
The Nicospan and Verdatex geotextile systems were installed using sustainably sourced, 6ft and 8ft machine rounded posts. Land and Water’s own narrow beam pontoon with a 5t mounted excavator and hammer attachment was used to drive the posts.
Silts were then dredged from the canal to further open the navigable channel and placed behind the Nicospan. Coir rolls were then installed to the bank to provide a key to the new bank line.
