Solution

The operators of the the salmon farm detected a leak within their discharge channel during a routine maintenance check. In June 2021, Concrete Canvas Ltd visited the site to determine whether CC could be utilised to reline the channel. CC was subsequently specified and in spring 2022, CC8^® was specified and delivered to site in preperation for the shutdown period and work commencing.

Summary

The project was a great success and the entire works took 5 days to install.

Concrete Canvas Ltd took the opportunity to revisit the site in early April 2023 to see the channel after 1 year and speak with the site team. One of the additional benefits of lining the channel with Concrete Canvas^® is the reduced maintenance. Previously, cleaning the channel would take around 3 working days. In 2023, the cleaning time was reduced to 1.5 working days saving time and money for the client.
