Following the installation of a new 350mm diameter rising main at the Knostrop Sludge Treatment Works (STW) in Leeds, the client required a weed suppression layer below the pipes to prevent the need for future maintenance. These measures would also eliminate risks of damage to the pipes during maintenance.

The client specified Concrete Canvas® (CC) without the need to consider alternatives. The contractor, JN Bentley also backed the material’s specification following their experience of using CC on multiple successful projects in the past.

CC was installed with considerable time and cost savings and without the risk of rebound or damage to the pipeline associated with sprayed or poured concrete methods.
