Colus Successfully Reline 123m Culvert in Argoed, Wales

A 900mm diameter, 123m long culvert in Argoed, Flintshire was in need of relining and initially a UV CIPP installer was awarded the project. After an initial CCTV inspection it was clear the UV system was not suitable due to the number of bends within the culvert - up to 45 degrees in places.

Colus were tasked with finding a solution to successfully line the culvert and determined that a hot cure inversion liner would best suit the project although the amount of fall (40m) over the culverts length presented a number of risks.
