Project W036:
Adhesion properties of short-liners

Posted 01. September 2011

Short lengths of selected repair systems were tested under external water pressure to examine their potential for sealing pipes against groundwater pressure. Comparative tensile-adhesion tests were undertaken using four short-liner systems on eleven different surfaces in order to determine the factors influencing performance and any need for surface preparation when refurbishing using short-liners. The systems predominantly exhibited good performance, and confirmed that repairs aimed at sealing against external water pressure…
