Short Term Testing & QA of CIPP Liners

Title: Short Term Testing and QA of CIPP Liners

When a new pipe is installed quality assurance will have been applied throughout the manufacturing, storage and delivery process, and it is possible to finally reject any defective sections as they are laid in the trench. With trenchless pipe rehabilitation the ‘new pipe’ is created out of sight by a curing process within the host pipe on the day of installation, and is usually expected to have a life span as long as a new pipe. Installation has been described as ‘conducting complex chemistry in the bottom of a ditch’! This webinar will consider the development of QA for CIPP linings of gravity sewers, in particular how short term mechanical tests on samples taken from installed liners are used to assess the success of installation and curing.

Speakers: Ian Naismith, PhD, Senior Research Fellow Project Manager, UK & International and Dieter Homann, Director of Material Testing at IKT.
