Marking the launch of the 2020 LinerReport we are holding a free to attend 60-minute webinar on 14th April 2021.

This year’s IKT LinerReport presents the results from the evaluation of installed CIPP gravity sewer liners based on the testing of 2,600 samples taken post-installation. Our free webinar marking the launch of the 17th annual review of the performance of CIPP sewer liners is presented by Roland Waniek and Barbara Grunewald, two of the authors, and an international perspective about the Liner Report will be provided by Dec Downey from Trenchless Opportunities Ltd. It will cover:

  • Origins of the LinerReport – why it was requested by German sewer network owners
  • The requirements and how tests are undertaken by IKT’s Test Center for CIPP liners
  • Findings of the 2020 LinerReport
  • Trends observed over 17 years
  • An international perspective
  • Questions

Twice that day – for those far away

This webinar will be presented twice on 14th April 2021 at 9.00 – 10.30 BST and again at 16.00 – 17.30 BST. It is free to attend but you must pre-register to obtain the link. Registrations will be considered in the order in which they are received. The number of participants is limited. Early registration is therefore recommended.
