BE-13 Renovation: Lining with Cured-In-Place Pipes - Final Work, Acceptance, Renovation Defects - v01

The renovation of sewers and pipelines with "Lining with cured-in-place pipes" is an assured standard construction method, starting with the planning process, through the production of materials, the installation, right up to checking the quality achieved. It is characterised by a wide range of applications and a high variance in the fabrication and application processes. This module teaches essential basics with regard to the required finishing work including the taking of samples, their testing for the acceptance of the rehabilitation performance and gives an overview of rehabilitation defects and their handling.

This module requires knowledge of the modules “Lining with cured-in-place pipes - Basics” and " - Processes” as a prerequisite.

After completion of this module, you will have a sound knowledge of:

  • procedures and process steps for connecting the CIPP liner to manholes and structures and lateral pipes;
  • quality influences during installation and
  • required tests for approving the professional installation of the CIPP liner.
