Feb 18, 2022 The renovation of sewers and pipelines with "Lining with cured-in-place pipes" is an established standard construction method, starting with the planning process, through material production and installation, right up to checking the quality achieved. It is characterized by a wide range of applications and a high variance in the fabrication and application processes. This module teaches the essential basics in relation to the fabrication of the lining tube and its installation. After completing this module, you will have a sound knowledge of:
