The paper presents a summary of waterproofing systems for tunnel construction, using the double shell method with the installation of a flexible waterproofing membrane. Many tunnels are still leaking, although a waterproofing membrane has been installed. The objective of this publication is to present details, connections between the overall concept and the sealing, not only related to the materials but also to installation procedures, with the aim to obtain a 100% watertight tunnel.
