The Dr. Sauer Group promotes the use of flexible membranes to providing dry underground spaces. We design Waterproofing System for All kinds of cut & cover and Tunnel Structures.

Since the beginning of the firm's existence, the Dr. Sauer Group has provided construction management and inspection services to complement the design and consulting work with experienced field supervision. The company’s group of field engineers and inspectors has helped to complete many successful tunnel projects throughout the world.

A crucial part of NATM tunneling (Sequential Excavation Method) as well as of other underground construction work is real time monitoring and documentation of the construction works.

Inspection and maintenance procedures for tunnels and underground structures are valuable tools, which help preserve the design life and keep these structures at a safe and operational level.

Many older tunnels today are either not used to their full potential or are not used at all due to their structural condition. These older tunnels can be widened in order to accommodate larger freight trains, trucks, light rail or to increase the traffic capacity and in the case of leaking tunnels and deteriorated tunnels can be rehabilitated creating a dry and safe environment.
