By developing Pipe Express® Herrenknecht AG has set new standards for installing pipelines. With this system, no groundwater lowering is necessary and, in comparison with the open construction method, routes can be considerably narrower. This has a positive effect on construction costs. Because it is highly ecological and cost-efficient procedure, the development of this new system is being subsidized by the German Environment Ministry.
The Pipe Express® technology combines the advantages of trenchless installations and open-cut solutions. Pipe Express® can be used in any kind of soft to medium formations. However, the technology exhibits its major benefits mainly in unstable soils such as sand and gravel as well as in soil with water-bearing layers. As the pipeline is quickly installed in one step and fewer construction machines are required, emissions of exhaust gases and noise can be decreased by using Pipe Express®considerably.
