Open Trench Construction

A Central Technique in Sewer Construction

In open-trench construction, a key technique in sewer construction, the ground is first excavated where the pipeline route is planned. This creates a trench, with side walls secured by sheeting to prevent soil collapse. A stable bedding, typically made of sand or gravel, is then prepared for the optimal placement of the sewer system. Using an excavator, the pipes are carefully lowered from above and positioned on this foundation. Once the sewer has been successfully laid, the trench is backfilled in layers to ensure the stability of the newly installed structure.

The open construction method is used in various applications, such as new builds, house connections, renewal of existing systems, and in water extraction facilities. Companies like Steinzeug-Keramo offer a wide range of solutions for open-trench construction, providing the right choice for every need.
