Soil displacement hammer

The earth rocket, also known as a ground rocket or ground displacement method, is a specialized tool used in civil engineering to create underground channels for laying pipes without the need for extensive excavation. This method is a crucial component of trenchless technologies and offers a quick, cost-effective solution for installing utility lines under obstacles such as roads, sidewalks, or existing infrastructure.

How does the soil displacement hammer work?

The earth rocket uses pneumatic power to propel itself through the ground. Using compressed air, the hammer inside the rocket strikes the rocket head, moving it forward in a straight line. This method creates a compact borehole through which pipes or cables can be subsequently pulled.


Economical and Environmentally Friendly: This method allows for cost-effective and eco-friendly installation of pipes in soils suitable for displacement.

Efficiency and Precision: With a forward speed of up to 15 meters per hour, the method is characterized by its speed and accuracy.

Minimal Entry Points: Only small starting pits are required to begin the propulsion, minimizing the impact on the ground.

Surface Integrity: The surface design is minimally affected by the construction work, as large excavations are eliminated.

Effective Soil Displacement: The technique supports the displacement of soil up to a diameter of 140 mm, suitable for pipes with an outer diameter of 125 mm.

Extended Installation Range: Installation lengths of up to 15 meters can be achieved with only a starting and ending pit.

Direct House Connections: House connections can be created easily and directly from the building without extensive excavation work.

Application areas

The earth rocket is ideal for smaller projects such as the replacement or installation of house connections, where quick and efficient work without major surface disruptions is required. It is commonly used in residential areas, for the installation of utility lines, or for the repair of connections beneath obstacles.
