TRENCHLESS PIPE ­INSTALLATION WITH COMPRESSED AIR

Technology that Delivers Below the Surface

Controlled soil displacement with compressed air enables trenchless pipe installation beneath existing surfaces. This creates a defined pipeline route without the need to open up roads, paving, paths or garden areas. Suitable for pipe diameters from DN 45 to DN 200.

Trenchless Pipe Installation with Compressed Air

ESSIG impact moles operate using the soil displacement method. Driven by compressed air and a percussion piston, the rocket is driven through the ground in a controlled manner. It displaces the soil without excavating it. Cables or pipes can be directly pulled into the resulting bore or installed subsequently. The result: a clean, fast and surface-friendly installation. This method of installing cables or pipes creates a low-effort alternative for power, gas, fiber optic and water lines.

THE ESSIG IMPACT MOLE
AT A GLANCE

Robust and Durable

Stable construction for maximum service life.

High Range

Bores up to 20m in length for efficient pipe installation.

Powerful in Operation

The stepped head penetrates even harder soils.

Flexibly Controllable

Easy switching between forward and reverse.

STRAIGHT-LINE CONSTRUCTION FOR LASTING STABILITY

The housing, piston and control mechanism are designed for durability and ease of maintenance. The precise coordination of components ensures consistent impact force and constant advance performance, even on long installation sections.

OUR HIGHLIGHTS
IN FUNCTION AND HANDLING

Precise Straight-Line Travel for Pinpoint Results

The construction of ESSIG impact moles ensures stable straight-line travel even over longer distances. This achieves high targeting accuracy, minimizing rework and significantly increasing efficiency on the construction site. The result: faster project completion and reliable results with every bore.

Interchangeable Drill Heads for Every Soil Type

Thanks to interchangeable drill heads, the impact mole can be optimally adapted to different soil hardnesses. This ensures maximum performance and efficiency in every area of application.

Reliable Manual Gear Shifting

Switching between forward and reverse gear is done simply by pulling the compressed air hose. After switching off and on again, the impact mole automatically restarts in forward gear. This analog control is particularly robust, easy to operate and significantly more fail-safe than electronic systems.
