GRUNDOSTEER
GUIDED ROD PUSHER
FULL TARGET CONTROL

STRIKINGLY SIMPLE, ROBUST AND RELIABLE

The GRUNDOSTEER combines proven trenchless pipe installation methods into one easy-to-use machine.

The locatable guiding head displaces the soil when the drill rods are driven forward similar to a soil displacement hammer but is tracked above ground with a locating device. Deviations from the route can be read on the locating device and corrected by rotating the drill rods. In the target pit, the guiding head is replaced by an expanding head and the borehole is enlarged during retraction. At the same time the attached pipe is pulled in. Drilling fluid is not required with guided rod pushing.

TRENCHLESS HOUSE CONNECTION IN NO TIME

In addition to short undercrossings, the GRUNDOSTEER is particularly well suited for quick and easy trenchless house connections. The compact unit can work from a pit to the building, or from the inside of the building through a core hole in the wall.

The alignment to the target is carried out with help of the GRUNDOSCOPE aiming frame. A simple, low-cost locating device is provided to determine the position of the guiding head during drilling. Thanks to the reliable steering principle and the easy directional correction, even less experienced operators can achieve successful house connections or short road crossings accurately using trenchless technology.
