The new GRUNDOPIT PS40

GRUNDOPIT Mini fluid-assisted HDD rigs are applied when pipe installations up to 100 m length require the steerablity of the bore head, due to the required bore path. House connection service lines can also be installed by steering with the GRUNDOPIT bore rig to a small pit in front of the building, directly into the building or the cellar. This way you can close the gap between non-steerable soil displacement hammers and steerable HDD bore rigs. The production series has now been extended to include a further bore rig, specially developed for a quicker, near-surface production of house connections from the pavement – the GRUNDOPIT PS40.
