The TERRA-JACK TJA 125 stays in between an underground piercing tool and a small HDD pit launched machine. The directional rod pusher TERRA-JACK 125 is designed for directional house connections and road crossings in lengths up to 30 m (100 ft). The bore channel can be expanded up to 130 mm (5“). It is like a small HDD pit launched machine but does not require bentonite because it only displaces the ground like a mole. It is like an underground piercing tool, which users can steer. The TERRA-JACK is a directional Rod Pusher. It is the ideal machine for house connections underneath streets by narrow space conditions. The innovative machine works in easily displaceable ground. It can easily be lifted in the cellar.
