565 meters through dense forest, 40 meters beneath the surface: In Ehrenforst, we achieved our longest rock drill to date using the Double Rod System—a brand new milestone for our team.
Hard-to-access forest ground, solid rock formation of limestone and marl: In Mönchbusch, we successfully completed a technically challenging 330-meter HDD bore installing three product conduits.
530 meters beneath a busy main road: In Biotope, we pulled in three pressure-resistant HDPE pipes through demanding rock formations—overcoming a 27-meter elevation difference.
A main road, a distance of 652 meters, and drilling fluid losses in almost every drilling phase: In Aalbach, we prove that precision work is possible even under difficult conditions.
Without disrupting traffic, we completed a 230-meter HDD crossing under the A7 motorway. A compact yet technically challenging trenchless installation executed through limestone, marl, and claystone formations.
