Horizontal directional drilling through rocky ground in Vaux-sur-Sûre

Van den Berg was responsible for the horizontal directional drilling of 6 boreholes through rocky ground, crossing the path of various watercourses – a task that was completed smoothly thanks to the “AT Borectec MT18 ROCKDRILL” drilling rig. This drilling rig can perform directional drilling in soft ground formations, but can also be converted to operate in harder ground with the help of specialist rock tooling.

The company has taken the conscious decision to invest in drilling rigs of this type so that HDD can also be performed without difficulty in Wallonia. Due to the geography of this region, there is a greater likelihood of encountering hard ground formations here.

This type of drilling rig features the unique “rod-in-rod” system, where the drill rods are steered by the outermost rods. The mechanical drilling action at the drilling head is powered via the inner rods. That means progress can also be made during a steering operation, which is impossible if a standard drilling method (based on high-pressure injection of the drill flush) is employed.

In addition to this kind of specialist equipment, a thorough study of the nature and composition of the ground, in combination with the specific design of the drill path to be followed, is essential. BESIX Van den Berg has the necessary equipment and can also handle these studies, making it the perfect partner for your future projects.
