Visser & Smit Hanab masters the technique of horizontal directional drilling (HDD) like no other party and carries out this drilling all over the world under rivers, railway lines and all kinds of obstacles. We were at the forefront of this development, which prevents costly open excavations. We work with a computer-controlled drilling rig (rig) that pulls the cable, casing pipe or pipeline through the ground. With our own team of designers, geologists, engineers, drillers and good equipment, we are ready for any drilling.
