Hydraulic Drilling (HDD)
Jetted drilling offers an innovative and efficient method for installing underground infrastructure. The jetting method is a directional drilling technique for horizontal drilling, also known as Horizontal Directional Drilling (HDD). It allows pipelines to be installed underground without the need to dig a trench. The boreholes can be several hundred meters long. The horizontal jet-drilling rig drills an underground channel and pulls one or more service lines or conduits through it as it retracts. This method enables fast and precise pipeline installation and is used for various infrastructure lines, such as power or telecommunications.
Advantages of HDD (Horizontal Directional Drilling):
