With the HDD drilling technique (Horizontal Direction Drilling) objects can easily be crossed over bigger distances without excavation. A small excavation pit at the start and end of the drilling is sufficient to execute the drilling.
With the HDD technology, pipes of HDPE, steel, cast iron, GRP and GRE can be installed which serve as a casing or medium-carrying pipe for, among other things, drinking water, waste water, process water, low pressure gas, high pressure gas, biogas, district heating, oil , fiber optic, medium and high voltage cables.
HDD – drilling in the past was mainly used for crossing rivers, canals, railways and highways. Today, this technique is increasingly used for crossing nature-sensitive areas, existing cables and pipes, rows of trees and in industrial areas and in urban areas.
