The horizontal directional drilling technique 5. The horizontal directional drilling technique 5.1 General Since the early 1990‘s, there has been a close relationship between the development of this technique and ductile cast iron pipes. Back in 1993, Nöh [ .1] conducted some exploratory tests in which 0 m long DN 1 0 pipelines with positive locking joints were installed and were then withdrawn again from the bore to allow the surface stresses which had occurred to be assessed. The excellent results provided the justification for a 2 x DN 1 0 double culvert pipe about 200 metres long which was pulled in under the river Mosel in 199 at Kinheim, partly through rocky subsoil.
