Microtunnelling is a pinpoint method of installing a pipe. Most microtunnelling contractors are aiming for a result which would see a pipe installed +/-10mm of design line and grade. However the accuracy of this line can be greatly affected by an accumulation of tolerance errors – sometimes referred to as tolerance stack. Any microtunnelling installation begins with a survey of […]

Question answered by Charles Stockton, Managing Director of Stockton Drilling Services. HDD expert Charles Stockton says: Firstly, drilling risks should always be minimised by undertaking adequate geotechnical surveys prior to drilling commencing. The contractor then needs to maintain thorough drilling records, which can be used to continually refine the geological model and assist in decision making during construction. Too often geotechnical information […]
