ELECTRICALLY ISOLATED ANCHORAGES

This paper discusses the use of the Electrical Resistance Measurement (ERM) system designed to check the integrity of corrosion protection systems in ground anchors. A high resistance measurement confirms that the encapsulation is intact, a low resistance indicates that the sheath has been damaged. The measurements required are outlined and a case study from Zurich described. The development in Switzerland of a code defining corrosion protection and experience of its use so far are outlined. It is suggested that the opportunity for inspection of watertightness before handover has already led to better fabrication and construction practices. For the covering abstract see IRRD 898458.
