Challenging ground conditions have necessitated the extensive waterproofing of anchor boreholes and this has resulted in delays to the overall construction programme at Hazelmere dam. Despite this, progress is being made, and at the time of writing all 83 anchor boreholes have been drilled and 40 of the scheduled 83 anchors have been stressed, tested and locked-off.

Deep Foundations magazine published by DFI (Deep Foundations Institute) enjoys an extensive worldwide readership and has recently published a five-page article featuring AnchorTest. The article includes the latest case history updates from around the globe where AnchorTest has been used for real-time testing and data management on challenging ground anchor projects. The September/October 2017 issue featuring AnchorTest can be viewed at http://dfi.dcatalog.com/v/September-October 2017/#page=65.
Geoserve Global Ltd will employ drone technology to assist with the inspection of anchor heads in circumstances where anchor heads are positioned in challenging locations. Please look out for future web postings that will show aerial photographs and video footage of the spillway at Hazelmere dam.
