Stressing, cutting and capping progresses at Hazelmere dam – Sept 2017

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.
