More successful stressing and testing completed at Hazelmere Dam – Jan 2017

At the spillway location at Hazelmere dam ultra-high capacity anchors (80 strands and up to 90m long) provide overall stability against sliding and overturning. The anchors also provide crucial support for the base of the world’s largest Piano Key Weir.   Despite the difficult access challenges anchors were successfully stressed and tested to permit early impoundment of water.
