Senior executives from Ingerop France visit the Hazelmere Dam project – October 2017

Mr Yves Metz and Mr Christophe Blanc (Senior Executives from Ingerop France) visited the Hazelmere dam site in South Africa. Mr Duane Booyse (Resident Engineer on the dam project) and Dr Devon Mothersille (Specialist Anchor Consultant) delivered presentations to representatives from Ingerop France and Ingerop South Africa (ISA) which updated the visitors on the status of the dam construction with particular reference to the Piano Key Weir and the ultra-high capacity rock anchors. It is noteworthy that Dr Mothersille also pioneered the use of a drone to observe the progress of the dam construction and this video footage was also presented to the riveted audience.

After completing a detailed tour of the dam site the delegation enjoyed a meal at the famous south african golfer, Ernie Els’s restaurant (The Big Easy) at the Hilton Hotel in Durban.

Based on the discussions there is no doubt that the ties between Dr Mothersille and the Ingerop Group have strengthened and this collaboration will prevail on major infrastructure development projects in the future.

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.

Belated publication from CIRIA – July 2017

Back in December 2012 Dr Devon Mothersille presented a paper to an audience at the headquarters of the Construction Industry Research and Information Association (CIRIA) in London.  Interestingly, the paper, entitled, ‘Aged ground anchors and soil nails’ has only recently been published by CIRIA in the proceedings of the fifth conference on ‘Geotechnical Issues in Construction’ held on 3rd December 2012.

Amongst other things, the paper identifies the ground conditions that accentuate corrosion risk and uses case history evidence to illustrate severe corrosive degradation in anchor and soil nail heads.
