Working Group meeting for committee ISO/TC 182 held over two days in Lisbon, Portugal – May 2017

The work of the committee ISO/TC 182/WG3 continues with the successful evaluation of 171 comments on the draft European standard for the testing of grouted anchors  ISO DIS 22477-5. In all some 325 comments were evaluated over two separate meetings, the first of which took place in London in early April 2017. The task of seeking resolution to the 325 comments was further complicated by the fact that there are three test types and three test methods associated with the test types. In addition, there are several member countries that adopt variations to the different test methods.  Despite this, there is no question that the meetings in both London and, more recently, in Lisbon where successful.

On the basis of the evaluation of comments, the document will be amended and resubmitted to the Working Group for further assessment over the coming months.

Dr Devon Mothersille delivers lecture in Austin, Texas – May 2017

Dr Devon Mothersille delivered a lecture entitled ‘An Introduction to High Capacity Anchors in Soils and Weak Rocks’ to the 38th Annual Short Course: Grouting Fundamentals & Current Practice, held at the University of Texas in Austin.

This forms part of an annual commitment to the short course and Dr Mothersille was honoured to share the stage with a host of high calibre international grouting experts. The subject matter was varied, covering many aspects of grouting technology, methods and applications in a variety of geological conditions.

Team BMW commissioned by CEATI to undertake complex anchor study – May 2017

A dream team comprising Dr Donald Bruce, Dr Devon Mothersille and Mr John Wolfhope (BMW) have been engaged by The Centre for Energy Advancement through Technological Innovation (CEATI) to undertake a study of world dam anchor practice in a bid to produce a Best Practice Guidance Manual for North American dams. CEATI based in Montreal, Canada is an influential trade organisation with a specific remit to improve technology that can facilitate further development and maintenance of dams which form an essential feature of the national energy enhancement infrastructure.

Dr Donald Bruce (Geosystems), Dr Devon Mothersille and Mr John Wolfhope (Freese & Nichols) recently met in Austin, Texas to develop forward strategies for the effective delivery of the project. This successful meeting has confirmed that many months of hard work lie ahead but this will undoubtedly result in a landmark study that will tremendously benefit the dam anchor industry worldwide.

Anchor technology seminar delivered to Lancuyen representative – May 2017

Senior Geotechnical design engineer from Chilean Foundation contractor Lancuyen, Mr Rafael Martinez, attended a specially organised two day ‘one-on-one’ seminar with Dr Devon Mothersille. This unusual initiative was requested by Lancuyen in order to accelerate their knowledge in ground anchor technology. During the intense two-day interactive knowledge sharing session, case histories were described which covered aspects of design, construction, testing and monitoring of ground anchors. New technologies such as AnchorTest were discussed and demonstrated together with detailed descriptions and evaluation of the Single Bore Multiple Anchor system. Lancuyen are currently considering the use of the SBMA system for a major slope stabilisation project in Chile and this was also discussed in detail.

Outstanding engineering consultant Ingerop South Africa (ISA) has purchased a licence to use the innovative software package AnchorTestTM ( ISA ( has an increasing portfolio of projects within, and outside South Africa, and will use the software package to enhance their design and site supervision capabilities on projects that utilise ground anchor technology.

Dr Devon Mothersille visits tendon manufacturer DECA s.r.l in Genoa, Italy – May 2017

Dr Devon Mothersille attended technical meetings and visited SBMA’s certified anchor tendon manufacturer DECA s.r.l. in Genoa, Italy. Over the years DECA has provided a high quality, reliable and professional service in providing geotechnical hardware on SBMA projects worldwide.

They have now expanded their portfolio beyond the supply of removable SBMA tendons to tendons for permanent anchor systems and monobar systems for both anchors and soil nails.  Substantial technical improvements have been implemented which allow DECA to deliver their high quality products in relatively short timescales.

Further to successful technical meetings DECA have agreed to act as agents for sale of the new innovative AnchorTest software licence which was developed, and is supported, by AnchorTest Ltd.
