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.

Comments resolution meeting held at British Standards Institution, London, UK – 5th/6th APRIL 2017

As Chairman of Working Group 3 (part of the Technical Committee 182), Dr Devon Mothersille convened a meeting of pan European anchor experts to evaluate some 325 comments received on prEN ISO 22477-5 (Geotechnical investigation and testing – Testing of geotechnical structures – Part 5: Testing of grouted anchors). Over a two day period 12 attendees evaluated the comments and scrutinised the draft document, clause by clause. During a very productive and highly technical session considerable progress was made and this was due to the wealth of experience and technical expertise provided by the working group members.

The lunches for the delegates were sponsored by Single Bore Multiple Anchor Limited and the evening meal was sponsored by Dywidag Systems International. Many thanks are also due to Ms Jennifer Harris for her contributions with the administration and real-time editing and collating of information during the discussions.

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.

Outstanding performance by specialist foundation contractor Kasktaş AS – December 2016

Kasktaş A S continue their outstanding work by successfully executing the first phase of SBMA installations as part of the foundation support works for the Ferko Line project in Istanbul.
