The last time old friends and colleagues Mr Gabriel Ige and Dr Devon Mothersille met was in 1985 during the graduation ceremony for their first degrees in Civil and Structural Engineering at the university of Bradford in West Yorkshire (UK). 34 years on Gabriel Ige is the Regional Planning Manager for Building at Vinci Construction and after establishing contact via Linkedin, he invited Dr Mothersille to a lunchtime meeting at Vinci Construction’s UK headquarters in Watford.
The useful discussions identified several areas of common professional interest and confirmed that through Vinci offices across the world there is realistic potential that Dr Mothersille’s specialist geotechnical expertise could be utilized by the organisation.

In 1979 the renowned Grouting Fundamentals & Current Practice short course was founded in the USA, and since then has provided unique professional training and education to thousands of grouting professionals worldwide. In response to industry interest, the course organisers are pleased to now offer this exceptional training opportunity in Munich, Germany. The 1st European course edition includes a faculty of 15 experts from 10 countries, providing exceptional breadth and expertise concerning grouting fundamentals and international best practices.
This unique 4-day professional training program covers pressure grouting as a method to improve geotechnical properties of soils and rock masses, with special focus on mechanisms, theories, and practical applications of grouting to ground densification and strengthening, permeability reduction and groundwater cutoffs. The curriculum has been developed specifically for Owners, Regulators, Consultants and Contractors having interest in the applications of pressure grouting to a broad array of geo-structural construction and remediation techniques.
Major course topics include:
- grout rheology
- cementitious and chemical grouting procedures
- overburden and rock drilling methods
- optimizing grouting during construction
- jet grouting
- deep soil mixing
- composite seepage barriers
- compaction grouting
- rock anchors and SBMA design
- compensation grouting
- permeation grouting
- GIN and RTGC in rock grouting
- amenability theory
- pre-excavation grouting for rock tunnels
- concrete repair
The course also includes a half-day “hands-on” field demonstration focusing on grouting materials, procedures and equipment.
Following the successful delivery of a lecture at a British Geotechnical Association meeting on the previous day, Dr Mothersille enjoyed an evening of discussions on research opportunities with Emeritus Professor of Transport Infrastructure Engineering at University College London, Tony Swain.

On Wednesday 15th May 2019 Dr Devon Mothersille delivered a presentation at the ICE headquarters at One Great George Street, London on behalf of the British Geotechnical Association. The presentation was entitled ‘Ground Anchors: An Overview of Grouted Anchor Technology with Particular Reference to UK Practice’.
The event was well attended and was also streamed live so that interested members from the wider engineering community who were unable to attend could still access the information shared. The evening started with a tea/coffee reception in the ICE Brasserie followed by the lecture, a Q & A session and then a social gathering in the ICE Café bar sponsored by Geoserve Global Ltd.
The lecture briefly looked at the effects of the introduction of Eurocodes on UK grouted anchor practice, clarified the essential features of maintenance inspections and service behaviour monitoring and described a case history where the world’s largest capacity cyclically loaded anchors where implemented to support overall stability in a concrete gravity dam.
Enjoy some photographs from the event.

Followers of this blog may recall that in December 2018, Dr Devon Mothersille visited Bauer (Egypt) at their offices in Cairo to negotiate a deal involving partnership between SBMA Ltd and Bauer (Egypt). We are delighted to announce that the deal is now secured and Bauer (Egypt) are exclusive licensees for SBMA technology in Egypt. Together with SBMA’s certified tendon manufacturer DECA SRL (based in Italy), we have big plans for the region and look forward to implementing the technology on projects in the very near future.

During meetings with Bauer UAE in Abu Dhabi and attendance at the DFI conference in Dubai, Dr Devon Mothersille took the opportunity to visit one of Bauer’s impressive construction sites. The project, commissioned by the Dubai Municipality, involved the development of a Deep Tunnel Stormwater System in Dubai’s Jebel Ali district. The deep tunnel stormwater system is intended to collect groundwater and stormwater runoff from an area of about 420 square kilometres and convey the captured flows to the sea. Bauer UAE was engaged by main contractor Archirodon Group N.V. and is responsible for the construction of the Main Terminal Pumping Station and Sea outfall which involves major diaphragm wall construction and ground anchor works.
The construction comprised two intersecting circular shafts of 64m and 45m diameter, 60m and 35m deep, respectively.

On the 24th and 25th April 2019 the Middle East Division of the Deep Foundation Institute held a conference that covered a variety of case histories and topics under the theme Geotechnical Engineering for Delivering Sustainable, Cost Effective Projects. The conference was hosted by the Roads and Transport Authority (RTA) at their headquarters in Dubai.
Forming part of a team with Bauer UAE’s Regional Geotechnical Design Manager, Mr Bora Okumusoglu, Dr Devon Mothersille delivered a presentation entitled ‘Implementation of High Capacity and Removable Ground Anchors for Support of Deep Excavation in the United Arab Emirates’. Mr Okumusolglu delivered a separate presentation entitled ‘Unsymmetrical Twin Shaft Retention System for Stormwater Terminal Pumping Station in Dubai’.
The conference also benefited tremendously from a number of keynote lectures including one from Dr Mothersille’s research colleague from the University of Bradford (UK), Dr Abdussamie Mohammed Haimoni (Senior Manager at the RTA) who delivered the opening address.
This conference was enjoyable and highly informative and left the delegates in no doubt that the Middle East is embracing innovation, sustainability and a high standard of technical excellence in solving complex geotechnical problems.
Enjoy photographs taken from the conference.
