Land-Based Near-Surface Geophysical Consultancy

Create better ground models through the use of geophysics and reduce the risk of unforeseen ground conditions and project overruns.

A geophysical survey can provide significant benefits to almost any site investigation. Data can be acquired extremely rapidly with high spatial resolution across most of the area of each site. The geophysical results can be used to locate complementary trial pits and bore holes in optimal locations, thereby reducing the risk of missing key aspects of the ground conditions. With the wealth of well-developed, proven geophysical techniques available, it is Best Practice to consider and, where appropriate, include a geophysical survey as part of the planning for almost any ground investigation.

If you are not a geophysical specialist, trying to get the best out of a geophysical survey can be a daunting task. If you get it wrong, you run the risk of wasting your money.

"CEGS have known of Reynolds International Ltd, previously Reynolds Geo-Sciences Ltd, since the mid-1990s and have utilised their services over the years for specific surveying in the former underground coal and iron ore fields of West Cumbria. As a lead consultant, we have used Reynolds International to successfully locate and define both the underground workings and the mine entries that pose a hazard to the built environment, especially shafts in the iron ore workings. Additionally, we have also enrolled on the CPD training courses that are organised by Professor John Reynolds and these provide an invaluable update to our professional skills. We will continue to use Reynolds International as our preferred specialist Geophysical consultancy because of the consistent high professional standards that are applied to every project."

"The British Embassy, Bucharest, has been working with Professor John Reynolds, of Reynolds International Ltd, since 2008 in order to ensure that the Embassy’s earthquake and emergency planning is up to date; and that all staff, dependents and the British community, for which the Embassy has a responsibility, are briefed on the causes, the preparations and the relevant actions in the event of an earthquake. Professors Reynolds’s knowledge, advice and guidance has been invaluable in ensuring that the embassy’s plan is as up to date and in an as workable format as possible. His knowledge is second to none and his guidance is clear concise and in an understandable format."

"The earthquake preparedness training course provided by Professor John M. Reynolds for BAT Romania’ employees during 3 days in February this year was a well designed and tailored course given the high seismic hazard area where Romania is located. The main aim of the course was to provide our employees with necessary information to help them to reduce their own vulnerability at work, in their out-of-work activities and in their family lives. I was very pleased with the results of the training and, most importantly, I have received very positive feedback from participants. I recommend this course for other commercial organizations in Romania or abroad."
