About Us


Geotron UK Ltd. was founded in 2002 by the collaboration of a UK based team with an environmental consultancy background and Geotron International B.V., an established Dutch drilling contractor operating internationally on environmental and geotechnical drilling programmes since 1989. The result was a UK-based independent company offering a range of technical site services to clients throughout the UK and the Republic of Ireland.

Operating initially with a single site crew, the company has grown year on year currently working with a team in excess of 30 site operatives, engineers, managers and support staff. We have continually added to our fleet of rigs, transport trucks and support vehicles ensuring we are always at the forefront of drilling technology, work efficiency and innovation.
