Maintaining SUMO’s commitment to providing clients with unrivalled survey knowledge and a world-class survey experience, we are excited to reveal the addition of a range of new services in conjunction to SUMO’s current survey options:

  • Soil resistivity surveys

  • Self-potential (SP) surveys

  • Soil thermal resistivity surveys

  • Soil corrosivity testing

We are also expanding our capability in electromagnetic EM Surveys and Resistivity Imaging (ERT).

The SUMO Group is one of the UK's leading multi-disciplinary survey practices. With over 34 survey teams, 5 offices and nationwide survey coverage, there is no more guesswork above or below ground.


“Whilst there will be little change day to day for our clients, joining the SUMO Group allows us to provide a much wider range of services to them. It also gives us greater geographical coverage. Therefore, I am very excited at our future as part of the SUMO Group”

Marek Wajzer, Subsurface Geotechnical Principal Geophysicist


“Marek and Subsurface Geotechnical have built a fantastic reputation for specialist technical services. They have also provided outstanding customer loyalty. We are thrilled that they are now part of the SUMO family”
