JB Site Investigations joined RSK in 2016 and has evolved into a key part of the group’s extensive ground investigation offering. JB is experienced in delivering cable percussion and rotary drilling, window and dynamic sampling, water-well construction and geothermal drilling throughout the UK. The company has been trading since 1975; its location in Berwick-upon-Tweed, UK, expands RSK’s geographical coverage to give RSK an additional presence in the north of the UK on the border of England and Scotland. Following the acquisition of JB Site Investigations, RSK is now the largest site investigation provider in the UK.
