Company history

Structural Soils has been providing award-winning, high-quality geotechnical and geoenvironmental ground investigation services to clients across the globe since 1964. When our managing director, Stephen Mackereth, started his 35-year journey at the business in the late 1980s, we employed 20 colleagues. Fast forward to 2024 and we are now a 250-strong workforce operating from seven locations across the country: Bristol, Castleford, Coventry, Glasgow, Hemel Hempstead, Tunbridge Wells and Wigan.

We are part of the RSK group, one of the UK’s leading environmental, engineering and technical services businesses. Working alongside the many businesses in the group enables our teams to provide bespoke, end-to-end solutions on wide-ranging projects.

Award-winning ground engineering

Structural Soils has won multiple ground engineering awards over the years. In 2024, we were shortlisted for four nominations: UK Geotechnical Team of the Year, Ground Investigation Specialist of the Year, Ground Investigation Project of the Year and Excellence in Outreach.
