Sub Surface Celebrates 50 Years of Business
On 28th March 2022, Sub Surface proudly marked its 50th anniversary, having been founded by Clifford Marsden in 1972.
To celebrate this incredible milestone, the Sub Surface team enjoyed a well-deserved day out at the Flower Bowl in Preston. The celebration was full of energy and camaraderie as the team competed in a lively game of curling, followed by a delicious group meal. It was a perfect way to honour both our history and the people who’ve made it all possible.
Reflecting on this significant achievement, Chris Marsden, Managing Director, shared:
“Reaching 50 years in business is no small feat. It’s a testament to the hard work, resilience, and passion of our incredible team, both past and present. We’ve weathered economic storms, pushed the boundaries of geotechnical excellence, and grown stronger each year. I’m immensely proud of what we’ve accomplished together.”
Over the past five decades, Sub Surface has successfully navigated six recessions, an achievement that speaks volumes about the strength and stability of the company.
