The Moretrench family regrets to announce the passing of ground freezing specialist Derek Maishman, P.E., on September 17, 2017. He was 88 years old. Derek came to Moretrench in 1976 following a distinguished career with UK-based Forakay, Ltd, where he ultimately served as Chief Engineer with responsibility for all of the company’s ground freezing operations in the UK, USA and Canada. At Moretrench, he was instrumental in establishing the company’s freezeWall subsidiary, since merged with the parent organization, and providing the technical expertise and experienced-based insight that formed the cornerstone of our present day operations.
Over the course of his career with Moretrench, Derek was responsible for the design and implementation of many notable projects in challenging subsurface conditions and shared his experience with the underground construction community through published papers, conference and seminar presentations, and as a contributing author to authoritative books. Although he retired from full-time employment in 1997, he continued to serve as a consultant to Moretrench into his 80s.
“Derek’s wealth of knowledge was critical to Moretrench’s early success in the ground freezing arena. He essentially laid the foundation for our work. It is a tribute to his considerable early contributions that we continue to be a leader in this field. Our condolences go out to his wife Enid at this difficult time.”
