The Portadam cofferdam system was originally developed in 1974 through a grant from the British Government. The purpose was to develop an environmentally friendly system that could be installed and removed quickly and efficiently to repair aging canals and waterways in an environmentally friendly condition. Leigh Flexible Structures (LFS) purchased the technology and transferred assets to their Canadian division to serve the North American market. In 1981, upon receipt of an order in the United States, LFS retained Walker Diving to install and remove the first system in North America. From 1981 to 1984, Walker Diving became the exclusive system installer for LFS’s Canadian division. In 1984, the owners of Walker Diving purchased the assets from LFS and operated the Portadam as a wholly-owned subsidiary of the family’s business. In 2004, Finger Lakes Capital Partners purchased the assets, investing in the Company to expand its operations into additional regions. More recently in 2010, Portadam began the development of its Above Ground Water Storage system, entering the Oil & Gas arena and has since completed numerous jobs across the country.  In 2014 Spring Capital Partners purchased the Company allowing it to establish a stronger market/brand presence in its existing markets as well as grow successfully into new regions and market verticals.
