Tensar Corporation is a privately owned company headquartered in Atlanta, Georgia. The business was initially formed in 1983 as a joint venture between Gulf Canada Limited, Netlertewon Limited (now known as Tensar Group Limited in the United Kingdom) and Dr. Brian Mercer, the owner of Netlon Limited. Over his lifetime, Dr. Mercer, now deceased, invented the substantial majority of the process technologies used in the world today to manufacture integrally formed oriented polymeric grid and mesh structures. In 1988, senior executives of the joint venture in the U.S. purchased the business and managed and operated the entity through 2000. At that time the business was sold to a private equity investment firm, with the original Tensar executives then retiring and the ongoing Tensar management team retaining a minority interest. The Company was again sold in 2005 to another private equity firm located in Atlanta with management continuing to own a minority interest.
