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.

With the progress of science and technology in today's society, people's demand for various resources has increased, the exploitation and use of resources have increased, and the changeable and complex geological problems have gradually emerged frequently. Some of them are caused by water and soil loss, some are caused by equipment foundation settlement due to long-term use of equipment, and some are caused by the change of plant floor load. At this time, if we do not deal with it in time, it will affect the manufacturing accuracy of the equipment and the company's benefits. At this time, we are faced with the problem of "how to reinforce the foundation without affecting the normal operation of the equipment". Hengxiang Hongye has always been adhering to the concept of customer priority, using self-developed soil solidification technology to reset and lift the unstable settlement, and make the foundation more solid. Our solution is faster than the traditional repair method, which requires us to stop production, suspend business, move away from equipment and other methods for reinforcement In Hengxiang Hongye, all this is unnecessary. Our scheme and technology can complete the repair of the settlement parts in hours or days, without damaging the ground, causing little construction disturbance and zero pollution to the surrounding environment.
