Tensar Corporation is a privately owned company headquartered in Alpharetta, Georgia. The business was initially formed in 1983 as a joint venture between Gulf Canada Limited, Netlon Limited (now known as Tensar Group Limited in the United Kingdom) and Dr. Brian Mercer, the late owner of Netlon Limited. Over his lifetime, Dr. Mercer, invented the substantial majority of the process technologies used in the world today to manufacture integrally formed and 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.

1983   Tensar Corporation is formed as a Georgia corporation jointly owned by Gulf Canada Limited, Netlon Limited and Netlon Limited's majority shareholder. A freestanding organization is built from scratch in Atlanta to operate and manage the new business.

1984   A 175,000 sqare foot manufacturing facility is built in Morrow, Georgia (just south of Atlanta) based on a significant scale up and re-engineering of prototype process technology previously developed and practiced by Netlon Limited in the United Kingdom. The facility is commissioned in the third quarter, ahead of schedule and below budget, and immediately achieves throughput rates for Tensar® uniaxial and biaxial geogrid products which had been set as 10-year goals.

T. Boone Pickens of Mesa Petroleum initiates a hostile takeover of Gulf Oil Corporation, the parent company of Gulf Canada. Rather than submit to the hostile takeover, Gulf Oil Corporation subsequently sells the business to a "white knight," Standard Oil of California (which adopts the name Chevron Corporation at the time of the transaction).

1985   To pay down debt associated with the acquisition of Gulf Oil Corporation, Chevron begins to sell off various assets. Consequently, Chevron sells a 60% interest in Gulf Canada Limited, a part owner of Tensar, to the Reichmann family through it's holding company, Olympia & York. After its sale to Olympia & York, Gulf Canada narrows its strategic focus to concentrate on petroleum exploration and production. As a result, it begins to seek the divestiture of its investment in Tensar.

1986   Novel construction practices are developed by the Company using Tensar foundation improvement systems and earth retention systems to "piggyback" a new municipal solid waste landfill on top of an existing, full-to-capacity landfill on Long Island, New York. This pioneering achievement redefines land use and regulatory options for meeting future municipal solid waste containment needs in the United States.

1987   The novel practice of using Tensar earth retention systems and foundation improvement systems in large scale landform contour regrading is pioneered by the Company at the award-winning Ridgegate project in La Jolla, California. This extremely profitable method of transforming marginal properties into prime real estate is repeated in later years at Marbella, Ritter Ranch, Spanish Hills and several other marquee developments.

1988   Tensar Corporation is purchased from Gulf Canada Limited and Netlon Limited by the joint venture's U.S. senior management team. Business practices, particularly those relating to technology development, market development and employee performance incentives, are aggressively redefined to develop broader, longer term growth opportunities.

Landform contour regrading practices are further enhanced to architecturally customize very sophisticated site improvements at Disney World's Typhoon Lagoon attraction. This extremely economical method for precision "sculpting" of large land masses to fully satisfy both the aesthetic and structural objectives of a very creative and very demanding owner is repeated in later years at Disney World's Blizzard Beach and Animal Kingdom attractions and several other marquee developments.

1989   Tensar Earth Technologies, Inc. is formed as a subsidiary
of Tensar Corporation with responsibility for earthwork construction markets with greater engineering service needs. An in-house experienced and specialized engineering department is available to assist customers on request with engineering designs and initial construction assistance.

At the same time, Tensar Polytechnologies, Inc. is formed as a subsidiary of Tensar Corporation with responsibility for supplying specialty products and applications to the building materials and industrial netting markets.

1990   In litigation with a European competitor, a challenge to the U.S. Tensar "Method" patent is pushed through a United States Federal District Court, a Federal Appeals Court and the United States Supreme Court. The patent is found to be valid, enforceable and infringed. In the end, Tensar Corporation collects substantial monetary damages from the infringer.

1992   The United States Army Corps of Engineers independently and privately conducts extensive, full-scale testing of Tensar structural geogrids and their various competitors, including both conventional construction materials and practices and competitive polymeric materials. The government finds that Tensar products dramatically outperformed all competitive alternatives, and that several competitive polymeric materials provided little or no improvement over unreinforced structures.

1993   Numerous novel practices are pioneered by the Company in landfill construction in the United States, which gives owner/operators a more economical means to comply with new federal environmental protection regulations ("Subtitle D") on sites compromised by topography, soil conditions, setback requirements and the like – e.g., structural support of steepened inboard slopes on perimeter containment berms, stabilization of protective earth covers over membrane lining systems on steeply sloped surfaces, aesthetic outboard retaining walls functioning as perimeter containment berms in urban areas, etc. These many back-to-back "firsts" subsequently become standard practice in the industry in the United States and elsewhere.

1994   A Tensar foundation improvement system is used to construct a minimum footprint, low environmental impact haul road to access petroleum resources through approximately 100 miles of rain forest in Ecuador.

1997   Reciprocating die "Rical" technology is acquired and successfully commissioned by the Company at its Morrow, Georgia facility, allowing it to produce high quality, lower cost square-aperture lightweight-oriented nets primarily for the original equipment manufacturer (OEM) product fabrication and erosion control markets.

2000   The equity interests of the Company are purchased by a financial consortium led by KRG Capital Partners in association with AIG Global Investment Corporation, with Company management retaining a minority interest.

2002   Tensar Corporation purchases Geopier Foundation Company.

Tensar Corporation is named one of the 50 most innovative small businesses in the U.S. by Inc Magazine.

2004   Tensar Corporation purchases North American Green.

2005   The equity interests of the Company are purchased by Arcapita Inc., with management continuing to own a minority interest.

Geopier Foundation Company introduces its new and proprietary Impact™ pier technology in the U.S.

2006   Tensar Corporation acquires Tensar Group Limited in the U.K., combining that business with Tensar Earth Technologies in the U.S. to form the global group of companies known as Tensar International Corporation with manufacturing facilities and technology centers in the U.S., United Kingdom and China.

2007   A major plant and equipment expansion is completed in the Morrow, Georgia facility.

A revolutionary new geogrid for stabilization applications, TriAx is launched by the company into the European markets.

2009   TriAx geogrid is launched in the Americas and quickly replaced Tensar Biaxial geogrids as the Tensar Corporation market leading products in the Americas.

2010   Phil Egan retired as President and CEO. To be replaced by Don Meltzer.

2011   The head office relocated to Alpharetta combining the Corporate Office and Tensar International Corporation into single modern office suites.

The North American Green subsidiary business was fully integrated into the Tensar International businesss combining sales and customer services.

The company acquired Mulch and Seed Innovations LLC to add to the portfolio of erosion protection solutions.

After 25 years of successful collaborations, Tensar International Corporation and Contech Construction Products Inc. mutually agreed that Tensar would take on distribution responsibility in the United States.

2012   Strategically important sale of Tensar Polytechnologies business for lightweight extruded net to Conwed
