Tensar International Limited

What Tensar International Limited does

Tensar International Limited, founded in 1959 and headquartered in Blackburn, United Kingdom, is the original inventor of geogrid technology and a global manufacturer of ground stabilization and soil reinforcement solutions. The company operates as a division of Commercial Metals Company (CMC, NYSE: CMC) following CMC's 2022 acquisition of Tensar Corporation. Tensar's core products are oriented HDPE and polypropylene geogrids (InterAx, TriAx, H-Series, Uniaxial, Biaxial) that mechanically interlock with aggregate to form Mechanically Stabilised Layers (MSL) for roads, working platforms, rail trackbeds, retaining walls, and embankments. Beyond geogrids, the portfolio includes TensarTech modular wall systems, Glasstex asphalt reinforcement, Basetex geotextiles, and Stratum cellular foundation mattresses, supported by the free Tensar+ cloud-based design software.

Tensar serves a horizontal civil engineering customer base across nine primary verticals — roads & highways, working platforms, rail, renewables (wind, solar, BESS, hydrogen), reinforced soil walls & slopes, foundation & embankment support, commercial & industrial, housing & residential, and airports — with documented enterprise customers including VINCI Construction UK, Morgan Sindall, Murphy Group, and the ESB / Bord na Móna joint venture. The company employs over 650 people across 15 countries with manufacturing in the USA (Morrow, GA), UK (Blackburn), and China (Wuhan), supplemented by hundreds of distribution partners. Tensar holds 110+ patents and reports 2M+ ESALs of testing data accumulated over five decades.

The business model is predominantly hardware sales of geogrid products, complemented by free professional design support services that act as a specification and lead-generation channel, and a freemium cloud software offering (Tensar+) for design optimization. Pricing on products is quote-based rather than list-published; Tensar+ is provided at no cost under a royalty-free license to capture engineers early in the specification cycle. Tensar differentiates through documented project outcomes — up to 70% aggregate reduction, up to 65% carbon emissions savings, up to 50% construction time savings, and up to 120-year design life — which are central to its value proposition in a market increasingly driven by sustainability mandates.

Core offering

Tensar manufactures and sells proprietary polymer geogrids (InterAx, H-Series, TriAx, Uniaxial, Biaxial) for ground stabilisation and soil reinforcement, supported by TensarTech wall and slope systems, Glasstex asphalt reinforcement products, Basetex geotextiles, and the Stratum cellular foundation mattress. Customers are civil engineering contractors, infrastructure developers and design engineers who specify Tensar products for roads, working platforms, rail trackbeds, retaining walls, foundations and renewable energy projects, with the free Tensar+ cloud software providing design and specification support.

Product overview

Tensar International Limited is a division of CMC and a world-leading manufacturer of geogrid technology for ground stabilisation and soil reinforcement solutions. The product portfolio consists of multiple geogrid product lines (InterAx NX, H-Series HX, TriAx TX, Uniaxial RE, Biaxial SS), complementary wall and slope systems (TensarTech TW1/TW3/TR2, RockWall, Mesa, SierraScape, NaturalGreen, GreenSlope, EcoCrib), asphalt reinforcement products (HX-AE, Glasstex, AX5-GN, GlasstexPatch), foundation and embankment systems (Basetex, Stratum), and the Tensar+ cloud-based design software. The geogrids serve as the core technology, with the Tensar+ software providing design support for implementing these solutions across roads, pavements, working platforms, retaining walls, slopes, foundations, and rail trackbed applications.
