What Is the NX850?
The Tensar InterAx NX850 is manufactured from a coextruded composite polymer sheet that is punched and oriented to create a unique multi-aperture structure. The resulting grid features three distinct aperture geometries—hexagonal, trapezoidal, and triangular—along with an unimpeded suspended hexagon that allows aggregate to interlock from both sides.
The NX850 has rectangular ribs with a node thickness of 0.18 inches (4.5mm) and a continuous parallel rib pitch of 3.2 inches (80mm). It comes in a white/black/white color pattern for easy identification on the jobsite. This is the heavy-duty option in the InterAx line, designed for demanding applications.
Product Durability
The NX850 is engineered for long-term performance in buried applications. It offers 100% resistance to chemical degradation when subjected to aggressive environments, and 90% resistance to ultraviolet light and weathering. Once installed and covered with aggregate, the product is protected from UV exposure and will maintain its structural properties for decades.
The coextruded polymer construction provides consistent quality throughout the product. Each roll is tested in a GAI-LAP accredited laboratory and carries an Environmental Product Declaration (EPD) certified by UL Environment, verifying its environmental impact data.
Roll Sizes and Coverage
The NX850 comes in two roll sizes. Standard rolls measure 12.5 feet wide by 197 feet long, covering approximately 274 square yards at about 183 lbs per roll. Wide rolls measure 15 feet wide by 197 feet long, covering approximately 328 square yards at about 219 lbs per roll.

Comparing InterAx Products
The InterAx line includes three main products: the NX850, NX750, and NX650. All share the same multi-aperture geometry and coextruded construction, but differ in their rib profiles and intended applications. The NX850 is the heavy-duty option for demanding projects, while the NX750 suits moderate conditions and the NX650 handles lighter-duty applications.

Typical Projects
In Northern Ohio, the NX850 is commonly used for truck terminals, distribution centers, and heavy commercial parking lots where trailer traffic and loaded trucks are common. Municipal projects like bus depots, fire stations, and public works yards also benefit from the NX850's heavy-duty performance.
Industrial applications include manufacturing facilities, container yards, and equipment storage areas where forklifts and heavy machinery operate. The NX850 is also specified for temporary haul roads and working platforms during construction, providing a stable surface that holds up under repeated heavy equipment traffic.
