Overview

The TensarTech TR2 system has been developed for the construction of temporary earth retaining structures which are quick and straightforward to build, with face angles between 60° and vertical, as well as for use as permanent hidden thrust relief structures. For temporary and hidden applications, aesthetics takes an acceptably lower priority than achieving lower construction costs compared to other reinforced soil systems.

System Components

The TensarTech TR2 system is comprised of steel mesh face units - lined with durable, heavy duty geotextile - securely connected to Tensar uniaxial geogrid soil reinforcement via Tensar’s highly effective bodkin connection joint. There is no requirement for an external face support or formwork, owing to the rigid steel mesh face being braced internally and held in place by the geogrid and fill material during construction.

Single Source Solution 

The components of the TensarTech TR2 system have been specifically designed to work together for optimum efficiency and performance. Steel mesh panels, geotextile liner, polymer bodkin connectors, and Tensar uniaxial geogrids work together to form a  reinforced soil wall system that meets the design needs.  Tensar’s experienced engineers, using our sophisticated TensarSoil software, can provide everything from free application suggestions to a full design and supply service.

Temporary Walls and Bridge Abutments

Projects often require the construction of temporary earth retaining structures, either to support staged embankment construction to enable traffic to flow through the works, or for load bearing bridge abutments for haul roads or temporary rail crossings. TensarTech TR2 wall systems have been proven for all types of temporary earth retaining wall applications on major projects across the globe.

No Fuss - No Risk Construction – Simple and Rapid

Contractors appreciate the constructability of TensarTech TR2 systems. The construction requires no heavy lifting equipment and construction is straightforward, and placement of the geogrid reinforcement and connection to the steel mesh face is simple and quick using polymer bodkins. The rest is straightforward earthworks. Typically, no structural foundation is necessary, mobilisation costs are minimal and staged construction is easily accommodated. Tensar can provide detailed construction drawings as part of the design and supply service, and site assistance is available when needed. No fuss, simple and quick.

Hidden Thrust Relief

The TensarTech TR2 system has been used for thrust relief of historic masonry wing walls in bridgework refurbishment, as well as for protection of Victorian-era masonry retaining walls. In new construction, buried TensarTech TR2 structures have been constructed to relieve earth pressure on basement walls, culverts and piled bridge abutments. With a low building cost, and with a 120-year design life, they are ideal for these hidden permanent applications.

Independent Assessment and Approval

Highway Authorities Product Approval Scheme (HAPAS) was set up in 1995 to recognise innovative products and systems used in UK highway works. It leads to a Certificate or Report which provides highway engineers with product performance, design and installation data invaluable to the product choice and project planning processes. The TensarTech TR2 System and selected Tensar uniaxial geogrids have been certified by the British Board of Agrément (BBA) and awarded HAPAS approval. The BBA certifies that Tensar geogrids and the TensarTech TR2 system have been evaluated independently as fit for their intended use.

The Strength Behind the TensarTech TR2 System: Tensar Uniaxial Geogrid

Tensar uniaxial geogrids are manufactured from select grades of HDPE resins that are highly oriented and resist deformation when subjected to even high tensile loads for long periods of time. Their open aperture structure interlocks with natural fill materials, making them ideal for reinforced soil applications. The high pH associated with proximity to concrete or some recycled fill materials does not affect the durability and functionality of HDPE geogrid reinforcement during a life of up to 120 years.
