Temporary Working Areas
In almost any construction project, working on weak or variable ground usually presents considerable challenges for soil stabilisation. But Tensar’s technology and know-how in ground stabilisation not only improves performance, but is proven to reduce costs and environmental impact of subgrade improvement too. Our innovative TriAx™ geogrids, with near uniform 360 degrees tensile stiffness for optimum performance, are designed to provide effective confinement of the granular fill. This results in a stiff mechanically stabilised layer, capable of controlling differential settlement, reducing road fill depths, capping weak deposits and increasing bearing capacity.

Working Platforms
Safety is critical when using mobile cranes, piling rigs and other heavy plant on construction sites – particularly over weak and variable ground. What’s needed is a safe working platform.
Tensar® TriAx Geogrids mechanically interlock with a well graded granular fill resulting in particle confinement which amongst other benefits increases the bearing capacity of the resulting Tensar mechanically stabilised layer or MSL. This allows heavier static loads from cranes or piling rigs to be carried or platform thicknesses to be reduced to cater for heavy rig loading.
Access Roads
Unpaved roads are a feature of construction sites around the world. But while they have to cope with extremely heavy loads, these working platforms often have to be sited on weak or variable ground. That’s where Tensar’s geogrids, incorporating clever working platform design – and in particular the innovative TriAx®– can help reduce costs by mechanically stabilising granular materials very efficiently. When compacted over the geogrid, the granular particles project through the triangular apertures and are mechanically confined. This interlock, combined with the grid’s near-uniform 360 degrees stiffness creates an efficient stiff composite layer for a working platform or unpaved road.
Temporary Structures
If a structure is needed as part of the site temporary works, such as a retaining wall or bridge abutment, practicality and economy typically take priority over aesthetics. The TR2 system has been designed to produce temporary structures which are straightforward to build, with face angles between 60° and vertical, for a lower cost compared with traditional reinforced concrete, as well as seeing use as permanent thrust relief structures.

Tensar Road Technology
Delays from roadworks; the pothole problem; new infrastructure vs budget cuts… Britain’s roads need value-engineered solutions more than ever. Tensar Road Technology is one such solution, bringing Joined-Up Thinking – in the form of revolutionary stabilisation geogrids and asphalt interlayers – to Britain’s highways. Tensar’s pavement optimisation and asphalt reinforcement solutions introduce a different kind of thinking to road design and repair, taking a longer term view to optimise performance and reduce initial and whole-life costs.
Earth Retaining Structures
Engineers who need to maximise the area of development for earth retaining walls and structures but are faced with difficult and varied terrain can choose from a wide range of options – reinforced concrete, gabions, crib walls, sheet piling and structural brickwork, and more. Increasingly, though, many are turning to Tensar Technology for a tailored solution which can meet aesthetic, budget and environmental need.

Embankment Support & Reinforcement
A key feature of many infrastructure projects, it’s vital that embankments are constructed with a firm and stable foundation. On weak and difficult soils this can present numerous challenges. However, Tensar has a number of ways around this problem avoiding the need for expensive excavation and replacement of the soft soil or piling.

Trackbed Stabilisation
For railways around the world, line speed restrictions and expensive and disruptive track maintenance are frequently caused by poor track geometry and misaligned rails. But Tensar’s rail track design technology has been proven to substantially reduce track maintenance, being the subject of extensive independent research and development and approved by Network Rail in the UK and National Rail Authorities worldwide.
