Embankments and retaining walls built with TensarTech systems are used to maximise residential development space and have attractive and natural finishes, helping to create pleasant surroundings for new homes. Tensar’s wall and slope systems can be used with non-standard fill, including selected site-won material.
TensarTech systems can also be used to build wing walls and load-bearing bridge abutments for link roads and associated development infrastructure. They are BBA HAPAS certified for use on structures with a 120-year design life.
The benefits:
- Fast construction
- Simple to build
- Attractive and natural finishes
Providing safe working areas is critical when building new homes, particularly on weak and variable ground. Tensar TriAx geogrids improve the performance of granular fill used for working platforms, increasing bearing capacity so the ground can support heavy loads from cranes, piling rigs and other construction plant. Efficient load-spread designs, backed by performance testing, deliver thinner platforms, shortening construction times and reducing materials use, compared with conventional designs.
The benefits:
- Increased bearing capacity
- Reduced layer thickness
- Saving time and money
Tensar TriAx geogrids are used to mechanically stabilise the aggregate layers of unsurfaced access roads, improving the performance of granular materials and enabling them to support heavy construction traffic, particularly over weak and variable ground. This means fewer material imports, saving time and money.
Once construction has finished, these temporary roads can form the foundation of permanent roads (including highways adopted under Section 38 agreements) and car parking areas, speeding up this important element of residential development, ensuring projects are completed on time and as economically as possible.
The benefits:
- Enabling temporary road construction over weak ground
- Reducing the need to import fill, saving time and money
- Delivering foundations for permanent roads
Building homes inevitably involves construction of new local and major roads and re-routing of existing links. Suitable for any ground conditions, Tensar’s Spectra Pavement Optimisation System uses the proven capability of Tensar TriAx geogrids to create a mechanically stabilised aggregate layer contributing to, and improving, overall performance of access roads, car parks and highways adopted by local authorities under Section 38 agreements.
The benefits:
- Reduced pavement costs
- Increased pavement life
- Lower whole-life costs
TensarTech EcoCrib delivers steep retaining walls to maximise development space and as part of residential landscaping schemes. EcoCrib is a 100% recycled polymer retaining wall that can use site-won granular and recycled fill, reducing materials costs and improving a development’s green credentials.
The aesthetically-pleasing alternative to timber or concrete crib walls is resistant to ultraviolet light and will not rot or be affected by water or fungus infestation. EcoCrib facing units are BBA HAPAS certified for use on structures with a 120-year design life.
The benefits:
- Helping maximise development space
- Enabling use of site-won material
- 100% recycled and 100% recyclable, made from waste polymer
TensarTech GreenSlope is used to build steep (45-70°), naturally-vegetated slopes for residential developments, including bunds to minimise the noise and visual impact on new homes and their surroundings. GreenSlope’s modular and durable steel facing units allow vegetation to establish and enables the re-use of site-won fill to reduce materials costs and cut construction time.
The benefits:
- Modular, durable facing units
- Enabling re-use of site won materials
- Reducing construction time and cost
TensarTech TW1 modular block wall systems are used to create retaining walls and attractive landscaping features for residential developments, quickly and economically. Strong and durable, with a design life of 120 years, walls require minimal maintenance and can be built without cranes or the need for temporary propping.
The benefits:
- Proven alternative to traditional solutions
- Construction time and cost savings
- Strong, durable, minimal maintenance
Tensar TriAx geogrid creates stiff mechanically stabilised layers through ‘interlocking’: as load is applied, granular particles partially penetrate and project through the geogrid’s apertures, resulting in their confinement and lateral restraint and increasing stiffness and reducing deformation of aggregates. TriAx is used for a range of applications on housebuilding projects, from temporary and permanent access roads to working platforms.
The benefits:
- Improving the performance and bearing capacity of granular layers
- Reducing construction time and cost
- Suitable for temporary and permanent access roads and working platforms
Working platforms often support heavy loads over weak or variable ground. TriAx geogrids improve the performance of granular materials, saving housebuilders time and money. Additional benefits include increased bearing capacity and reduced layer thickness.

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.
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.
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 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.
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.
Key benefits include:
- Save up to 50% - 75% on traditional reinforced concrete structures
- Rapid to construct and can cut construction times by half
- Use of site won materials can reduce costly imported fill
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.
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.
