Overview

When space allows, steep vegetated slopes offer an attractive and lower cost option than vertical earth retaining walls. The TensarTech GreenSlope System is used for construction of stable soil embankments with a slope face angle up to 70°. Cost savings of up to 70% can be achieved, compared to a conventional concrete retaining wall.

System Components

The stability of the TensarTech GreenSlope structure is provided by reinforcing the embankment with Tensar uniaxial geogrids placed horizontally within the fill. The slope face is supported by durable steel mesh units positively secured to the geogrid reinforcement using Tensar’s high strength bodkin connection. The facing units are lined during installation with an appropriate erosion mat, to help establish the chosen vegetative cover to the slope face.

Single Source Solution 

The components of the TensarTech GreenSlope system have been specifically designed to work together for optimum efficiency and performance. High quality welded mesh panels, polymer bodkins for high strength connection, face liner and Tensar uniaxial geogrids work together to form a reinforced soil slope system that meets or exceeds the industry standard.  Tensar’s experienced engineers, using our sophisticated TensarSoil software, can provide everything from free application suggestions to a full design and supply service.

Proven Solution for Steep Embankment Slopes

The rapid, economical construction – often requiring no specialist construction skills – delivers the cost effectiveness and versatility of the TensarTech GreenSlope System and offers clients, specifiers and contractors many advantages over other earth retaining construction methods, such as a reinforced concrete, gabion or crib walls. These advantages include the option to use site-won or recycled granular fill materials. The system also offers high tolerance of differential settlement, high resistance to earthquake loading and a low bearing pressure which may avoid expensive foundation treatment . Lastly, the system is durable, requiring little or no maintenance and offers attractive, natural vegetation.

Good Advice – Naturally

Selecting suitable plant or grass varieties for a specific project is essential. The advice of a local horticulturalist can ensure that varieties are chosen that are appropriate to the climate, location, slope angle and aspect of a particular structure. In addition, they can advise on establishment procedures and any irrigation requirements in more arid regions. The type and layer thickness of topsoil or alternative growing medium can be specified and accommodated in the design.

Structural and Landscape Options

 Whether you’re increasing usable land or improving property value, the TensarTech GreenSlope systems can solve your most challenging earth retaining requirements. From building large load bearing embankments to small, tiered garden installations, TensarTech GreenSlope can blend its slope stabilisation effortlessly with the natural surroundings of any site. 

The Strength Behind the TensarTech GreenSlope System: Tensar Uniaxial Geogrid

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

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. Selected Tensar uniaxial geogrids have been certified by the British Board of Agrément (BBA) and awarded HAPAS approval. The BBA certifies that Tensar geogrids have been evaluated independently as fit for their intended use.
