Overview

When there is insufficient space for a naturally stable slope an embankment footprint can be reduced by steepening the batter or switching to a retaining wall. Where an attractive, completely natural look is preferred, or in environmentally sensitive areas, TensarTech NaturalGreen is a versatile solution for steepened slope face angles up to 45˚. The system easily lends itself to the repair of slip failures, in addition to the formation of new steep slopes, and construction costs are considerably lower than retaining wall options.

System Components

Stability of the steep slope is provided by the inclusion of horizontal layers of Tensar uniaxial geogrid reinforcement at specific vertical spacing within the embankment fill. In most instances an erosion protection mat is included on the slope face to aid the establishment of appropriate vegetation and protect from heavy rainfall. Construction of TensarTech NaturalGreen is essentially an earthworks operation with no specialist skills or equipment needed. The embankment can be overfilled and compacted, then trimmed to finished batter as normal.

The TensarTech NaturalGreen System

TensarTech Natural Green is a complete System, including both products and services.

On-site assessment and construction advice are available as part of this service when required, as well as construction drawings and a full design service using state-of- the-art software. The specific products include Tensar uniaxial geogrid reinforcement - which is BBA certified for 120-year design life - and erosion mats (from others).

Single Source Solution

Tensartech NaturalGreen system makes it easy to find a complete solution from just one source. Using Tensar’s sophisticated TensarSoil software, we can provide everything from free application suggestions, all the way up to a full design and supply service.

Proven Solution for Steepened Slopes and Slip Repair

The cost-effectiveness and versatility of the TensarTech NaturalGreen System offer clients, specifiers, and contractors many advantages over other steep slope or retaining wall construction methods. Thousands of steep slope and slope repair projects have been completed around the globe, creating stable, natural slopes with up to a 45° face angle.

For steeper slope faces - greater than 45° - the TensarTech GreenSlope system can provide the optimum, single-source solution.

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.

The Strength Behind the TensarTech NaturalGreen 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. Their open aperture structure interlocks with natural fill materials, making them ideal for reinforced soil applications. The high pH associated with some recycled aggregates does not affect the durability and functionality of HDPE geogrid reinforcement during a life of up to 120 years.
