Vegetated embankments and steep slopes are favoured methods of construction for infrastructure projects, including roads, bridges and railways. Tensar International’s Tensartech NaturalGreen and GreenSlope Systems, for reinforced earth retaining slopes up to 45º and 70º respectively, offer rapid and low cost construction, proven performance, and high sustainability with excellent vegetated finishes to complement the local environment.

Two new brochures - Tensartech NaturalGreen for slope faces to 45º and Tensartech GreenSlope for slope faces to 70º - demonstrate the ease of the installation methods used and the pleasing aesthetics of the results.

Both methods are based on the use of Tensar’s uniaxial geogrids in horizontal layers to stabilise and reinforce the soil mass. This technique frequently allows the use of site-won or local-fill materials for the slopes, including colliery spoil and slag, and saves the transportation of costly imported aggregates.

The Tensartech NaturalGreen system combines a stable slope structure with an erosion protection composite incorporated on the slope face. The composite provides the moisture retention and reinforcement the vegetation needs for establishment and a strong root system to resist erosion and provide stability at the face.

The Tensartech GreenSlope system is designed for steeper slopes up to 70º by installing durable steel facing units, positively connected to the geogrids in the reinforced soil mass. The facing units are backed with topsoil helping the chosen vegetative cover to become established on the slope. The technique is rapid and simple, allowing continuous or terraced slopes to be built without time consuming and expensive formwork to maintain alignment. As well as a highly attractive finish, Tensartech GreenSlope can offer cost reductions of over 75% compared to conventional techniques such as reinforced concrete.
