Steep Slopes

Due to continually increasing land costs and environmental restrictions, engineers frequently depend upon steep slopes to maximise the available space. TensarTech reinforced soil solutions, using Tensar Technology, are not only environmentally attractive with vegetated faces and simple to construct, but can even offer large cost savings – as much as 75% – over alternative methods.



Different systems for different slopes

The choice of the most appropriate solution for your project will rely on the face angle of slope. On face angles of up to 45˚, normally it is not necessary to have a structural facing, but for angles over 45˚, some form of permanent facing is required. With this in mind, Tensar offers two standard systems, both of which make use of our geogrids and 30 years of experience as specialists in soil reinforcement:

TensarTech NaturalGreen  has proven performance for new build slopes up to 45˚, and also many slip repairs. The system uses horizontal layers of geogrid within the soil for long-term stability, together with a surface matting to enhance erosion resistance

TensarTech Greenslope  is designed for slopes between 45˚-70˚, with layers of geogrid within the soil mass connected by Tensar’s efficient bodkin method to modular, durable steel facing units. The face is lined with suitable anti-erosion material, which allows vegetation cover to establish. The facing units can be terraced to produce a varying overall slope face angle.

Whatever your project, we can help

Tensar’s technology has been used on slopes globally, and a full range of case studies and brochures are available. We can  provide full technical support including expert advice, specifications, drawings, certified designs and details of pricing, and we regularly run free workshops the world over. 


Economical, practical solutions for steep-faced embankments

TensarTech reinforced soil solutions, using Tensar Technology, are not only environmentally attractive with vegetated faces and simple to construct, but can even offer large cost savings – as much as 75% – over alternative methods.

The benefits

Whichever TensarTech System is right for your project, the benefits of Tensar reinforced soil slopes remain the same:

  • Simple construction, which can reduce cost and build time
  • Optimise the use of available space
  • Use site-won fill (including cohesive or contaminated) or recycled fill
  • Tolerant of differential settlement
  • A design life of up to 120 years
  • High resistance to seismic loading
  • Often provides avoidance of expensive foundation treatment
  • Maximises the plateau area on a sloping site
  • Minimises encroachment into environmentally-sensitive areas
  • Provides a soft face alternative to hard face retaining walls in sensitive areas
