Building natural looking retaining walls and embankment protection

With our Fortrac Nature system models, you can erect vegetation covered retaining walls or embankment protection in a short time, which, when appropriately planted, integrates into the landscape. Compared with conventional construction methods, this natural solution has a positive effect on the urban climate and, if appropriately planted, offers protection for insects and birds. You can use the system for slope and embankment protection with inclines from 30° to steep slopes and steep slopes up to 110°.  Successful, permanent vegetation is usually possible up to an angle of inclination of 70° and should be ensured by a specialist company in cooperation with the planner. Of course, temporary structures and earth pressure vessels do not require any greenery.


System benefits

  • Harmonious integration in natural landscape setting
  • High flexibility in terms of inclination, contouring and vegetation
  • Long-term stability and durability coupled with ductile behaviour
  • Natural looking solution, providing habitat for birds and insects
  • Positive impact on micro-climate
  • Easy dismantling allows use as a temporary structure
  • Lateral earth pressure containments of 110° feasible

System models

Integrated corrosion-protected formwork

  • Integrated galvanised steel formwork
  • Long-term stability and high resistance to deformation 
  • Space efficient installation without ancillary formwork

Integrated lost formwork

  • Integrated pre-formed structural steel formwork
  • High stability and resistance to deformation
  • Space-efficient installation without ancillary formwork

Without integrated formwork

  • Low system costs
  • Erection and shaping with temporary ancillary formwork
  • Customised architectural contouring possible
