NAUE Steel P system for reinforced slopes and reinforced walls

The NAUE Steel P system combines Secugrid® geogrid reinforcement with longterm (permanent) steel-skin facings to create reinforced soil structures amenable to numerous slope shapes. Vegetation is allowed on slopes up to 70°. For steeper slopes on which vegetation is desired, special plantings and irrigation are necessary.

For NAUE Steel P, the Secugrid® primary reinforcement is fastened to the steel shells (e.g., L-shaped wire forms) to create a strong interface. To prevent soil erosion along the galvanised steel facing, Secutex® nonwoven filter geotextiles or Secumat® erosion control mats are used. The NAUE Steel P system for reinforced slopes and reinforced walls is highly adaptable to project-specific requirements and geometries, resulting in economical solutions supporting natural vegetation.

NAUE Steel P reinforced slopes and reinforced walls applications

  • Landslide, slope and embankment restorations
  • Slope stabilisations up to 70°
  • Vegetated slopes with gradients between 45° and 70°
  • Retaining wall structures up to 90°
  • Road and rail noise barriers

Advantages of NAUE Steel P

  • Permanent stability even up to 90°
  • Green solution
  • High load capacity
  • Variable spacers allow site-specific slope face adjustment
  • Quick and easy construction
  • Site soils (including cohesive soils) can be used
  • Extremely economical, due to the ability to utilise more-affordable cohesive soils rather than dispose of or replace them with non-cohesive soils
  • Secugrid® geogrids can be used with cement stabilised and lime stabilised soils
  • Ecological benefits associated with the use of local soils include decreased transportation pollution (and cost) and conservation of natural resources

System components
