The NAUE STEEL P system combines Secugrid® geogrid reinforcement with
longterm (permanent) steel-skin facings to create reinforced earth
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.
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 galvanized steel facing, Secutex ® nonwoven filter
geotextiles or Secumat ® erosion control mats are used. The system is
highly adaptable to project-specific requirements and geometries,
resulting in economical solutions supporting natural vegetation.


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

System Components:

  • Secugrid® PET geogrid reinforcement
  • Secumat® erosion control mat and/or nonwoven Secutex® geotextile
  • Fasteners
  • Hydroseeding
  • Galvanized steel facings


  • 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 noncohesive
  • Secugrid® geogrids can be used with cement- and limestabilized soils
  • Ecological benefits associated with the use of local soils include
    decreased transportation pollution (and cost) and conservation of
    natural resources
