NAUE STEEL T utilizes the primary reinforcement of Secugrid® geogrids
combined with temporary effective steel-skin facings in enveloped forms
to create a reinforced earth construction system that can adapt to
numerous slope angles and shapes while supporting vegetation. Plantings
are possible on the face of NAUE STEEL T on slopes up to 70°. For
steeper slopes, special vegetation measures and irrigation systems are
generally necessary. Secutex® nonwoven geotextiles or Secumat® erosion
control mats provide slope face erosion control. The system enables
considerable design flexibility, thus allowing adaptation to
project-specific requirements and wall shapes while being highly
economical, quick to construct, and aesthetically attractive with a
natural, green face.


  • 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
  • Steel (permanent) formwork, such as steel mesh


  • 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
