The NAUE WRAP Secugrid® geogrid system for reinforced earth
structures utilizes Secugrid® in wrapped, reinforcement envelopes at
slope fronts. Temporary formworks, such as wood piles, are used in the
site preparation and construction process. Mechanical protection of the
high load-bearing capacity of NAUE’s Secugrid® reinforcement technology
is secured by the installation of Secumat® erosion control mats or
Secutex® nonwoven geotextiles. These measures protect against erosion of
the soil. NAUE WRAP is highly adaptable to project-specific
requirements and geometries, which leads to an economical, aesthetic
solution capable of supporting vegetation. Slope surfaces at angles up
to 70° can be vegetated. Additional UV protection can be provided
through the installation of facing stones or other adequate materials.


  • Vegetated slopes between 45° and 70°
  • Retaining walls up to 90°, in combination with a panel facing

System Components:

  • Secugrid® PET geogrid for primary reinforcement
  • For taller constructions, Secugrid® PET geogrid for secondary reinforcement between layers
  • Temporary formworks
  • Secumat® erosion control mat or Secutex® nonwoven geotextiles
  • Fasteners
  • Hydroseeding


  • Permanent stability even on slopes up to 90°
  • One source/system for all reinforcement needs
  • Natural, green-faced constructions
  • Conserves construction resources (and costs), as site formworks can be reused
  • Simple construction
  • High load capacity
  • Site soils (including cohesive soils) can be used, which optimises
    project economy since more-affordable cohesive soils can be used rather
    than disposed of or replaced with non-cohesive soils
  • Secugrid® geogrids can be used with soils stabilized with cement or lime
  • Variable spacers allow site-specific slope face adjustment
  • Ecological benefits associated with the use of local soils include
    decreased transportation pollution (and cost) and conservation of
    natural resources
