NAUE BLOCK

When embankments are planned with angles exceeding 70°, a vegetated
face is usually not possible or requires significant and potentially
cost-prohibitive work. These situations require harder exteriors, which
elevates the importance of surface aesthetics to the reinforced
structure. NAUE BLOCK is a Secugrid® geogrid system for reinforcing
earth structures and walls while incorporating brick, block, precast
concrete, natural stone and other facings for design flexibility.
Secugrid® geogrids are placed between the facing elements and anchored
in the soil for outstanding structural stability. This strength enables
NAUE BLOCK to adapt to projectspecific requirements, allows numerous
wall shapes (including rounded corners), and results in economical,
aesthetic solutions. Where needed, additional mechanical protection can
be provided with the installation of a nonwoven geotextile filter behind
the facing. Walls and slopes can be built to 90° angles.

Applications:

  • Retaining walls of all kinds
  • Embankment constructions
  • Bridge abutments
  • As a replacement for gravity walls
  • Road and rail noise barriers

System Components:

  • Primary Secugrid® PET geogrid reinforcement
  • Bricks, block, precast concrete, natural stone or dry stone wall facing
  • Secutex® nonwoven filter geotextile, depending on the project

Advantages:

  • Quick and easy to construct
  • Flexible design of facing
  • 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 cement- and limestabilized soils
  • Ecological benefits associated with the use of local soils include
    decreased transportation pollution (and cost) and conservation of
    natural resources.
