Geogrid is a geosynthetic material used to strengthen soil including subbase for roads and to reinforce retaining walls. The main feature of geogrids is their ability to allow soil to anchor to structures through the geogrids apertures and ribs.


  • Roads, railways, ports and other paved areas
  • Airport runways
  • Temporary roads and other unpaved areas
  • Slopes Reinforcement
  • Environmental protection of slopes
  • Landfill Sites

Biaxial Geogrid

PERMAGRID Biaxial Geogrids are square meshes of polypropylene (PP) and widely used as subsoil reinforcement. Their prominent characteristic is excellent mechanical properties under intermittent high loading. As a bi-axial mesh strength is equal in both machine and cross directions which allows for loads in any direction of the plane.

Uniaxial Geogrid

PERMAGRID uniaxial Geogrids are meshes with elongated apertures made of high density polyethylene (HDPE) and are generally used as reinforcement of modular block walls, earth walls, slopes and bridge abutments. Their primary characteristic is good creep performance with low strain and high tensile strength under constant load.
