Railgrid - Track Reinforcing Composite

  • Extruded Biaxial polypropylene geogrid.
  • Large (65mm) apertures help promote optimum amount of ballast interlock.
  • For use where the total depth of the ballast layer is not sufficient to give absolute minimum value of track stiffness.
  • Mechanical interlock of aggregate through the grid produces high stiffness through transverse and longitudinal dimensions.
  • Can be used ‘mid-layer’ to improve stiffness where ballast depth exceeds 300mm, e.g. on adverse cant curves.

Ground stabilisation grid has equal strength in both longitudinal and transverse directions a recognised advantage in sub-base reinforcement.

Railgridis manufactured by Tenax Spa, Italy and marketed in the UK and Ireland by Aqua Geocomposites Ltd as Railgrid.


  • Extruded Bi-Axail polypropylene geogrid, 65mm large square aperture, tensile strength 30KN/m.


  • Improved track geometry. Large aperture grid promotes optimum ballast interlock.
