MastaGRID™ Poly Geogrid

MastaGRID™ Poly is an engineered polypropylene geogrid designed for soil stabilisation, separation & reinforcement applications. This is done through the process of extruding, polypropylene sheets then both stretching in both longitudinal and transverse directions.

MastaGRID™ Poly rigid biaxial geogrids perform best in granular, angular fills and are used under roads, railways, loading platforms for sub-base soil reinforcement & stabilisation.

APPLICATIONS INCLUDE:

  • Base Reinforcement
  • Subgrade Reinforcement
  • Embankment Stabilisation
