MastaGRID™ Composite Geogrid

mastaGRID™ Composite is an engineered geogrid designed for soil stabilisation, separation and reinforcement applications. mastaGRID™ Composite is manufactured from Polypropylene through the process of extruding, longitudinal and transverse heat stretching. mastaTEX™ is then heat bonded to the grid to form a sound composite structure.

It is designed to prevent reflection cracking, water damage and improve load capacity in road construction and renovation. It has the property of high temperature resistance and anti-fatigue cracking and therefore extending the life and time of asphalt pavements.

APPLICATIONS INCLUDE:

  • Base Reinforcement
  • Embankment Stabilisation
  • Subgrade Reinforcement
  • Subgrade Reinforcement
