PP GEO GRID

TerraShield PP Geogrid is a grid-like structure made from polypropylene strips or ribs that are stretched and oriented in one or two directions. This creates a high-tensile, lightweight mesh that interlocks with soil, aggregate, or other fill material to improve stability.

Applications

Road & Railway Construction

Retaining Walls

Slope stabilization

Embankments over soft soil

Landfills & Ground improvement projects

Features

  • High tensile strength and low elongation — ideal for soil reinforcement.
  • Excellent resistance to chemical, biological and hydrocarbon attack.
  • Low creep behaviour ensures long-term structural performance.
  • Lightweight, easy to transport and quick to install on site.
  • Good interlock with granular infill for load distribution.
  • Cost-effective solution for retaining walls, base reinforcement and slopes.
  • Available in uniaxial or biaxial configurations to match load direction.
