Exploring the Future of Soil Reinforcement: TerraGrid® High Strength Geogrid (HSG)

installation of Terragrid HSG

In the field of civil engineering, where material integrity is critical, TerraGrid® HSG emerges as a greener option with a lower carbon footprint. It stands out as a technically compliant (NSW RMS/Qld TMR/VicRoads compliant) and economically efficient solution compared to conventional methods like excavate, replace, and compact select fill geotechnical solutions.

Engineered from high-tenacity polyester (PET) yarns, these structured grids are meticulously designed to provide robust reinforcement for a variety of applications, which include:

  • Granular Soil Reinforcement Working Platforms: Enhances the stability and load-bearing capacity of soft, weak clay soil foundations.
  • Embankment Support: Provides essential basal reinforcement to prevent rotational slip failure and improve global stability.
  • Retaining Structures and Slopes: Distributes loads effectively to ensure the stability of retaining walls and reinforced slope structures.
  • Piling and Crane Platforms: Creates a stable working platform crucial for piling and crane operations on soft, deep, weak foundations, improving the operational safety of piling rigs and cranes.
  • Subgrade Improvement: Improves weak, soft, clay subgrade conditions to support heavy traffic loads and enhance overall performance for temporary and permanent flexible roads.

Introducing TerraGrid® HSG

Revolutionising soil reinforcement, TerraGrid® High Strength Geogrid (HSG) is a high-tenacity PET solution designed to meet the most demanding technical applications. For added functionality, an optional 150gsm nonwoven geotextile can be bonded on one side.

TerraGrid® HSG is ideal for:

  • Reinforcing granular soils
  • Supporting embankments on soft, weak clay foundations
  • Stabilising retaining walls and slopes with a wrap-around facing
  • Base reinforcement on soft, weak clay foundations
  • Creating working platforms using select granular backfill
  • Improving clay subgrade conditions with optional separation geotextile, ideal when the saturated ground CBR is less than 3%.

With its innovative design and exceptional performance, TerraGrid® HSG sets a new standard in soil reinforcement.
