Cost-effective reinforcement

TerraGrid Core

TerraGrid Core is a biaxial geogrid that provides a cost-effective solution to solve pavement problems by providing omni-axial reinforcement to granular sub-bases, capping layers and railway ballasts in areas of weak or variable soils.

Applications and benefits

TerraGrid Core allows granular particles to be compacted over them, partially penetrating and projecting through the apertures. This creates a strong and positive interlock; the interlocking mechanism increases shearing resistance within the soil, improving compaction and allowing the sub-base thickness to be decreased while dispersing loads.

TerraGrid Core comes as standard in 4m roll widths. For haul road applications, this can often completely eliminate the need for overlaps across the width of the road, significantly reducing wastage. With TerraGrid Core, you can reduce construction time, costs and even CO2e.

Benefits of TerraGrid Core

  • Very low maintenance system
  • Cost-effective
  • 4m roll width as standard
  • Also available as a composite geogrid and geotextile

Achieve significant savings

Reduce your projects carbon emissions

Our geogrids can play a significant role in reducing carbon emissions across a project. There's numerous ways this is achieved, including:

  • By reducing the amount of earthworks required on-site before the grids go into the ground. This reduces the amount of plant required, and their associated emissions.
  • Reducing the thickness of a haul road, compound or similar. This thickness is created with aggregate which requires extraction, processing, and transport. By minimising the aggregate you will significantly reduce embodied carbon. Our geogrids can provide equivalent load-bearing capabilities to sub-bases twice as thick, providing aggregate savings of up to 50%.
  • Minimising the likelihood of repairs. Geogrids provide reinforcement, leading to higher quality, stronger sub-bases, which can result in longer-lasting and harder-wearing installations, requiring less repairs and maintenance.

Have you considered TerraGrid Core Composite?

Achieve time savings when acquiring materials and overall quicker installations, thanks to TerraGrid Core Composite, an all-in-one solution that performs as both a biaxial geogrid and a geotextile. TerraGrid Core Composite consists of nonwoven geotextile thermally bonded to our popular SX range of geogrid. It provides the functions of reinforcement, separation and filtration into one single product, rather than having to use two separate solutions, which offers significant savings.
