TerraGrid Core Biaxial Geogrid
TerraGrid Core is a biaxial geogrid designed to deliver reliable reinforcement of granular layers in civil engineering and construction projects. Manufactured from extruded polypropylene, it features a rigid, open structure that allows aggregate particles to interlock within its apertures. This creates a mechanically stabilised layer that improves compaction, distributes loads more effectively and reduces lateral movement of fill.
With strength in both longitudinal and transverse directions, TerraGrid Core is suited to projects where traffic loading is variable and long-term performance is critical. Typical applications include highways, access roads, rail embankments, car parks and working platforms. By reinforcing aggregate layers, TerraGrid Core reduces deformation and the formation of soft spots, extending the service life of the structure.
In line with BS 8661:2019 guidance, biaxial geogrids can be specified to improve performance where weaker soils are present and reinforcement is required. TerraGrid Core helps limit the thickness of imported granular materials, supporting more efficient pavement designs while reducing both construction costs and embodied carbon.
Its robust design ensures resilience during installation, withstanding handling, trafficking and the placement of angular aggregates without damage. This reliability, combined with consistent tensile strength in two directions, makes TerraGrid Core a dependable choice for demanding ground conditions.
Available in a range of grades to suit site-specific requirements, TerraGrid Core is CE-certified and supported by full technical data. Geoworks also provides CPDs and design advice, giving specifiers confidence in both the selection and application of the product.
TerraGrid Core offers a straightforward, proven solution for ground reinforcement. By improving aggregate efficiency, reducing maintenance needs and supporting sustainable construction practices, it helps engineers deliver durable and cost-effective infrastructure.
