Corden EPS biaxial geogrids are punched and drawn polypropylene grids designed to reinforce granular sub-bases, capping layers, piling platforms and railway ballast in areas with weak or variable soils. Engineered for long-term durability, this range maximises stone interlock and load dispersal, supporting reduced sub-base thickness and construction costs.

  • Punched and drawn polypropylene geogrid for soil reinforcement

  • Optimised rib height and open aperture area for strong stone interlock

  • Design life exceeds 100 years

  • Supports single or multilayer installation

  • Improves load distribution and shearing resistance

  • Enables thinner sub-base layers, reducing material use and costs

  • Suitable for reclaiming weak soils for development
