Interlock 20
Biaxial extruded polypropylene geogrid.
Used in multiple foundation solution applications, in both temporary works and permanent works. The roll widths have been selected to eliminate longitudinal overlaps in some haul road applications and reduce wastage and installation time in all trafficked and hardstanding applications.
Suitable applications include:
Interlock Geogrids are manufactured from highly orientated (punched and stretched) monolithic polypropylene sheets with integral nodes, specifically for the reinforcement and stabilisation of unbound granular soils. The junctions and rib geometry facilitate mechanical interlock with the granular soil layers.
Functions: Interlock Geogrids are robust - they have a tensile strength at high levels of strain, to provide the necessary reinforcement function, to resist installation damage during the initial construction phase. Interlock Geogrids are stiff - they have a high modulus at low levels of strain, to provide the required stabilisation function, to enhance or maintain the foundation stiffness whilst in-service.
