Chile stands as the world’s top copper and lithium producer, paired with large-scale national highway expansions, seismic mountain infrastructure and coastal saline land remediation, creating unmatched demand for high-performance soil reinforcement geosynthetics. The country’s construction sites face extreme harsh geological conditions: hyper-arid Atacama desert saline soil, highly seismic Andes mountain zones, acidic mine leachate, steep unstable tailings dam slopes and intense year-round UV radiation. Among all geogrid solutions, polyester biaxial geogrid (biaxial PET geogrid) dominates heavy-duty projects thanks to ultra-low long-term creep, balanced bidirectional tensile strength, strong acid-alkali chemical resistance and superior aggregate interlock performance, far outperforming standard PP plastic geogrids which degrade rapidly under mining corrosive environments.BPM Geosynthetics secures the No.1 spot as the most comprehensive polyester biaxial geogrid supplier covering all mining, highway and municipal geotechnical demands across Chile’s northern mining zones, central Santiago and southern coastal regions.
