{"product_id":"geogrid","title":"Biaxial Geogrid for Soil Reinforcement","description":"\u003cp\u003eBiaxial geogrid is an integrally formed, rigid mesh structure engineered for demanding soil stabilisation and ground reinforcement applications. Manufactured from polypropylene (PP) through a process of extrusion, longitudinal stretching, and transverse stretching, it delivers exceptional tensile strength in both the machine direction (MD) and transverse direction (TD). The result is a structurally stable, mechanically interlocking grid that effectively confines and reinforces aggregate layers under load.\u003c\/p\u003e\n\u003ch2\u003eApplications of Geogrid\u003c\/h2\u003e\n\u003cp\u003eBiaxial geogrid is suited to a wide range of civil and construction applications, including base reinforcement, subgrade reinforcement, slope reinforcement, and embankment stabilisation. It performs reliably under roads, driveways, parking lots, and retaining wall systems where load distribution and lateral restraint are critical.\u003c\/p\u003e\n\u003ch2\u003eHow Geogrid Works\u003c\/h2\u003e\n\u003cp\u003ePP sheets are punched with apertures and stretched under heat, aligning the polymer molecules to create high tensile resistance. When aggregate is placed over the geogrid, the particles interlock within the apertures - acting like a snowshoe to distribute vertical loads over a wider footprint and prevent lateral migration of fill material.\u003c\/p\u003e\n\u003ch2\u003eGeogrid vs Geotextile – Understanding the Difference\u003c\/h2\u003e\n\u003cp\u003eGeogrids and geotextiles serve distinct but complementary roles. A \u003cstrong\u003egeotextile\u003c\/strong\u003e is a fabric-like material whose primary functions are separation (preventing base rock from sinking into soft subgrade) and filtration (allowing water to pass while retaining fine soil particles). A \u003cstrong\u003egeogrid\u003c\/strong\u003e is a stiff, open mesh whose primary function is reinforcement and stabilisation - it locks into gravel or crushed rock to bear and distribute heavy loads.\u003c\/p\u003e\n\u003ch2\u003eHow Geogrid and Geotextile Work Together\u003c\/h2\u003e\n\u003cp\u003eWhen used in combination, these two materials form a complementary dual-layer system that significantly improves the performance and longevity of civil structures:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePreventing pumping in roadways:\u003c\/strong\u003e Over weak or muddy subgrades, the geotextile separates mud from the gravel base while the geogrid locks the gravel together - preventing rutting and bearing capacity failure under traffic.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReinforcing retaining walls:\u003c\/strong\u003e For walls exceeding 1–1.2 metres, geogrid layers are embedded into the backfill to anchor the wall into the earth.
