Biaxial Geogrid

Biaxial 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. Applications of Geogrid

Biaxial 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. How Geogrid Works

PP 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. Geogrid vs Geotextile – Understanding the Difference

Geogrids and geotextiles serve distinct but complementary roles. A geotextile 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 geogrid 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. How Geogrid and Geotextile Work Together

When used in combination, these two materials form a complementary dual-layer system that significantly improves the performance and longevity of civil structures:

- Preventing pumping in roadways: 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.
- Reinforcing retaining walls: For walls exceeding 1–1.2 metres, geogrid layers are embedded into the backfill to anchor the wall into the earth. A geotextile placed behind the blocks filters fine soil and protects the drainage system.
- Reducing excavation costs: The combined system achieves a stronger foundation with less imported rock and reduced dig depth - a meaningful saving on larger projects. Specifications of

- Material: Polypropylene (PP)
- Structure: Integrally formed biaxial grid
