Geogrids

Geogrids are advanced geosynthetic reinforcement products that strengthen soil, improve ground stability, and extend pavement life in construction and mining projects. HEIGER’s range includes biaxial, uniaxial, triaxial, composite, and asphalt reinforcement grids, each engineered to meet Australian ground conditions and design standards. These products are trusted for subgrade stabilisation, retaining wall reinforcement, slope protection, roadbase confinement, and rail or mining haul road construction.

Developed for large scale applications in civil construction and mining, HEIGER geogrids provide predictable performance and design-ready data for efficient ground improvement. They work by interlocking with aggregate to distribute loads evenly, reduce rutting, and improve soil stiffness. This means faster construction, lower aggregate costs, and long-term structural stability even on soft or variable subgrades.

Every HEIGER geogrid is manufactured under strict ISO 9001 and ISO 14001 standards, using recyclable polypropylene (PP) or polyester (PET) polymers without PVC or harmful additives. They are UV-stabilised for long design life and maintain full tensile strength for decades under Australian environmental conditions. By improving subgrade performance and reducing aggregate requirements, HEIGER geogrids help lower CO₂ emissions and support Green Star and Infrastructure Sustainability (IS) rating credits.

All products are tested to ISO 10319 and AS 4678 and come with independent third-party verification, LTDS data, and full design documentation. With rapid local delivery, in-house engineering support, and consistent batch-tested quality, HEIGER offers reliable reinforcement solutions for roads, retaining structures, rail networks, and mining infrastructure.

What Are Geogrids?

Geogrids are structural reinforcement materials made from high-strength polymers that interact with soil or aggregate to create a stable composite layer. When placed under roads, embankments, or retaining walls, they limit soil movement, increase bearing capacity, and extend the service life of the structure. HEIGER supplies multiple grid types to suit different applications, from civil infrastructure to mining and industrial projects.

Biaxial and Triaxial Geogrids for Ground Stabilisation

Biaxial geogrids provide tensile strength in two directions, ideal for stabilising subgrades and reducing deformation in pavements, access roads, and working platforms. Triaxial geogrids offer strength in multiple directions using a triangular aperture pattern, improving load transfer for heavy-duty haul roads, container yards, and port facilities. These grids reduce aggregate thickness and construction time while improving overall pavement stiffness and durability.

Common applications include: 

1. Road and highway foundations

2. Rail trackbeds and ballast reinforcement

3. Industrial yards and container terminals

4. Temporary construction pads and crane platforms

Working platforms on weak subgrades

Uniaxial Geogrids for Retaining Walls and Slopes

Uniaxial geogrids provide strength in one direction and are designed for soil reinforcement in retaining walls, bridge abutments, and steep slopes. Made from high-tenacity PET yarns, they deliver long-term design strength with low creep. They are often combined with modular blocks or wrapped-face systems in mechanically stabilised earth (MSE) structures.

Typical applications include:

1. Segmental retaining walls

2. Reinforced soil slopes and embankments

3. Bridge abutments and road approach fills

4. Railway embankments and slope repairs

Composite and Asphalt Reinforcement Geogrids

Composite geogrids bond a geotextile to a geogrid layer, providing both reinforcement and separation in one product. They are effective where soil pumping or fine particle migration is a risk, such as in rail formation or low CBR ground. Asphalt reinforcement grids are used to control reflective cracking in pavement overlays, improving fatigue life and reducing maintenance costs on highways and airports.

Applications include:

1. Soft soil stabilisation and separation

2. Road rehabilitation and overlay systems

3. Airport runway resurfacing

4. Drainage and filtration layers in weak subgrades

Mining and Heavy-Load Geogrids

HEIGER supplies FRAS-rated (Fire Retardant and Anti-Static) geogrids designed for underground and surface mining. These heavy-duty PET grids provide exceptional durability under high loads and harsh conditions. Their high junction strength and long-term performance make them ideal for haul roads, access tunnels, and waste stockpile foundations.

Applications include:

1. Underground mine roadways

2. Haul roads and ramp reinforcement

3. Slope stabilisation in mining pits

4. Working platforms for drilling and heavy plant

Sustainable, Tested, and Locally Supported

 Every HEIGER geogrid is manufactured with sustainability in mind. Facilities use energy-efficient extrusion, recyclable materials, and environmentally safe coatings. Local warehousing across Australia reduces transport distances and delivery emissions. All products undergo testing to ISO 10319, ISO 13431, and ASTM D5262, ensuring reliable long-term performance. HEIGER’s in-house engineering team supports contractors with design data, specification sheets, and fast turnaround quotes.

With consistent quality, local availability, and complete technical documentation, HEIGER geogrids give engineers and contractors confidence in compliance, performance, and durability across every project scale.
