Geofabrics® Geogrid™ Biaxial are stiff monolithic geogrids engineered for load support in two directions (longitudinal and transverse), Geogrid Biaxial is ideal for subgrade stabilisation, pavement stabilisation, and base layer improvement. They enhance aggregate confinement and reduce rutting in road construction.
Manufactured from polypropylene, this high-performance geogrid is designed for use in Mechanical Stabilised Layers (MSL) with granular fill to efficiently distribute loads over wider areas. Its open aperture design interlocks with a wide range of fill materials, improving soil confinement and stability.

WHY CHOOSE GEOFABRICS GEOGRID BIAXIAL?
- Reduces aggregate layer thickness without compromising performance, lowering excavation and fill costs
- Cuts costs and CO emissions by reducing excavation, transport and aggregate use during construction
- Enhances layer stiffness to allow the use of lower-quality or recycled fill materials, reducing material costs
- Improves pavement resilience by spreading heavy loads and reducing differential settlement
- Performs even in harsh conditions, by maintaining stiffness and stability in challenging weather and soil environments
- Speeds up installation, offering a fast, cost-effective stabilisation solution for roads, working platforms and heavy-vehicle pavements
- Backed by performance, international research and field trials
- All geogrids are manufactured in accordance with a management system which complies with the requirements of ISO 9001:2015
INSTALLING GEOGRID BIAXIAL
Geogrid biaxial is simple to handle and install on site, providing an efficient solution for pavement applications. It can be rolled out directly over subgrade after removal of protrusions such as rocks and tree stumps.
Geofabrics New Zealand provides dedicated technical support and advanced design tools to assist engineers in developing safe, durable and cost-effective solutions for a wide range of infrastructure, transport and mining applications and projects.

FUNCTION
Reinforcement
Geosynthetics provides additional strength to soils and aggregate. Used to reinforce steep slopes, and to stabilise road or rail construction over weak and variable soils. Enables embankments to be constructed over very soft foundations and to build slopes at steeper angles than would be possible with unreinforced soil. Geosynthetics (or geogrids) are also used to bridge over voids that may develop below load bearing granular layers (roads and railways) or below cover systems in landfill applications.
Stabilisation
Improvement of the mechanical behaviour of an unbound granular material by including one or more geosynthetic layers such that deformation under applied loads is reduced by minimising movement of the unbound granular material. Stabilisation geosynthetics are predominantly applicable to the improved performance of bases and subbases of trafficked areas such as roadways, railways, airfields, and working platforms.
