Geofabrics® Geogrid™ Triaxial is a high-performance, multi-axial geogrid engineered for soil stabilisation and ground improvement in road, rail and heavy-duty pavement applications.
Manufactured from a punched polypropylene sheet, it forms a unique hexagonal structure with triangular apertures that confine and interlock with aggregate. This interlocking mechanism creates a Mechanically Stabilised Layer (MSL) that improves load distribution, increases bearing capacity and enhances pavement performance on soft or variable ground conditions

Geogrid Triaxial delivers superior stiffness and stability compared with conventional biaxial geogrids reducing material requirements, construction time, and environmental impact across infrastructure, transport and industrial projects.
WHY CHOOSE GEOFABRICS GEOGRID TRIAXIAL?
- Reduces aggregate layer thickness without compromising performance, lowering excavation and fill costs
- Improves bearing capacity and stabilises ballast layers on rail projects, minimising track movement and maintenance requirements
- Enhances layer stiffness to allow the use of lower-quality or recycled fill materials, reducing material costs
- Cuts CO₂ emissions by reducing excavation, transport and aggregate use during construction
- Increases pavement resilience by spreading heavy loads and reducing differential settlement
- Performs in harsh conditions, 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 proven performance, with international research and field trials demonstrating superior results compared to conventional geogrids
- All geogrids are manufactured in accordance with a management system which complies with the requirements of ISO 9001:2015
INSTALLING GEOGRID TRIAXIAL
Geogrid Triaxial is relatively simple to handle and install on site, providing an efficient solution for stabilising soil and improving ground condition for heavy-duty pavement. 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
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.
