WHY CHOOSE GEOGRID BITEX GEOCOMPOSITE
- Separation, filtration and interlock in one product delivers multiple geotechnical functions simultaneously, improving installation efficiency and performance
- Superior structural strength - forms a stiff Mechanically Stabilised Layer (MSL) that enhances load distribution, controls differential settlement and increases bearing capacity
- Cost-efficient construction due to reduced aggregate thickness, less excavation and faster installation for more economical project outcomes
- Enhanced drainage performance as it maintains permeability and allows efficient water flow, preventing pore pressure build-up and preserving pavement integrity
- Long-term durability by prevention of soils mixing and restriction of fine particle migration
- Sustainable design - incorporates locally manufactured non-woven geotextile layer made from recycled PET and virgin materials, supporting environmentally responsible construction
- Reduced maintenance downtime and closure by using integrated product
- All geogrid geocomposites are manufactured in accordance with a management system which complies with the requirements of ISO 9001:2015
INSTALLING GEOGRID BITEX GEOCOMPOSITE
Geogrid Bitex geocomposite is simple to handle and install on site, it can be rolled out directly over subgrade after removal of protrusions. The speed of installation and reduction in aggregate required can result in significant time and cost savings.
Geofabrics Australasia 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
Filtration
Geosynthetics can act as a filter by allowing water to move freely through while preventing the migration of fine particles. Often used to prevent soils from migrating into drainage aggregate or pipes while maintaining flow. Can also prevent soil erosion in coastal and riverbanks when used below loose stones or rocks and other material.
Separation
Geosynthetics can be used to prevent the intermixing of soil types of different sizes in the construction of roads, railways, and embankments where the ground is soft and unstable to maintain the integrity of each material while allowing free passage of liquids or gases. Using a layer of geotextile to separate the soft ground from the fill material reduces the amount of fill required, increases the lifespan of the road or rail structure and cuts long-term maintenance costs.
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.
