ENGINEERED GEOCOMPOSITE SOLUTIONS FOR DRAINAGE, REINFORCEMENT, SEALING AND GROUND STABILISATION
Geocomposites combine two or more geosynthetic materials into a single engineered product to deliver multiple performance benefits within one solution. By integrating the strengths of geotextiles, geogrids, drainage cores, geomembranes and other geosynthetic components, geocomposites can simplify construction, reduce material requirements and improve long-term infrastructure performance.
We offer a comprehensive range of geocomposites for civil infrastructure, transport, environmental, mining and construction applications. Our geocomposite products are engineered to improve drainage, reinforce pavements, control moisture, reduce reflective cracking, stabilise weak subgrades and support containment systems.
Supported by technical expertise and national distribution, our geocomposite solutions help engineers and contractors specify proven systems that deliver reliable performance across demanding project environments.
WHAT ARE GEOCOMPOSITES AND HOW DO THEY WORK?
A geocomposite is a geosynthetic product manufactured by combining two or more materials, such as geotextiles, geogrids, geomembranes or drainage cores, to perform multiple engineering functions within a single system.
Geocomposites are used for drainage, reinforcement, filtration, separation, containment, pavement improvement, ground stabilisation and environmental protection across civil, transport and mining projects.

TYPES OF GEOCOMPOSITES
We offer a range of geocomposites to suit project goals, ground conditions and performance requirements:
DRAINAGE GEOCOMPOSITE
Drainage geocomposites provide efficient collection and conveyance of water while reducing hydrostatic pressure behind retaining structures, beneath roads, around foundations and within landfill and environmental containment systems. Our range includes products suited to vertical, horizontal and subsurface drainage applications where consistent hydraulic performance and long service life are essential.
Typical applications include:
- Retaining wall drainage
- Basement and foundation drainage
- Landfill drainage systems
- Road and pavement drainage
- Embankments
- Vertical wick drains for ground improvement
REINFORCEMENT AND PAVEMENT GEOCOMPOSITE
Reinforcement geocomposites improve structural performance by combining reinforcement with separation or filtration functions within a single product. These systems strengthen pavements, distribute loads more effectively and reduce deformation caused by repeated traffic loading. Our pavement geocomposites are widely used to improve road performance, reduce reflective cracking and extend pavement service life.
Typical applications include:
- Road construction
- Road rehabilitation
- Asphalt overlays
- Pavement reinforcement
- Working platforms
- Industrial pavements
ENVIRONMENTAL PROTECTION GEOCOMPOSITE
Environmental geocomposites support containment and protection systems by combining drainage, barrier and protective functions into integrated solutions. These products assist with environmental compliance while improving installation efficiency and long-term asset performance.
Typical applications include:
- Landfill lining systems
- Waste containment
- Environmental containment
- Water management
- Mining infrastructure
RAIL AND GROUND STABILISATION GEOCOMPOSITE
Ground stabilisation geocomposites improve formation stability where weak subgrades, saturated soils or repeated loading create maintenance challenges. These solutions reduce fines migration, improve load distribution and extend asset life.
Typical applications include:
- Rail infrastructure
- Ballast stabilisation
- Weak formation treatment
- Maintenance and rehabilitation projects
PAVEMENT SEALING AND CRACK CONTROL
Pavement sealing products help protect pavement integrity by preventing moisture ingress and reducing premature deterioration. They are commonly used in road construction, maintenance and rehabilitation projects.
Typical applications include:
- Asphalt joints
- Crack sealing
- Pavement maintenance
- Road rehabilitation

FUNCTION
Barrier
Prevents or reduces the movement of any fluid through the use of a geosynthetic barrier. Used to isolate one material from another. Common applications are landfills or ponds to prevent contamination of surrounding areas.
Containment
Geosynthetics acts as a relatively impermeable barrier to liquid or gases. Geotextile composites and geosynthetic clay liner (GCL’s) can be used as barriers to impede flow of liquid or gases. Also used in asphalt pavement overlays and waste containment.
Drainage
Geosynthetics can act as a drain to carry fluid through less permeable soils. Ideal for use in subsoil drainage systems, can be used to dissipate pore water pressures at the base of road and railway embankments, sports fields and behind retaining walls. Facilitates surface water runoff.
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.
Protection
Geosynthetics can prevent acute damage caused by adjacent materials. Often used together with a barrier to ensure that surrounding areas will not be contaminated. Widely used on landfills, tunnel construction and dams.
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.
