GEO COMPOSITES RANGE
Geo Composites products
and applications.
SELECTED SOLUTION
Landfills
Supports capping and lining systems by controlling infiltration, protecting liners and keeping drainage pathways clear.HOW THE SYSTEM WORKS
One layered product.
Multiple site functions.
A geocomposite brings two or more geosynthetic materials together as a single engineered layer. A permeable geotextile admits water and retains soil fines, while the open polymer core creates a continuous route for water or gas to travel toward a designed outlet.
This combined construction simplifies installation and can provide drainage, filtration, separation and protection without assembling several independent layers on site.
WHERE GEOCOMPOSITES PERFORM
Landfills
Supports capping and lining systems by controlling infiltration, protecting liners and keeping drainage pathways clear.
Leachate Collection
Channels leachate toward collection points while filtering fine soil particles that can restrict long-term flow.
Civil Works Drainage
Provides vertical or horizontal drainage beneath embankments, retaining walls and other structures.
Roadways & Pavements
Combines separation and subsurface drainage beneath pavement layers to reduce moisture-related distress.
Mining Operations
Manages process liquids and seepage in heap-leach pads, tailings areas and containment facilities.
Tunnels
Intercepts groundwater behind tunnel linings while filtering fines and lowering infiltration pressure.
Green Infrastructure
Controls stormwater in green roofs and bioswales while filtering particles from runoff.
Erosion Control
Filters sediment and stabilises the surface of slopes and riverbanks so vegetation can establish.
COMPOSITE CONFIGURATIONS
Built around the function
the site actually needs.
Drainage, containment protection and structural reinforcement require different layer combinations. One system should never be treated as a substitute for another.Drainage composites
Geonet–geotextile composites
A high-flow geonet core is laminated with a nonwoven geotextile filter on one or both faces. Water enters through the textile, travels laterally through the open core and reaches the designed outlet, while fine soil particles remain outside the drainage path.
CORE FUNCTIONS
Four functions.
Clearly defined.
Drainage
Water passes through the filter and moves through the core toward a pipe or outlet, relieving hydrostatic pressure around walls and buried structures.
Filtration
Selected pore size allows water through while retaining fines at the surface, protecting the core from progressive clogging.
Separation
The composite prevents fine subgrade from migrating into coarse fill, preserving layer integrity, bearing capacity and settlement performance.
Load distribution
The layered build can reduce local stress concentration as a secondary benefit. Where tensile reinforcement is required, Park pairs the drainage layer with a suitable geogrid.
SYSTEM INTERACTION
Why the layers must
work as one.
Geonet cores commonly provide approximately 80–95% internal void space, allowing much faster lateral flow than the surrounding soil. Capacity alone is not enough: the filter, core and bond must remain compatible under the project’s load and hydraulic conditions.
At the interface, friction between fibres, soil particles and larger aggregates helps resist sliding. That interaction supports stability in retaining walls, embankments and other loaded drainage applications.
