A landfill liner system must coordinate containment, filtration, leachate collection, gas drainage and slope stability throughout the facility lifecycle. Park geosynthetic systems support base lining, landfill capping, drainage continuity and carefully engineered vertical expansion where available airspace is limited.
Discuss your projectClosure caps must manage infiltration, gas, erosion and long-term settlement as a coordinated layered system. Park reinforcement and drainage materials stabilise cover soils, preserve barrier interfaces and protect demanding side slopes.
Collection performance can decline as drainage media clogs, waste settles and hydraulic conditions change. Park drainage, filtration and reinforcement layers maintain defined liquid pathways, protect the liner and support reliable collection over the operating life.
Recovering airspace above existing cells requires controlled loading, reinforced slopes and protected containment interfaces. Park systems support staged vertical growth while managing settlement, stability and drainage inside a constrained footprint.
LANDFILL LINER FAQ
Depending on the approved design, landfill systems may use geomembranes as barriers, geotextiles for filtration and protection, geocomposite drainage layers for liquid or gas flow, and geogrids or high-strength geotextiles for reinforcement. Each material must be selected as part of the complete engineered system.
A drainage geocomposite combines a flow-transmitting core with one or more geotextile filter layers. It can convey leachate toward collection pipes and sumps while limiting the migration of adjacent soil fines, subject to project-specific flow and loading checks.
A geotextile may provide filtration, separation or cushioning protection. Protective nonwoven geotextile layers are commonly considered around geomembranes where the design must reduce puncture risk from the subgrade or overlying drainage material.
A final cover may coordinate a barrier layer, drainage layer, reinforcement, cover soil and erosion protection. Geosynthetics help manage infiltration, gas, settlement, interface stability and surface runoff when specified as an integrated cap system.
Slope geometry, waste settlement, cover-soil loading, water pressure, interface shear strength, drainage and anchorage all affect stability. These conditions require project-specific geotechnical design and verification.
