GeoQ Products
At GeoQ, our array of geosynthetic products is curated to meet the diverse needs of Australia’s construction and environmental management sectors.
Our portfolio includes a comprehensive selection of liners, geomembranes, geotextiles and other geosynthetic products essential for ensuring the structural integrity and durability of a wide range of infrastructure projects.
Each product is chosen for its quality, performance and ability to meet stringent industry standards, reflecting our commitment to providing materials that not only serve their purpose but also contribute to the longevity and safety of the projects they’re a part of.
HDPE
GeoQ’s High Density Polyethylene (HDPE) geomembranes, ranging from 0.75mm to 3mm in thickness with options for smooth or textured finishes, are expertly fusion-welded to create a robust, fully impermeable lining system.
Ideal for environmental containment, these HDPE solutions are pivotal in applications such as Brine Storage Ponds and Landfill Cell Linings, ensuring protection of groundwater by exceeding the stringent GRI GM13 specification.
LDPE & LLDPE
GeoQ offers LDPE (Low Density Polyethylene) and LLDPE (Linear Low Density Polyethylene) geomembranes, which share similar properties with HDPE but provide enhanced flexibility, allowing for folding and adaptation to varied shapes.
While not as resistant to chemicals or UV as HDPE, these materials are often utilised for Potable grade applications and are the preferred choice for fabricating floating covers.
GCL
GCL (Geosynthetic Clay Liner) features a core layer of Sodium Bentonite/Montmorillonite securely sandwiched between two geotextile fabrics, providing a self-sealing, low-permeability barrier.
While it can be deployed as a primary liner under earth backfill, it is most commonly utilised as a reliable secondary liner beneath HDPE or other primary geomembranes, enhancing leak protection in containment systems.
Geotextile
GeoQ’s geotextile material range, available in both woven and non-woven options, offers versatile filter cloth solutions in multiple grades and thicknesses to suit different project needs.
Commonly employed as a protective underlay beneath geomembrane liners or as a cushioning overlay to safeguard against drainage aggregate in landfills, geotextile material also serve as an efficient filtration layer on either side of a HDPE Geonet.
Geocomposite
Our geocomposite products integrate the filtration properties of geotextiles with the drainage capabilities of Geonets, forming a cohesive liner system, such as a non-woven Geotextile encapsulating a Drainage Net.
This design allows the geotextile to effectively filter out silt and clay particles, preventing clogging and making it ideal for use underneath liner systems in contact with soil or CCL subgrades for optimal groundwater management.
CSPE
GeoQ specialises in the application and quality assurance of CSPE geomembranes, delivering durable containment solutions across mining, civil and environmental sectors.
With expertise in Electrical Leak Detection (ELD), Construction Quality Assurance (CQA) and Destructive Testing, we ensure CSPE linings provide superior UV resistance, chemical durability and long-term performance for tailings storage, reservoirs, landfills and critical infrastructure projects worldwide.
Bituminous Geomembrane
Bituminous Geomembranes (BGMs) are emerging as a versatile alternative to traditional HDPE liners, extensively applied across industries and mining for water storage, lagoon systems, and containment of liquid and solid wastes, including landfills with bottom ash and composts.
GeoQ leverages its expertise to guide clients on the selection of BGM products and ensures quality installation, with BGM seams expertly welded by technicians using an LPG Blow torch to fuse the material layers for a secure and durable bond.
