CETCO PRODUCT SELECTION + KONTAIN QUOTE
The result is a preliminary CETCO starting point and planning quantity. Kontain completes the technical review, confirms current product evidence, availability and freight, and issues the supply quote.
CETCO GCL SYSTEMS
Kontain provides the selection, Australian quotation and project technical support. Each quote nominates the exact CETCO product code, TDS revision and evidence required for the application.
Australian scrim-reinforced double-nonwoven GCL
General Australian containment where dimensional stability, a higher bentonite loading and strong peel resistance are useful.
The clearest current Australian general-purpose basis in the supplied CETCO data.
Australian scrim-reinforced double-nonwoven GCL
A lower-bentonite-mass DNW option where interface friction and dimensional stability matter and the project specification accepts the stated values.
Adds published CEC, montmorillonite and calcite controls to the supplied product data.
High-strength scrim-reinforced double-nonwoven GCL
Applications needing materially higher biaxial tensile strength, subject to project-specific internal and interface shear verification.
The supplied TDS certifies 14 kN/m minimum in both machine and cross-machine directions.
Needlepunched woven / nonwoven reinforced GCL
A high-tensile woven-carrier pathway where the specified interface and construction sequence suit the woven underside.
Publishes 12 kN/m MD tensile, AS 3706.4 CBR elongation and a 15 mL maximum fluid-loss value.
0.20 mm smooth PE-membrane-laminated GBR-C
Fresh-water ponds and liquid containment where a smooth integral PE laminate is preferred and the veneer interface is demonstrated as stable.
A 0.20 mm smooth PE membrane is laminated to the reinforced GCL; it is not a coating and it is not a welded geomembrane system.
1.0 mm double-sided textured PE-membrane-laminated GBR-C
Laminated liquid-containment systems where the smooth CL interface does not provide the required veneer stability.
The supplied TDS uses a 1.0 mm double-sided textured membrane with higher tensile and puncture values than CL.
North American reinforced woven / nonwoven reference GCL
A familiar CETCO reference product, but not the default Australian supply basis where an AU-specific DNW grade is nominated.
Retained as a published reference only. Confirm the actual factory, product code and current Australian supply TDS before quoting.
* CLT100 bentonite mass is reported at 12% moisture content in the supplied EMEA TDS; other dry-mass values are not automatically comparable. † ST internal shear is a typical peak at about 9.6 kPa normal stress, not a design envelope.
CETCO PRODUCT COMPARISON
Use this table to nominate a starting product. Kontain then checks current availability, project chemistry, interfaces and order-specific evidence.
FROM DESIGN BASIS TO SUPPLY
These six checks connect the product code to the liquid, liner profile, interfaces, installation method and evidence required for project acceptance.
Confirm whether the GCL is the mineral barrier, part of a composite liner or an integral PE-laminated system.
Choose the exact DNW, AS, CL, CLT or KGCL construction. Family names alone are not sufficient for specification or supply.
Fresh-water guidance does not transfer to saline, mining or industrial liquids. Kontain can coordinate compatibility testing with representative site liquids.
Use the actual cover soil and adjacent geosynthetics. A textured laminate can improve one interface, but all potential slip planes require review.
Panel orientation, overlaps, penetrations, hydration, cover and traffic controls must match the selected product and project drawings.
Kontain confirms the TDS revision, roll schedule, certificate of analysis, traceability and agreed project conformance testing before order release.
KONTAIN GCL ALTERNATIVES
KGCL-ST and KGCL-L are Kontain private-label products supplied with their own technical approval, order evidence and project conformance plan. They are not presented as CETCO products or automatic equivalents.
Kontain uncoated reinforced GCL
A value-engineered route for conventional, non-aggressive containment where the project accepts a defined order-evidence and conformance-testing plan.
Nonwoven upper face, sodium-bentonite core and woven underside. It is a Kontain product and does not inherit CETCO data or installation details.
Kontain laminated GCL range — 0.20, 0.50 and 1.00 mm
Integral PE-laminated containment where the exact laminate polymer, thickness, antioxidant evidence, interfaces and hydraulic duty are selected for the project.
The lower panel combines a 300 mm factory-unlaminated receiver overlap, a 500 mm powder zone at 400 g/lineal m (800 g/m²) and three lower-panel release/locking cuts beneath continuous upper-panel PE.
KGCL-L FACTORY LONGITUDINAL OVERLAP
The lower panel is mechanically impregnated with powdered sodium bentonite across a 500 mm factory zone at 400 g per lineal metre (800 g/m²). The zone covers the full 300 mm unlaminated receiver overlap and extends 200 mm inboard beneath the lower-panel laminate. The powder is embedded within the fibres and core—not applied as a loose surface treatment—while the GCL core remains granular.
The fully laminated upper edge is placed so its woven underside contacts the exposed lower-panel nonwoven.
The 500 mm zone is applied at 400 g/lineal m—equivalent to 800 g/m² across that width.
When hydrated and confined, embedded powder and granular core bentonite migrate upward through the lower receiver layer to the contact interface.
No site powder is added at a compliant factory longitudinal seam. At transverse or cut seams, powder is mandatory wherever the lower laminate remains.
This Kontain production detail combines a wider embedded powder reservoir, direct GCL contact and three lower-panel migration paths. The same mechanism can be specified for Kontain unlaminated, coated and laminated GCL families, subject to the product-specific TDS, manufacturing controls and project approval.
Production-embedded, not surface-treated. For transverse overlaps or cuts, apply site powder wherever laminate is retained.
Use the current product-specific KGCL TDS, installation guide, order certificate and agreed conformance plan. CETCO product values, seam details and installation instructions are not transferred to KGCL supply.
CETCO DESIGN EVIDENCE
The CETCO CL/CLT guide provides useful fresh-water pond evidence. Kontain applies it as product-specific background and confirms the project tests needed for Australian design.
CETCO reports large-scale BENTOMAT CL testing at 207, 413 and 620 kPa hydraulic pressure. The guide corrects laboratory seam length to field seam density. Appendix A gives 4.05 × 10⁻¹⁰ m³/m²/s total flow at the 207 kPa test point; Section 2.3.6 uses 4.17 × 10⁻¹⁰ m³/m²/s as its design value.
Still installation-dependentOverlap continuity, bentonite enhancement, confinement, wrinkles and end joints remain decisive.The guide reports indicative average peak/residual angles of 25°/23° for soil against smooth CL geofilm and 32°/25° against textured CLT membrane at low normal stress. Actual soils and interfaces must be tested.
CLT is not an automatic passInternal shear, the opposite interface, rapid drawdown, anchorage and toe conditions still govern.CETCO INSTALLATION GUIDANCE
Use the original CETCO guide for lifting, storage, subgrade, deployment, anchorage, seams, penetrations, repairs, cover placement and hydration. Kontain supports the contractor with product selection and project-specific installation review.
Download CETCO installation guide ↗Do not install in standing water or rain. Deploy only what can be covered; do not leave uncovered overnight.
Use an approved firm, smooth subgrade without abrupt changes, voids, standing water or damaging protrusions. Equipment controls are product and method specific.
Follow the CETCO product/detail schedule for longitudinal and end overlaps, supplemental bentonite, penetrations and patches. High-head CL/CLT details differ.
Place cover without dragging or tensile loading. The guide uses at least 300 mm final cover and maintains cover between equipment and the GCL.
PRELIMINARY VENEER STABILITY CHECK
This simplified infinite-slope calculation compares slope demand with an entered interface friction angle. Use it to decide whether BENTOMAT CLT100 and project-specific shear testing should be considered—not as a final design.
