EdgeProtect™
Less cleaning. More time welding.
Removable weld protection film on every SpecLinerHD and SpecLinerLLD roll. Keep the mating weld faces protected during handling and deployment, then peel the film away immediately before welding.
No residue left behind after removal.

Less seam cleaning
Helps keep dust and loose debris off the weld zone, reducing repeated wiping before welding.
Both mating faces protected
Film on the upper face of one long edge and the underside of the opposite long edge.
Included on every roll
Standard across Kontain SpecLinerHD GM13 HDPE and SpecLinerLLD GM17 LLDPE.
On site
Protect. Peel. Weld.
- Deploy and alignLeave both strips in place while positioning the panels so the protected faces meet at the overlap.
- Peel both stripsRemove the upper-face and underside films completely just ahead of welding. Collect the used film as you go.
- Inspect, then weldCheck for clean, dry faces, complete final preparation and weld under the qualified procedure. Trial welds and project seam testing still apply.
Cut edges, roll ends and repairs need normal seam preparation.

Technical details
Where LLDPE belongs in the options review
LLDPE is an option where flexibility and conformity to the prepared surface are important. Applications may include covered containment, landfill caps, ponds and civil lining details, subject to the project’s exposure and deformation assessment.
Material selection considers the magnitude and distribution of movement, penetrations, anchorage and protection. A flexible liner still needs a suitable foundation, verified seams and an appropriate chemical and durability basis.
SpecLinerLLD: GM17 technical data
The SpecLinerLLD Revision A TDS, dated 23 September 2026, specifies smooth black LLDPE against GRI-GM17 Revision 17, Table 1(b). It states specification requirements, not batch test results. Confirm the offered thickness, roll schedule and production-lot evidence before supply. Textured and other variants require their own data.
- Confirm thickness, mechanical properties and multiaxial response for the proposed deformation.
- Specify antioxidant, ageing and UV requirements appropriate to exposed or covered service.
- Assess chemical compatibility and temperature using evidence relevant to the stored liquid and conditions.
- Match interface shear, puncture protection and seam qualification to the complete lining profile.
Smooth, textured, coloured and custom formats
Blown-film and flat-die sourcing options can be investigated with custom widths and lengths. Smooth, single-sided or double-sided textured, embossed and other textured surfaces can be considered for the proposed interfaces.
White, coloured and specialist constructions require confirmed variant and layer-specific data. Manufacturing availability, usable width, roll mass, minimum quantities and programme are confirmed for the offered grade.
Cardboard or weatherproof plastic cores
Customise the roll core to suit storage, lifting equipment and site handling. Cardboard and plastic cores are available. Plastic cores are weatherproof and recyclable through a suitable plastics recycler, subject to local acceptance and contamination limits.
Confirm the core material, internal diameter, wall thickness, roll mass and lifting arrangement with the order. Keep cardboard cores dry and store all rolls securely, protected from mechanical damage.
Coordinate LLDPE with GCL, protection and drainage
Where a composite barrier is specified, review the LLDPE together with the GCL or other low-permeability layer. Contact conditions, cover, hydration, liquid compatibility, seams and penetrations affect the system.
Laminated LLDPE/GCL constructions require data and installation details for the actual laminate. A standalone geomembrane data sheet does not automatically qualify a laminated product. Kontain can help assess these interfaces and prepare the agreed material schedule.
From liner selection to a coordinated quotation
Send the plan, quantity, proposed thickness, contained material, expected movement and delivery programme. Identify whether you need material supply, liner selection, anchor-trench or ballasting drawings, drainage assessment or an installation quotation.
We develop the sourcing options and confirm the proposed product, evidence, delivery programme and available application-specific warranty terms in the quotation.
Practical questions
Should I specify HDPE or LLDPE?
Compare both against the chemistry, temperature, deformation, exposure, interfaces and installation conditions. LLDPE’s flexibility can be useful, while the full product and system requirements determine the selection. Kontain can help develop that comparison.
Can I use the SpecLinerHD data for LLDPE?
No. The SpecLinerHD Rev D TDS covers smooth black HDPE. Use the separate SpecLinerLLD GM17 TDS and the production-lot evidence for the supplied LLDPE grade.
Can you provide textured LLDPE and installation quotes?
Yes. Kontain can source textured LLDPE options and organise installation quotations. The offered surface, interface testing, fabrication details, site scope and programme are confirmed for the project.
