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
SpecLinerHD: current specification
The following summary is taken from KHDPE-GM13 Revision D, 23 September 2026. It covers smooth black sheet specified to GRI-GM13 Revision 19, Table 1(b). Values are specification requirements; production-lot certification and manufacturing quality-control reports support supplied-material conformance.
| Item | Specified requirement or format |
|---|---|
| Nominal thicknesses | 1.0, 1.25, 1.5, 2.0, 2.5 and 3.0 mm |
| Nominal widths | 7.5 or 8.0 m; confirm usable width for the selected line |
| Roll lengths | Made to order, subject to production, roll mass and handling constraints |
| Manufacture | Blown film is the current standard; flat die available by request |
| Stress-crack resistance | ASTM D5397 Appendix SP-NCTL: ≥500 h |
| Initial oxidative induction time | Standard OIT ≥100 min OR HP-OIT ≥400 min |
| Oven ageing: retained OIT after 90 days at 85°C | Standard OIT ≥55% OR HP-OIT ≥80% |
| UV: retained HP-OIT after 1,600 h | HP-OIT ≥50% |
| Kontain EdgeProtect™ | Standard on every roll: upper face of one long edge and underside of the opposite long edge; peel away before welding |
| Core options | Cardboard or weatherproof, recyclable plastic; confirm dimensions and handling requirements |
| Release records | Certificate of conformance, production-lot MQC reports and roll traceability |
Plan roll widths and lengths around installation
The standard width options are 7.5 and 8.0 m. Roll lengths are customisable so the order can reflect panel layout, seam locations, site access, lifting limits and freight. For other width requirements, ask Kontain to confirm a suitable manufacturing route.
Welding rod with matching resin and ConcreteLockPE concrete embedment profiles can be supplied. Confirm rod diameter, profile geometry, penetrations and the installation details before ordering.
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.
ConcreteLockPE: weld the liner to a cast-in concrete profile
ConcreteLockPE is Kontain’s polyethylene concrete embedment profile, supplied from Inno. Its anchor ribs are cast into fresh concrete, leaving the flat polyethylene face exposed. The installer then extrusion-welds the compatible HDPE liner to that face, forming the designed liner-to-concrete connection.
Use it at concrete walls, channels, sumps, pits and other liner terminations where a cast-in weldable connection is required. Position and restrain the profile before the pour, consolidate concrete around the ribs and keep the weld face clean. Prepare and qualify the extrusion weld under the project procedure.
- Dimensions are based on the supplied Inno profile diagram; confirm tolerances and the order drawing before manufacture.
- Profile joints, corners, concrete embedment, weld compatibility, movement and loads require project detailing. No pull-out capacity or pressure rating is declared here. The profile is a separate accessory; the geomembrane’s GM13 requirements do not certify the profile.
| Item | Standard format |
|---|---|
| Overall width | 150 mm |
| Overall height | 30 mm |
| Base thickness | 5 mm |
| Length | 3 m per piece |
| Bundle | 10 lengths = 30 linear metres |
Higher SCR, durability and surface options
Where the application needs more than the standard smooth black grade, Kontain can source enhanced stress-crack resistance and stabiliser packages against agreed requirements. Set the required test values and obtain evidence for the offered formulation.
White or coloured surfaces, conductive constructions and textured HDPE require their own variant data or specification. The smooth black Rev D values must not be transferred to those products without verification.
Select the complete HDPE lining system
Review chemistry, operating temperature, exposed or covered service, ground movement, slope interfaces and construction loads. Protection geotextiles, drainage layers, anchors, ballasting, penetrations and field seams all contribute to the installed system.
Kontain can prepare the agreed liner design inputs and drawings, coordinate material supply and organise installation quotations. Independent production-line sampling and testing through TRI in China can also be arranged at additional cost, with scope and timing agreed before manufacture.
Practical questions
Is SpecLinerHD a high-SCR grade?
The standard smooth black Rev D specification requires SP-NCTL stress-crack resistance of at least 500 hours. Enhanced grades can be sourced to a separately agreed requirement supported by evidence for the exact formulation.
Does the TDS certify every supplied roll?
The TDS states the product specification. The ordered material is supported by its production-lot certification, MQC reports and roll register. Independent testing applies to the sampled material and tests performed.
What warranty is available for an HDPE liner?
Available warranty terms are confirmed for the selected grade, application, exposure and agreed supply scope. Request the proposed terms with the material quotation; installation workmanship cover is addressed separately where installation is quoted.
