A Liner That Grips the Slope

A textured surface can improve shear resistance against adjacent soil or geosynthetics. The resulting stability depends on the complete lining system, groundwater and loading; texture alone does not prevent sliding.

Rough surfaces can increase interface shear resistance
Steep-slope use requires project-specific stability verification
Same HDPE material and same test standards as our smooth liners

How Thick Should You Go?

Specify thickness from the applicable requirements, chemical exposure, hydraulic head, subgrade, protection and installation loads. The examples below are distinct procurement and design cases.

US municipal landfill HDPE60 mil1.524 mm minimum in the prescriptive composite option of 40 CFR 258.40; confirm all applicable requirements

Mining and deep reservoirsBy designEvaluate abrasion, loading, chemistry and protection; 2.0 mm is an option to assess, not a universal minimum

Ponds and gentle slopesBy designA gentle slope alone does not establish the required thickness or permit use of the lightest grade

Send the approved design for a written product proposal; final engineering acceptance remains with the project designer.Ask an engineer

Single-Sided or Double-Sided?

Both run on the same lines and meet the same GRI-GM13 base standard. The difference is simply which faces are rough.

Single-Sided Textured

Grip below, smooth above

The design specifies the rough-face orientation and acceptable movement at the smooth interface. Do not assume the cover layer can slide safely; both interfaces need assessment.

Landfill base slopes and side walls
Reservoir banks with soil cover
Any design that needs grip on one side only

Double-Sided Textured

Grip on both faces

Used where the design requires textured interfaces above and below the liner. Neither a 3:1 gradient nor double-sided texture proves that the full lining system is stable.

Landfill caps and closure slopes

Why Engineers Specify Textured

Interface resistance is one part of slope design. Engineers also evaluate subgrade stability, pore pressure, cover loading and the required factor of safety.

Test the Actual Interface

There is no universal 30° friction angle. Use interface shear tests with the proposed materials, normal stresses and moisture conditions; consider peak and large-displacement resistance.

Check 2:1 Slopes

A 2:1 (H:V) slope is approximately 26.6°. A 0.40 mm texture height is a manufacturing property, not evidence that this slope will remain stable.

Design the Complete System

Any increase in storage capacity must follow a verified stability design, including drainage, anchorage and construction tolerances.

Five Quality Checks to Confirm in Your Order

Resin Check

Confirm resin identity, density and melt-flow requirements against the agreed formulation. Any permitted manufacturing rework must comply with the order specification; post-consumer material is excluded under GM13.

Texture Control

The bump height is set per order — at least 0.40 mm — and measured per ASTM D7466.

Core Thickness Checks

For textured sheet, specify ASTM D5994 core-thickness measurements and the required average and individual limits. Any tighter tolerance needs written confirmation and supporting inspection records.

Test Methods and Frequency

Specify texture, tensile, stress-crack and OIT requirements with their applicable methods and frequencies. Long-duration and formulation tests are not automatically performed on every roll or batch.

Traceability Records

Request roll identification, corresponding quality records and the agreed sample-retention period. Confirm the records supplied with the order and the process for later enquiries.

Smooth Edges Make Welding Simple

Specify the smooth welding-edge width in the order; 150 mm can be assessed as a proposed detail. Edge preparation, overlap and welding procedure must suit the actual product and equipment. A smooth strip alone does not prove seam integrity.

Prepare the Ground

Prepare a smooth, firm surface without protruding stones or roots. Specify the compaction test method, target density and moisture range in the earthworks design; “90%” alone is not an acceptance specification.

Overlap the Edges

A 100–150 mm overlap may be considered during planning, but use the approved width for the actual sheet and welding equipment. Keep the weld area clean and align the specified smooth edges.

Weld the Seams

Dual-track hot wedge welding for the long seams; extrusion welding for corners and repairs.

Jinseed in-house materials testing laboratory

Test Every Seam

For dual-track seams, use ASTM D5820 air-channel testing with pressure, stabilization time and allowable loss specified for the material and thickness. A 0.25 MPa / 5-minute test is only an example if approved in the project procedure. Extrusion seams require a suitable separate test.

Questions Buyers Usually Ask

Single-sided or double-sided textured — which one do I need?

Single-sided texture provides one rough and one smooth face; double-sided texture provides two rough faces. Selection and orientation depend on the materials at both interfaces and the stability analysis, not a universal 3:1 slope threshold. Send the layer arrangement and slope drawing for a product recommendation subject to the project engineer’s approval.

What texture height do you guarantee?

The specified texture height is at least 0.40 mm (approximately 16 mil), measured per ASTM D7466 and recorded in the order’s technical data sheet. GRI-GM13 distinguishes this manufacturing property from interface shear strength: a higher texture does not by itself establish a safe slope angle.

What thickness should a steep-slope project use?

Our metric range is 1.0–3.0 mm (approximately 39–118 mil). Under the prescriptive composite option in 40 CFR 258.40, HDPE must be at least 60 mil (1.524 mm); a nominal 1.5 mm grade is not automatically equivalent. Select thickness for the actual application, chemistry, loads, subgrade and protection, subject to the applicable requirements and project design.

What is your minimum order?

Trial orders start from 1-3 tons for regular specifications. For export shipments, a full container usually gives a better cost per square meter. Custom texture heights or roll sizes may need a larger minimum.

How long does production take?

Standard products are usually produced within 7-15 days after the specification and deposit are confirmed. Custom orders or peak-season schedules typically take 15-25 days. We confirm the delivery date before mass production starts.

Can we get test reports and samples before ordering?

Request the technical data sheet, available sample reports and the quality records required for your ordered grade. The published TRI SCH24132 report concerns one 2.0 mm smooth HDPE sample and does not certify all textured products. Confirm samples, shipping and any independent testing scope and costs before ordering.
