Textured Liner

From a geotechnical engineering perspective, the choice dictates your system's interface shear strength. Single-sided textured liners are highly effective when you need strong frictional grip against the subgrade on a steep slope, but require a smooth top layer so that contained materials (like solid waste) can slide down and settle at the bottom of the cell. Double-sided textured liners are engineered for high-risk slope stability (often 3:1 or steeper). They maximize the friction angle on both sides, providing critical interlocking stability between the subgrade below and a cover soil, geonet, or non-woven geotextile layer above, effectively increasing the overall Factor of Safety (FS).

Based on decades of on-site construction experience, attempting to weld fully textured surfaces with standard hot-wedge welders frequently results in failed peel and shear tests. By manufacturing Jinseed liners with precision smooth edges, we eliminate the hazardous and time-consuming practice of contractors manually grinding down the texture on-site. This ensures the welder maintains direct, uniform contact with the membrane, resulting in an ASTM-compliant, 100% leak-proof thermal fusion seam while drastically cutting down project installation time.

We manufacture our textured liners in strict compliance with GRI-GM13/GM17 standards, offering thicknesses from 40 mil (1.0 mm) to 120 mil (3.0 mm). Selecting the correct thickness depends on hydraulic head pressure and subgrade aggregate puncture risk. For example, the US EPA standard for Subtitle D municipal solid waste (MSW) landfill base liners is typically 60 mil (1.5 mm). For highly abrasive mining operations or deeper reservoirs, 80 mil (2.0 mm) or higher is recommended. We encourage you to utilize our Free Consulting Service to consult directly with our certified engineers for project-specific thickness calculations.

Asperity height is the measurable texture protrusion that locks into the surrounding soil matrix, tested in our laboratory per ASTM D7466. We guarantee a minimum asperity height of ≥ 10 mil (0.25 mm) for our standard textured liners, which perfectly handles typical sloped containment. However, for severe, high-stress engineering designs (such as 2:1 gradients), our manufacturing lines can be calibrated to produce an aggressive asperity height of ≥ 16 mil (0.40 mm), providing the ultimate frictional grip required by rigorous geotechnical designs.

Trust in material longevity starts with the resin. We exclusively use 100% premium virgin HDPE and LLDPE resins—we never use recycled materials that compromise molecular integrity. To ensure decades of performance against UV degradation and highly corrosive leachates (pH 4-10), our formulation includes exactly 2% to 3% premium carbon black, along with advanced anti-oxidants. This results in an exceptionally high Oxidation Induction Time (OIT), ensuring the liner strongly resists environmental stress cracking (ESCR) even in fully exposed conditions.

Absolutely. Transparency is core to our operations. As an authoritative member of the International Geosynthetics Society (IGS), every roll we produce undergoes a strict Manufacturing Quality Control (MQC) process. We provide comprehensive, verifiable Technical Data Sheets (TDS) for your engineering submittals. Furthermore, we will ship free physical samples directly to your firm or laboratory so your engineers can verify the mil thickness, asperity height, and material flexibility firsthand prior to procurement.
