Engineered impermeable barriers designed specifically for Waste-to-Energy collection and radon/methane mitigation. Our LLDPE solutions provide superior multi-axial elongation for settling environments without compromising gas integrity.
Utilizing co-extruded textured geomembranes with consistent asperity heights (exceeding 0.25mm), we maximize interface friction angles to prevent veneer cover soil sliding on steep-wall containment structures.
We offer custom roll widths up to 8 meters (26ft). By reducing the number of required field seams by up to 25%, we minimize potential leak paths and significantly lower CQA (Construction Quality Assurance) costs on-site.
Our nitrogen-injected or spray-on texturing processes allow for precise single-sided or double-sided friction control. This ensures compatibility with diverse geotextile interfaces and specific soil shear strength requirements.
Every roll undergoes rigorous ASTM-certified testing for tensile strength, puncture resistance, and carbon black dispersion, providing full traceability from raw resin to the final engineering project.
ISO 9001:2015 Quality Management Our production facility implements a rigorous 100% traceability system, ensuring every roll of geosynthetics meets international mechanical and physical performance standards from raw material to dispatch.
ISO 14001 Environmental Protection We prioritize sustainable manufacturing processes. Our HDPE liners are designed for zero-leakage performance, specifically engineered to protect groundwater and ecosystems in high-risk environmental projects.

Standard and project-specific extended warranties backed by 20+ years of manufacturing excellence.
Expert insights on geosynthetic material specifications, engineering limits, and CQA installation standards.
Installed per GRI-GM13 standards and covered securely, our HDPE geomembranes are engineered to exceed 50 to 100 years. Standard OIT (Oxidative Induction Time) testing confirms exceptionally high resistance to oxidative degradation.
Yes. Our containment materials are formulated specifically to meet or exceed US EPA Subtitle D (40 CFR Part 258) criteria for Municipal Solid Waste (MSW) facilities, consistently maintaining a permeability rating of ≤ 1 x 10^-7 cm/sec.
All rolls are double-wrapped in high-strength, UV-stabilized woven geotextile jackets. We utilize strict container loading protocols (limited to 3 tiers) using industrial slings to prevent core crushing and pressure flattening during transit.
For our 2.0mm (80 mil) HDPE rolls, dual-track hot wedge welding temperatures typically range between 380°C and 420°C (716°F - 788°F), operating at speeds of 1.5 to 2.5 meters per minute, strictly depending on ambient field temperatures and humidity.
We conduct microscopic evaluation on every batch per ASTM D5596. Our advanced extrusion process ensures Carbon Black is uniformly dispersed at 2.0% - 3.0%, earning a Category 1 or 2 dispersion rating to guarantee maximum UV shielding over decades.
Absolutely. Our asperity-height textured series (ASTM D7466) provides an interface friction angle exceeding 28 degrees (varies by subgrade type), making them the ideal choice for side-slope applications up to 3:1 (H:V) ratios without sliding failure.
Yes. Our LLDPE (Linear Low-Density Polyethylene) formulations boast a multiaxial break elongation exceeding 800% per ASTM D5617 testing. This massive flexibility allows the liner to stretch and conform to severe localized subsidence without rupturing.
According to international CQA (Construction Quality Assurance) protocols, destructive samples for peel and shear strength testing (ASTM D6392) must be taken at least once every 150 linear meters (500 feet) of welded seam to mathematically guarantee watertight integrity.
