High density polyethylene geomembrane is our top product in our company and this industry. We provide this product to many well‑known companies such as Sinopec, Petro China, Mengniu corp., Yili Corp., Muyuan Group, etc.

High Density Polyethylene（HDPE） Geomembrane Introduction

HDPE geomembrane is produced with premium‑grade resin specially developed for flexible geomembrane applications. Premium carbon black supplied by world‑class supplier Carbot is added for excellent UV‑radiation resistance.

HDPE geomembrane covers smooth double‑sided, single‑sided textured and double‑sided textured types. Textured versions deliver superior shear strength and multi‑axial performance.

Manufactured from virgin HDPE resin blended with carbon black, antioxidant and stabilizers. It achieves outstanding mechanical indexes, long‑term resistance to aggressive chemicals, environmental stress cracking and UV exposure.

Yingfan textured HDPE geomembrane keeps all above advantages plus excellent friction performance, ideal for slope lining projects.

HDPE Geomembrane Application

Environmental: waste‑liquid liners, secondary containment for underground tanks, brine storage, aquaculture fish/shrimp ponds, municipal solid‑waste landfills, heap‑leach pads etc.

Geotechnical: vertical‑wall lining (single / double‑layer with leak‑detection), earth‑dam seepage cutoff, building vapor‑barrier against radon & hydrocarbon, tunnel/pipeline waterproof liner, expansive‑soil improvement, frost‑susceptible‑soil treatment etc.

Hydraulic: anti‑seepage facing for earth‑rockfill dams, roller‑compacted concrete dams, masonry‑concrete dams, temporary cofferdams, water‑flow diversion barriers etc.

Transportation: truck liquid‑container lining, offshore potable‑water containment, highway anti‑pollution liner against de‑icing salt, hazardous‑spill capture under highways, asphalt‑overlay waterproof underlayer etc.

Private Development: anti‑infiltration barrier for sensitive zones, temporary surcharge containment, subsurface‑compressibility adjustment, flexible anti‑loss structural formwork etc.

Installation Process

Standard workflow: earthwork preparation → panel placement → trial welding → field seaming → seam inspection & testing → defect detection & repair → anchoring & fixing.
