High Density Polyethylene Geomembrane

Product Description

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

High Density Polyethylene（HDPE） Geomembrane Introduction

A High Density Polyethylene Geomembrane is manufactured with the highest quality resin specifically formulated for flexible geomembranes. A premium grade carbon black made by the world first-class carbon manufacturer, Carbot, is used that incorporates a fine particle size for enhanced resistance to UV radiation.

High density polyethylene geomembranes include series of products with double sides smooth, single- or double-sided textured surface which owns superior shear strength and the high multi-axial performance.

The manufacturing of HDPE geomembrane is made of premium virgin HDPE resin along with adequate carbon black, antioxidant and stabilizers to have superior mechanical properties and outstanding long-term resistance to aggressive chemical, environmental stress crack and UV radiation.

Yingfan HDPE textured geomembrane has not only the superior previous features but also provides excellent friction. It is ideally suitable for the slope lining solutions.

Feature and Advantage

1. Good physical and mechanic performance.
2. High tearing resistance, strong deformation adaptability.
3. Puncture-resisting, aging resisting, ultra-violet radiation, oil and salt, and corrosion resistance.
4. Good adaptability to high and low temperature, non-toxicity, long service life.
5. Complete width and thickness specifications.
6. Low cost with economic price and easy installation.

HDPE Geomembrane Specification

Our HDPE Geomembrane product specifications be produced and tested via GRI-GM13 standard, ISO standard, GB/T 17643-2006 standard or CJ/T234-2006 standard. Most of items of these standards can be seen as the following:

HDPE Geomembrane Application

HDPE Geomembrane smooth can be used in the main five applications including environmental, geotechnical, hydraulic, transportation, and private development applications.

Environmental Application: liners for waste liquids (e.g., sewage sludge), secondary containment of underground storage tanks,brine solutions, the aquiculture industry such as fish/shrimp pond, primary, secondary, and/or tertiary solid-waste landfills and waste piles, heap leach pads, and so forth.

Geotechnical Application: As liners for vertical walls: single or double with leak detection, as cutoffs within zoned earth dams for seepage control, as a barrier to vapors (radon, hydrocarbons, etc.) beneath buildings, as waterproofing liners within tunnels and pipelines, to control expansive soils, to control frost-susceptible soils, and so forth.

Hydraulic Application: As waterproof facing of earth and rockfill dams, roller compacted concrete dams, masonry and concrete dams, to form barrier tubes as dams, to face structural supports as temporary cofferdams, to conduct water flow into preferred paths, and so forth.

Transportation Application: to contain and transport liquids in trucks, to contain and transport potable water and other liquids in the ocean, beneath highways to prevent pollution from deicing salts, beneath and adjacent to highways to capture hazardous liquid spills, beneath asphalt overlays as a waterproofing layer, and so forth.

Private Development Application: to prevent infiltration of water in sensitive areas, as containment structures for temporary surcharges, to aid in establishing uniformity of subsurface compressibility and subsidence, as flexible forms where loss of material cannot be allowed, and so forth.

Installation Process

Ordinary installation process includes the listed items: earthwork prepration, panel placement, trial welds, geomembrane field seaming, seaming testing, defecting and repairing, anchoring.
