Technical specifications of HDPE geomembrane:
a) Density ≥ 0.94g/m²
b) Tensile Strength ≥25Mpa
c) Elongation at Break ≥ 550%
d) Right-angled Tear ≥ 110N/mm
e.)Puncture Strength ≥ 550N
f.) Permeability Coefficient ≤1.0xe-13g.cm/(cm2.S.Pa)
g.) -70oC Low Temperature Impact Brittle Property: good.
h.) Chemical Resistance: at 80oC, marinated in 5g/L Nacl for a long time, it will not erode or swell.

HDPE has excellent physical property. Such as temperature adaptability, property of welding, bearing climate, anti-erosion,anti-crack and anti-puncture.As the leakage material,therefore Particularly suitable for the construction of underground,mining,landfill,sewage or dregs disposal.

Tinhy flat surface HDPE Geo-membrane is produced from high-grade white color hdpe geomembrane resin produced by foreign and domestic large petrochemical enterprises by three-layer pressing and plastic formation technology and double layer pressing and rolling technology. The company is the only enterprise that uses the two technologies to produce Geo-membrane in the same industry. The company has plastic formation experience for more than twenty years, makes close cooperation with earthwork builder, makes continuous innovation, seeks perfection, and makes great efforts in providing the most reliable products to the customers.

The seam area shall be clean and dry, free of mud, moisture, dust, dirt, sand or debris and seam panels are overlapped properly for fusion welding. Seam surface area shall be abraded or grinded to rid of surface oxidation and tack weld for extrusion welding. Grinding is performed parallel to the seam and grinding marks shall not extend more than quarter inch outside the weld bead area. The Welding Technician shall ensure that wrinkles or fish mouths are minimized. During seaming, visual inspection and constant hand peel testing is practiced.

Special detail fabricating areas such as sumps, pipe penetrations, concrete structures, fittings and Accessories shall require Extrusion Weld process. Non-linear seams, roll ends, pipe penetrations, sumps, patches, corners or anywhere it is impractical to use a Fusion Welder are welded by Extrusion Weld method using an Extruder Resin or Extruder Rod Gun. This technique encompasses extruding molten resin between two geomembranes or at the edge of two overlapped geomembranes to effect a continuous bond. The extrudate rod or resin bead shall be made from similar type as the geomembrane.

Geomembrane liners are also used as floating covers or cappings onto wastes lagoons or sludge pits to reduce air pollution, foul smell and to control flies, rodents and pests. HDPE geomembrane floating covers may be utilized in tandem with a CDM bio-gas or methane gas collection facility to co-generate electricity or to flare.

The Application of HDPE geomembrane

1) Environmental protection sanitation (such as solid waste landfills, sewage treatment plants, power plants Chi-conditioning, industrial, hospital solid waste, etc.) .
2) Water (such as rivers, lakes and reservoirs of the anti-dam, plugging, reinforcement of the canal seepage, the vertical wall of the heart, slope protection, etc.).
3) Municipal Engineering (subway, on the ground floor of the building, planted roof, the roof garden of anti-seepage, sewage pipes lining, etc.).
4) Landscape (man-made lake, river, reservoir, golf courses reservoirs of the substrate, slope protection, green lawn of the waterproof moisture, etc.).
5) Petrochemical (chemical plants, oil refineries, gas storage tanks of the anti-chemical reaction tanks, sedimentation tanks of the lining, etc.).
6) Mining (washing and pool heap leaching, the ash-field, dissolved, precipitation, the yard, the tailings seepage substrates, etc.) .
