We produce geomembrane liners. And geomembranes are manufactured to meet or exceed the test values. Can meet the GRI GM13 /GM17 specification which was established by Geomembrane Research Institute (GRI), USA. The frequency of testing & functional requirements of the GRI GM13 /GM17 specification which was established by Geomembrane Research Institute (GRI), USA.

The majority of generic geomembrane test methods that are referenced worldwide are by the American Society of Testing and Materials (ASTM) due to their long history in this activity. More recently, are test method developed by the International Organization for Standardization (ISO). Lastly, the Geosynthetic Research Institute (GR) has developed test methods that are only for test methods not addressed by ASTM or ISO. All three organizations have websites from which such appropriate standards can be obtained. Of course, individual countries are individual manufacturers often have specific (and sometimes) proprietary test methods.

we are manufacture with near 20 years experience on geomembrane and geotextile.

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.

For all types of welding, the Installer Site Manager shall verify that the welding personnel are attentive and act professionally and all equipments are well maintained and functioning properly. Welding Technician must purge the Extruder machine of heat degraded extrudate for at least one minute prior to use. The surfaces to be welded are well abraded and clean.

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 welded by Fusion Weld method using a self-propelled hot air or hot wedge welding machine. The welder creates a fusion weld by heating the overlapped liner surfaces, with a pair of pressure rollers pressing them together while in molten state to result in a permanent bond. Seam overlap shall be consistent with the requirements of the welding equipment being used. For fusion weld a 4 inch (100 mm) overlap is a common standard.

Generally, seams are oriented parallel to the direction of maximum slope. Seams are minimized in corners, odd-shaped geometric locations and outside corners. A seam is considered a separate entity if it is the principal attachment that joins two or more panels.

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.) .
