We have our own production of Needle punched  Geotextile, Geomembrane (water board), and Geogrid Composite Geomembrane ,  Acupuncture Geotextile annual 10 million square meters, Composite Geomembrane 2000 tons, three million square meters grille.

Is one ofChina's Association of geosynthetics, the former State Economic and Trade Commission geotextile material production enterprise focus. China Import and Export Fair preferred product enterprises, the State Flood Control Office of the designated company engaged in the production of Geotextile material and extension of many years of history and experience of products to meet international GB/T-17638-1998, GB/T-17639 -1998, GB/T-17462-1998, Shandong Province won the title of quality marks.
For several years, my company production of geotextile material, widely used in national and local large, medium and small water conservancy, electric power, railways, highways and other projects, the company adhere to the "quality first, reputation first" principle, in good faith with the people in the engineering sector cooperation.

The main products are as follows:

1). Staple fiber ( Polyester Stable Or Polypropylene fibre) non-woven acupuncture Geotextile:
Specifications of 80-1600g / ㎡ , The width can be to 8m, output of 22,000 ㎡ / day
2). Geomembrane
Geomembrane also known as film or a single membrane, membranes for PE. Specification :0.5-2 mm width: 2m-6m width 4m commonly used for reservoirs, tunnels, waste disposal and engineering field.
3), Composite geomembrane (also known as Composite Geotextiles or waterproof material): Specifications: a cloth of a membrane and two cloth one membrane. Membrane for PE or EVA, thickness 0.1-2 mm Specifications: a fabric of a film: If such 200/0.2 200/0.3 300/0.4 300/0.5.
Second Budd-film: If 150/0.3/150 200/0.3/200 200/0.2/200 300/0.3/300 and so on, cloth grams of weight and thickness in accordance with the specific design requirements for manufacture. Width of 4m-5m, production: 22,000 ㎡ / day
4), Filament Geotextile Booker heavy 100-1000g / ㎡ width 4m
5). Geogrid (glass or plastic, single two-way grille), Specification: T20, T30, T50, T80, etc

Composite Geomembrane construction method:
The status of construction workers because of different quality requirements of different construction methods combined with different habits, therefore, the construction method of composite geomembrane Geotextile in the light of the construction method at the same time, special attention on the construction issues and make recommendations reference joints.

1, construction NOTES:
(1) to be embedded: coverage of the thickness of not less than 750px
(2) refurbishment of anti-seepage system should be: layer, impervious layer, transition layer, the protection layers.
(3) of soil to a solid, to avoid uneven subsidence, cracks, seepage within the scope of grass, and roots to clear. Membrane contact with the laying of the small size of sand or clay for the protective layer.
(4) the laying of the time not to pull too tightly Geomembrane, buried in soil in part at both ends into a wavy better, especially with rigid material anchor should have a certain amount of flexibility.
(5) during the construction to avoid stones, heavy direct hit in the geomembrane, the best side of construction, laying edge film, edge covering layer of protection.
2, joints
(1) Composite Geomembrane joints treatment is the key to the construction process, a direct impact on the operational life of the project, as far as quality testing showed that the ideal thermal welding methods. (Also available for special glue then) heat welding method is the surface of PE Geomembrane-phase heat treatment to surface melting, and then through the pressure so that the integration into one,
(2) Geomembrane best laid along a certain direction, the two sides have set aside a certain Geomembrane PE and PET film is not adhesive layer, the laying of a good time to adjust to each unit geomembrane in order to facilitate the two modules Geomembrane welding. ,
(3) Geomembrane after laying, use sand bags down to wind action, edge seams request can not have dirt, moisture, dust and so on.
(4) to adjust the pre-welded seams good two side PE single film, so that a certain overlap of broadband, and the formation, no crease.
(5) welding, preferably with some experience of technical personnel welding, welding using special welding machine welding. To adjust the temperature and speed (also available adhesive access).
