Introduction of Geomembrane
Geomembrane is a kind of impervious material which is made up of plastic film as impervious material and non-woven fabric. The anti-seepage performance of the new material geomembrane is mainly determined by the permeability of plastic film. At present, the domestic and foreign application of impervious plastic film, mainly polyvinyl chloride (PVC) and polyethylene (PE), EVA (ethylene / vinyl acetate copolymer), using the ECB design and application in tunnel (ethylene vinyl acetate modified asphalt blending geomembrane), which is a kind of high chemical flexible material, a smaller proportion extension, strong adaptability of deformation, high corrosion resistance, low temperature resistance, frost resistance.

Geomembrane is a kind of waterproof barrier material based on polymer. Mainly divided into: low density polyethylene (LDPE) geomembrane, high density polyethylene (HDPE) geomembrane and EVA geomembrane.
1 width and thickness specifications.
2 excellent resistance to environmental stress cracking and excellent chemical corrosion resistance.
3 excellent chemical resistance.
4 has a larger operating temperature range and longer service life.
5 used in landfill, tailings storage, seepage control, seepage control and subway project.

The main mechanism is a plastic film impermeable partition dam Water Leakage channel, with its large tensile strength under pressureadapt to dam deformation; and the non-woven fabric is also a kind of polymer material chemical short fiber, through acupuncture or thermal forming, with tensile strength and elongation is higher, it is combined with after the plastic film, not only increases the tensile strength and puncture resistance of plastic film, non-woven fabric and because rough surface, increases the friction coefficient of the contact surface, in favor of composite geomembrane and protection layer stability. At the same time, they have good corrosion resistance to bacteria and chemical action, not afraid of acid, alkali, salt erosion, in the light of the use of long life.

The properties of HDPE geomembrane are as follows:
1. HDPE geomembrane is a kind of flexible waterproof material, which has a high coefficient of seepage control (1 * 10-17 cm/s);
2, HDPE geomembrane with good heat resistance and cold resistance, the use of the ambient temperature of 110 degrees high temperature, low temperature -70 c;
3, HDPE geotechnical membrane has good chemical stability, corrosion resistance to acid, alkali, oil is good anticorrosive material;
4, HDPE geomembrane with high tensile strength, so that it has a high tensile strength to meet the needs of high standard engineering projects;
5, HDPE geomembrane has a strong weather resistance, has a strong anti-aging performance, can be used for a long time exposed to maintain the original performance;
6, the overall performance of HDPE geomembrane, HDPE geomembrane has a strong tensile strength and elongation at break, so that the HDPE geomembrane can be used in a variety of different geological and climatic conditions. To adapt to the uneven settlement of geological strain;
7, HDPE geomembrane with high quality original plastic and carbon black particles do not contain any preservatives, HDPE has been used in our country to replace PVC as food packaging bags and plastic film raw materials.

Main application 
1, HDPE geomembrane suitable for environmental protection, sanitation: such as landfill, sewage treatment plant, power plant regulation pool, industrial, hospital solid waste, etc.;
2, LDPE impervious membrane applied to water conservancy project such as seepage, riverslakes reservoir dam reinforcement, plugging, anti-seepage of canal, vertical wall, slope protection;
3, HDPE impervious membrane in Municipal Engineering: subway, building underground engineering, planting roof, Roof garden, sewage pipe seepage control;
4, polyethylene film for Garden: artificial lake, river, reservoir, golf course pond bottom, slope protection and greening lawn waterproof etc.;
5, high density polyethylene geomembrane for petrochemical: chemical plant, refinery, oil tank seepage control, chemical reaction pool, sedimentation tank lining, the two lining, etc.;
6, polyethylene geomembrane for heap leaching mining: washing pool, pool, Ashery, dissolved pool, sedimentation tank, yard, the bottom lining seepage of tailings;
7, low density polyethylene film for transportation facilities: highway foundation reinforcement, culvert seepage control;
8, LDPE impermeable membrane suitable for agriculture: reservoir, drinking water pool, water storage pond, irrigation system seepage control;
9, HDPE film for aquaculture: intensive factory farming, pool, pond, pond liners, sea cucumber ring protection;
10, high density polyethylene film for salt: saltern crystallizer ponds, pond, salt, brine cover film Yanchi plastic tarpaulin film.

Construction method
 Geomembrane in the process of transport do not drag, hard pull, to avoid sharp stab wounds.
1, should be extended from the bottom to the high, do not pull too tight, should be left with more than 1.50%, in order to prepare for local sinking. Taking into account the actual situation of the project, the slope from top to bottom laying order;
2, two adjacent longitudinal joints should not be in a horizontal line, should be staggered over 1m;
3, the longitudinal distance of the foot, bending at the joints should be more than 1.50M, should be located in the plane;
4, the first slope back bottom;
5. When the slope is laid, the direction of the film should be parallel to the maximum gradient line.

Laying precautions
1 prior to the laying of geomembrane should be the civil engineering acceptance certificate.
2 geomembrane before cutting, should be accurate measurement of its related dimensions, and then according to the actual cutting, the general should not be cut according to the size of the icon, should be a serial number, detailed records on the special form.
3 laying geomembrane should strive to weld the least, in the premise of ensuring quality, try to save raw materials. At the same time also accommodate
Easy to ensure quality.
4 the overlap width between the membrane and the membrane is generally not less than 10cm, which usually makes the alignment direction parallel to the maximum gradient.
5 normally in the corner and abnormal area, should be as far as possible to shorten the length of the joint. In addition to special requirements, the slope is greater than 1:6 on the slope away from the top slope or stress concentration area within 1.5 meters, as far as possible without welding.
6 geomembrane in the laying, should avoid artificial folds, when the temperature is low, should be taut, smooth.
7 geomembrane laying is completed, should minimize walking and handling tools on the membrane surface, which can cause harm of the objects on the membrane, shall not carry it or walk on the membrane in the membrane, so as to avoid accidental injury of membrane.
