Geomembrane is a kind of polymer as the basic raw materials waterproof barrier. Divided into: low density polyethylene (LDPE) geomembrane, high density polyethylene (HDPE) geomembrane and EVA geomembrane. Geomembrane characteristics: Width 6 m water impermeable membrane, is currently the most wide-composite film high puncture resistance, friction coefficient good aging resistance, adapt to the environment temperature range excellent resistance to drainage performance suitable for water, chemicals, construction, transportation, subways, tunnels, waste disposal sites and other projects HDPE geomembrane performance characteristics are as follows: 1, HDPE geomembrane is a flexible waterproof material, with high seepage coefficient (1 × 10-17 cm / s); 2 , HDPE geomembrane has good heat resistance and cold resistance, the use of ambient temperature of the high temperature 110 ℃, low temperature -70 ℃; 3, HDPE geomembrane has good chemical stability, resistant to acid, alkali, oil, corrosion is a good anti-corrosion materials; 4, HDPE geomembrane with high tensile strength, it has a high tensile strength to meet the high standards of project needs; 5, HDPE geomembrane has a strong weather resistance, there are Strong anti-aging properties of low-water impermeable membrane, can use for a long time exposed to maintain the original performance; 6, the overall performance of HDPE geomembrane practical waterproof impermeable membrane, HDPE geomembrane has a strong tensile strength and elongation at break rate, so HDPE geomembrane can be used in a variety of adverse geological and climatic conditions. Adapt to uneven settlement of Geology strong strain; geomembrane construction methods do not drag in the transport process, pull hard to avoid sharp objects stabbed. 1, the bottom should be extended to high, do not pull too tight, should leave more than 1.50% of the increase, to prepare for local subsidence stretch. Taking into account the actual situation of the project, from top to bottom of the slope to take the laying sequence; 2, two adjacent longitudinal joints should not be the latest waterproof impermeable membrane in a horizontal line, should be staggered over 1m; 3, vertical joints should be away from the dam feet, legs bent at 1.50m above, should be located in the plane; 4, the first after the end of the slope field; 5, when the slope laying show the film to be substantially parallel to the direction of maximum slope line. Composite geomembrane structure from the base surface, geomembrane, a protective layer, stone (or concrete) a total of four layers slope of the best waterproof impermeable membrane, Florida water impermeable membrane, Edison new materials (View) new material provided by the Edison Company.
