Introducing the composite geomembrane into a film and a film, a width of 4-6m, a weight of 200 - geomembrane production workshop 1500g / square meter, tensile, tearing, bursting and other urban green defense Infiltration for you to introduce composite geomembrane is divided into a cloth and a film, two cloth and a film, width 4-6m, weight 200 - geomembrane production workshop 1500g / square meter, tensile, tearing, bursting and other urban greening Anti-seepage special anti-seepage film supply anti-seepage film with high physical and mechanical properties, high strength, good extension performance, large deformation modulus, acid and alkali resistance, corrosion resistance, aging resistance and good anti-seepage performance. It can meet the needs of civil engineering such as anti-seepage, isolation, reinforcement, anti-cracking and reinforcement in water conservancy, municipal, construction, transportation, subway, tunnel and engineering construction. Because it uses polymer materials and anti-aging agent is added to the production process, it can be used in unconventional temperature environments. It is often used for anti-seepage treatment of dams and drainage ditches, as well as anti-fouling treatment of waste yards.

2. Composite geomembrane construction Composite geomembrane construction picture Composite geomembrane is a geotextile on one or both sides of the film to form a composite geomembrane. The form has a cloth one film, two cloth one film, two film one cloth and the like.
The geotextile acts as a protective layer for the geomembrane, so that the anti-seepage layer is protected from damage. In order to reduce ultraviolet radiation and increase anti-aging properties, it is best to use the embedding method.
In the construction, firstly, the sand surface or the clay with a smaller diameter should be used to level the base surface, and then the geomembrane is laid. The geomembrane should not be stretched too tightly, and the soil embedded in the soil at both ends is corrugated. Finally, a layer of about 10 cm is layered with fine sand or clay on the geomembrane. A 20-30cm block stone (or ç ¼ prefabricated block) is placed as an impact protection layer. During construction, every effort should be made to avoid the stone directly on the geomembrane. It is best to carry out the construction of the protective layer while laying the film. The joint of the composite geomembrane and the surrounding structure shall be anchored by expansion bolts and steel strips. The joints shall be coated with emulsified asphalt (thickness 2mm) to prevent leakage.
The joint treatment of composite geomembrane is a key process that directly affects the anti-seepage effect. The general seaming method is: 1 lap joint: the lap width should be greater than 15cm; 2 heat welding: suitable for a slightly thick geomembrane substrate, the weld lap width is not less than 5CM. (Not recommended for bonding, long time water immersion Easy to open the glue, poor anti-seepage effect.)
According to many years of practice, the thickness of the geomembrane is not less than 0.25mm. If it is too thin, it may cause pores, and it is easy to be damaged during construction to reduce the anti-seepage effect. In the construction of geomembrane, special attention should be paid to the laying should not be too tight, not wrinkle, and the splicing should be firm. It is necessary to strictly follow the technical specifications and put together five quality guarantees such as preparation, laying, splicing, inspection and backfilling. Due to the good anti-seepage effect of the composite geomembrane, at present, the material is widely used in the construction of water-saving renovation and continuous construction projects in Baojixia Irrigation District, which has been widely praised by the design and construction units.
