Construction of composite geomembrane The composite geomembrane is heated by far-infrared heating on one or both sides of the film, and the geotextile and the geomembrane are pressed together by a guide roll to form a composite geomembrane. With the improvement of the production process, there is also a casting process for composite geomembrane. The form has a geotextile one geomembrane, two geotextiles one geomembrane, two geomembrane one geotextile 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. The soil embedded at both ends is corrugated. Finally, a layer of 10 cm or so of a transition layer is laid on the geomembrane. A 20-30cm block stone (or 砼 prefabricated block) is placed as an impact protection layer. During construction, efforts 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 geomembrane and the surrounding structure should be anchored by expansion bolts and steel strips. The joints should be coated with emulsified asphalt (thickness 2mm) to prevent leakage. #geotextile #geotextiles #geomembrane #geotextil #nonwovengeotextile #geotêxtil #geotextilnotejido #geotêxtilnãotecido #geossintéticos #geosintéticos #géogrille #geogrelha #geomalla #geosynthetics #geomembrana #geomembrane #geogrid #geonet #GCL #geocomposite #geocomposites https://www.instagram.com/p/B3lbOm6lKJC/?igshid=1bniyhen68968
