Composite geomembrane is widely used in reservoir anti-seepage engineering. 　　（1）The use must be embedded: the covering thickness should not be less than 30 cm。 　　（2）The renovation anti-seepage system shall consist of: cushion layer, anti-seepage layer, transition layer and shelter layer...Read more »

As we all know, the main equipment for geomembrane production in China is divided into two types: laminating machine and film blowing machine. Of course, the equipment will become more and more advanced, and the geomembranes produced will be greatly improved in terms of visual, physical and chemi...Read more »

During the construction process, the climatic conditions should meet the requirements of composite geomembrane construction. Pay attention to these details during construction. If you encounter strong winds or rainy days above level 4, construction should generally not be carried out. Generally, ...Read more »

The intersection of the slope is the bend of the dam slope. The laying and welding of geomembrane are special circumstances. There are many blind ditches in the design at the intersection of the slope and the bottom of the reservoir area, which should be specially cut according to the actual situ...Read more »

For large-area geotextiles, double-seam welding machine is mainly used for welding, and some parts must be repaired and reinforced by extrusion welding machine. Geomembrane is qualified if it is laid strictly according to the requirements on the slope and plane joints Check that the bottom surfac...Read more »
