Sew knit polyester cloth before application and waterproof layer, should check the current status of the roof at the grass-roots level to ensure that the roof with no moisture, no freezing, smooth and clean, no loose grain protrusion, even other blocking some impurities, waterproof system of the cohesive force for don't need the waterproof work must carry on the protection of areas, use brush, broom to clean up the surface dust, Or other loose attachment, for the corner, gap joints, water outlet, out of the pipeline need to apply waterproof system, the need for separate treatment work in advance, the use of a layer of basic coating to add appropriate size of stitched polyester cloth to add a layer of basic coating, Next, I will talk to you about the construction process of sewing polyester cloth to help you have a deeper understanding of sewing polyester cloth.

Geomembrane is a flexible geosynthetic impermeable material, and the stability of its underlying support layer is one of the keys to the safety of geomembrane. If the underlying support layer has obvious uneven deformation and local erosion, the geomembrane will be partially torn, forming a leakage channel, threatening the safety of the project.

The composite geomembrane has high flexibility, and has excellent chemical and physical properties. These functions will help materials overcome various difficulties in different production areas and provide more feasible suggestions for industrial projects.

The key to ensure the anti-seepage of composite geomembrane lies in the integrity and tightness of the placed materials. When constructing composite geomembrane, you need to smooth the surface of the base layer excellently. After the welding construction is completed, the construction quality inspection will be strengthened, and the damage will be repaired in time.

The main function of using composite geomembrane in water-saving projects is to improve the anti-seepage effect of the entire project. From this perspective, the overlap of geomembrane is very important.
