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.

The selection of composite geomembrane should be considered from the fields of engineering application, economy, construction process characteristics and raw material characteristics.

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.

When selecting the anti-seepage geomembrane, we must first establish our ordering purpose, for which place and what function is required for ordering the geomembrane. Knowing this, we can reasonably and effectively reduce the selection category.

The most important feature of geomembrane as an anti-seepage material is that it has a good anti-seepage effect. Therefore, it is widely used for external waterproofing of dams, reservoirs and other projects. Moreover, the construction technology is simple, the requirements are not high, the cost is low, and the waterproof effect is good.
