The geomembrane currently used in our country is mainly high-density polyethylene geomembrane.

The selection of geomembrane should be comprehensively considered in terms of engineering application, economy, construction technology characteristics and material performance. First consider whether the permeability and quality meet the requirements. Secondly, in order to prevent damages encountered during transportation and construction, geomembrane must have good mechanical properties such as anti-permeation, anti-puncture, and tensile strength. Of course, during construction, we must also take care to protect it from damage. In addition to the above points, durability and thickness should also be considered.

Impermeable geomembrane is made according to national standards and special requirements, and it has advantages different from ordinary impermeable membranes.

1. Excellent environmental adaptability: Most of the traditional geomembrane materials have a single performance, and there are not many methods that can be used.

Waterproof geotextile is a type of geosynthetic waterproof coating made of polyethylene as a waterproof substrate and geotextile.

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.
