The villagers built a small earth-rock dam on the river. After years of use and operation, many problems and defects have appeared. After investigation, a leak was found at the top of the dam.

A one-kilometer-long diversion canal with an impermeable geomembrane was built. After tests, the head of the canal drained 1000m3, and only 50m3 was lost at the canal end. 950m3 of water can be directly used for farmland irrigation.

When constructing geomembrane, we really need to pay attention to these details to avoid leakage problems.

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.

Before the composite geomembrane paving, prepare the construction organization and formulate, explain the paving method and technical measures, and apply it after the supervisor's permission.

As we all know, the main equipment for producing geomembrane in my country is divided into laminating machine and blown film machine. Of course, the equipment is getting more and more advanced, and the produced geomembrane has been greatly improved in terms of vision and physical chemistry. So, how are the blue and green impermeable geomembrane processed? In theory, in actual design, users usually design with black and green on the other side or blue on the other side. In addition, when the two sides are colored, they are used for special projects. It is called black green and black blue. If you simply produce reverse osmosis membranes with the same color on both sides, you can make a laminating machine. When producing black-green or black-blue impermeable membranes, blow molding equipment is required for processing. Special masterbatch materials and ultraviolet strong carbon black are added in the production process, which has excellent durability.
