With the development of large ships and the rapid economic development, some low-grade inland waterways can no longer meet the needs of cheap and large ships along the route.

The composite geomembrane has corresponding deformation variables, and the stress caused by the concave and convex defects of the underlayer can be quickly transmitted and dispersed, and the strain capacity is strong.

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.

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.

The composite geomembrane is widely used in contemporary anti-seepage geomembrane engineering projects.
