A case study of lotus pond aquaculture project

　　The lotus root pond anti-seepage membrane - is a black plastic film geomembrane laid for anti-seepage in lotus root ponds. Currently, the thickness of the anti-seepage geomembrane used in lotus root ponds is basically 40 threads, which is a 0.4mm thick anti-seepage geomembrane.

　　The choice of a thin or thick anti-seepage film for lotus root ponds cannot be generalized, but needs to be considered comprehensively. Generally speaking, a thick anti-seepage film for lotus root ponds is better than a thin one. However, there are several situations that need to be noted:

　　1、 The same thickness standards vary in quality, for example, the 0.3mm thick urban construction standard anti-seepage film has better quality than the 0.4mm thick new national standard anti-seepage film, and the price is also expensive.

　　2、 The quality varies depending on the materials used. The quality of a brand new material with a thickness of 0.3 millimeters is much better than that of a recycled material with a thickness of 0.5 millimeters. The above situation shows that the thick ones are not necessarily better than the thin ones, and the suitable ones are the best. The friends who feed lotus roots here recommend at least 0.3mm for new materials, and at least 0.4mm for new national standards. Note that you must choose to add UV (anti ultraviolet, anti-aging) anti-seepage membrane products from regular manufacturers.

　　Production specifications of lotus root pond anti-seepage film: The thickness of lotus root pond anti-seepage film is 0.2mm-3.0mm, and the width of lotus root pond anti-seepage film is 0.3mm. The geotextile film is 1-14 meters wide, and the length is generally 50-100 meters. It can also be made according to the size and length of the pool, and can be directly laid back.
