first, I will not say that when paving geomembrane the ground should be compaction, even if the ground is very soft, under the hydraulic?pressure, there is no gap between the membrane and land, what's more, how much is the geomembrane national standard tensile strength? How much is the bursting strength? how much is the Elongation? If a small loach can drill the it broken, then we can know that how poor the geomembrane quality is, of course, if you are specializing in geomembrane cultivation, black 0.35 national standard geomembrane is generally recommended, the quality is out of question in three to five years.
it is ok for the thickness about 0.35mm
