The quality of composite geomembrane has always been one of the concerns of the geotechnical professionals. Especially for some materials which need to be put into some large-scale construction projects. The quality of materials must be well controlle. In order to meet the needs of use and a certain service life.
So in the process of purchasing, what should the purchaser do to judge the quality of composite geomembrane? In fact, this is not a difficult thing. We can judge the quality of composite geomembrane by using some basic judgment skills we have mastered.
First, we can observe the appearance and structure of composite geomembrane. Generally, the appearance and structure of materials with high quality are compact. Its structure will be stable. Comparatively compressive. However, some composite membranes which are not up to the standard have poor materials. And the structure is unstable. It is especially easy to collide and fall off during transportation.
Moreover, we can also try some basic functions of the materials to see whether these functions meet the standard in normal use and whether there will be leakage; because the quality of geomembrane materials is the final factor that directly determines the quality of construction, which must be well grasped.
