Is 2mm geomembrane suitable for fish farming? The use of 2mm geomembranes for fish farming may not be a common practice, as such membranes are usually used to prevent seepage and protect soil or bottom structures, rather than as part of the fish ecosystem in the water body. Fish farming requires some specific environmental and […]

Geomembrane elongation at break test The elongation at break test of geomembranes is a test method used to evaluate the tensile properties of geomembrane materials. This test is often used to determine how much stretch a geomembrane can withstand when a force is applied, and how far it can stretch during the stretching process. The
