The main performance advantage of widely used geomembranes is their anti-seepage performance, especially in anti-seepage systems used in engineering, which plays a very important role. The high tear resistance of composite geomembranes also lays a certain foundation for their high anti-seepage performance. Let's learn about the tear resistance of geomembranes together.
In the construction of anti-seepage systems, when we lay composite geomembranes on the upper soil, the self weight stress of the soil will significantly increase, which may lead to small-scale settlement of the reservoir under the dual effects of gravity and water pressure, causing the composite geomembrane in the settlement zone to bear a larger load. When the load exceeds the load that the material itself can bear, tearing phenomenon will occur, This causes local leakage in the material protection area. Therefore, we can see that the thickness of the soil above has a significant impact on the tear resistance of the material due to gravity. When the water level in the reservoir drops sharply, the water level of the soil in the reservoir will also decrease, which may cause unstable factors in the anti-seepage system structure of the material and cause tearing.
The tear resistance advantage of composite geomembrane is also the key to ensuring its normal anti-seepage performance, which can withstand the high load pressure of soil and achieve good anti-seepage effect to meet the needs of engineering. I hope everyone can have a more detailed understanding of composite geomembranes after understanding them.
