When using composite geomembranes, what temperature-related effects should be considered, and how do ambient temperatures influence these materials? As a composite geomembrane manufacturer based in Shandong, let our experts walk you through the details.
The creep behavior of composite geomembranes is strongly influenced by temperature variations. Based on the creep characteristics under low-temperature conditions and freeze–thaw cycling, the creep strain decreases as the ambient temperature declines and eventually approaches a steady state.
When creep has stabilized under ambient temperature conditions, the concept of the freeze–thaw cycle influence factor DR is introduced. During the freeze–thaw cycle, the creep value increases during the heating phase. Furthermore, a method for calculating the low-temperature creep influence coefficient FcR is derived.
From an engineering cost perspective, using composite geomembranes as the impermeable liner results in a cost that is more than 50% lower than that of a gravel filter layer. This approach helps prevent river pollution and soil erosion, thereby contributing to environmental protection.
The ambient temperature should generally be above 5°C; under low-temperature conditions, construction should generally be avoided during winds of Force 4 or higher, as well as in rainy or snowy weather. At low temperatures, the composite geomembrane will tend to tighten, whereas at high temperatures, it should be allowed to relax.
