Canal liners handle temperature fluctuations differently depending on the material they're made of. Flexible geomembrane liners, such as those made from RPE, are designed to expand and contract with temperature changes, allowing them to withstand seasonal variations without cracking or breaking.
However, extreme temperature fluctuations can still stress these materials, potentially leading to issues like tearing or shrinkage if the liner isn't properly installed or maintained. Concrete liners, while more rigid, are more susceptible to cracking due to thermal expansion and contraction, which can compromise their integrity. To mitigate temperature-related damage, expansion joints or reinforcement may be used in concrete installations.
