Some canal liners are resistant to UV degradation, but it depends on the material used. Geomembrane liners like RPE are often treated with UV inhibitors to enhance their resistance to the sun's harmful rays. These treatments help prevent the liner from becoming brittle, discolored, or weakened over time due to prolonged exposure to sunlight.
Concrete and compacted clay liners are naturally less affected by UV degradation since they are not as prone to sun damage. However, UV resistance is an important consideration for flexible liners, as prolonged exposure can lead to reduced lifespan and performance. Proper installation and maintenance, such as using protective covers or applying UV-resistant coatings, can further extend the durability of a canal liner exposed to sunlight.
