What must be done to avoid deterioration of a membrane liner from weather exposure?

To avoid deterioration of a membrane liner from weather exposure, it is essential to fully bury the liner. This practice protects the liner from direct exposure to sunlight, extreme temperatures, and other environmental conditions that can cause damage over time. Ultraviolet (UV) rays, for instance, can break down the materials that make up the liner if they are left exposed, leading to a reduction in integrity and effectiveness.

Burying the liner not only shields it from these harmful elements but also helps maintain proper installation and function within the septic system. It ensures that the liner remains in place and performs its intended role in separating the septic components from the surrounding environment.

Other practices, such as leaving the liner uncovered or using non-protective materials, would expose the liner to potential damage and are not advisable. Elevating it above ground could also lead to exposure to the elements, making it less effective. Therefore, fully burying the liner is the recommended approach to prolong its lifespan and maintain the integrity of the septic system.
