Installing a canal liner in a sloped area requires careful planning to ensure the liner stays in place and functions effectively. The slope can cause the liner to shift or become misaligned, so extra measures are needed to secure it. Before installation, the slope must be stabilized by grading and compacting the surface to create a smooth, even base.
For flexible liners like geomembranes, proper anchoring at the top and bottom of the slope is critical to prevent the material from slipping. In some cases, additional support structures, such as anchoring strips or retaining walls, may be used to hold the liner securely in place. The liner must also be installed in a way that accommodates the natural flow of water, ensuring that it doesn’t stretch or tear under pressure. For concrete liners, extra reinforcement may be needed to handle the added stress from the slope. Special attention should also be paid to ensuring the liner's edges are sealed properly to prevent water from seeping underneath.
