Yes, pond liners can be effectively used in ponds with waterfalls or streams. When installing a pond liner in such settings, it’s important to ensure that the liner is properly sealed and secured to prevent leaks. For waterfalls, the liner should extend up to the top of the waterfall to contain the water flow and create a seamless transition from the pond to the waterfall feature.
A flexible material like RPE or EPDM can be shaped around rocks and contours, which is ideal for creating natural-looking streams and waterfalls. It’s also a good idea to use a robust underlayment to protect it from sharp rocks and debris that may be present in these areas. Pay attention to water management by ensuring that the waterfall and stream do not create excessive erosion or movement that could displace the liner. Ensure your seams and connections are strong, secure, and leakproof.
