To ensure a pond liner stays in place in a natural swimming pond, the key is to properly prepare the area before installation. Make sure the ground is smooth and free from sharp objects like rocks or roots that could puncture the liner. Using a protective underlayment made of geotextile fabric helps create a barrier between the liner and the soil, preventing damage and helping it stay in place.
Once the liner is laid down, you can use rocks, gravel, or soil around the edges to anchor it securely. This helps keep the liner from shifting over time. It’s important to make sure the liner is stretched out evenly without any wrinkles or folds that could cause it to move or tear. If you're adding any features like waterfalls or plant shelves, make sure they’re designed to support the liner and not put undue pressure on it.
