To add rocks or gravel without damaging the pond liner, start by ensuring the liner is clean and free of debris. Use smooth, rounded stones instead of sharp-edged rocks, to avoid puncturing or tearing the liner. Begin at the pond edges, securing the liner in place with the stones to create a natural border. If you're adding gravel, spread it evenly and keep the layer thin to minimize pressure on the liner. When working with larger rocks, position them thoughtfully to create stability without applying excessive weight in any one area.
When placing large rocks or large amounts of gravel, do so gently, avoiding dropping heavy materials directly onto the liner. Instead, lower it carefully or use a wheelbarrow or bucket to transport the materials closer to the edge before placing them. To place gravel along a slope into the pond itself, install a speedbump or curb to keep the gravel from slipping down to the floor of the pond. The curb can be as simple as a perforated pipe.
