How to Apply a Pond Liner


Manmade ponds are a lovely addition to any garden. When filled with water plants and fish, they create a relaxing escape right in the comfort of your backyard. When creating and customize a pond, it is vital to correctly apply the pond liner to prevent leaks, tares, water loss and contaminated drainage.

Step 1

Place 2 inches of sand over the entire bottom surface of the pond hole. This will prevent rocks and roots from puncturing the liner. Lightly sprinkle the sand with water to tamp the sand in place.

Step 2

Cover the sand with a geotextile underlayment to further protect the pond liner and provide a cushion from rocks.

Step 3

Open and drape the pond liner accross the pond. Get help from friends and neighbors. Verify that it completely overlaps the pond and that there is an equal amount left on all sides.

Step 4

Secure the edges of the liner with rocks and bricks to prevent it from blowing away while the pond is filling.

Step 5

Fill the pond with water. Get wrinkles and folds out of the liner as it is filling. Reposition the rocks and bricks each time the liner is pulled tight. Once the pond is completely filled, trim away the excess liner with an X-Acto knife. The edges of the pond can either be buried in a trench and covered with dirt, or simply covered with decorative rocks.
