1
Rake the bottom of the dug-up ground to remove rocks and other debris that could puncture the liner.
-
2
Apply the underlay. The purpose of the underlay is to ensure that the liner is resting on something that will protect it from anything that could compromise its integrity, such as stones, sharp objects and penetrating roots from nearby trees.

3
Reinforce the pond's edge. Use bricks and mortar to define and strengthen the perimeter of the pond so that the edge of the liner does not collapse into the water.
-
4
Lay the flexible liner. Strive to lay the liner centrally so that the edge overlap is equal on all sides.
-
5
Add water. Use a water hose to fill the pond a little at a time. The creases will flatten out as the water level rises. Hold down the edges of the liner with bricks to prevent it from collapsing into the water.
-
6
Trim the excess liner. Once the pond is full, trim off the excess liner with a pair of scissors. Leave about 2 feet of overlap.
-
7
Lay bricks or slate rocks affixed with mortar over the liner's overlap to finish the edging of the pond.

Tips & Warnings
Stone slabs and other natural rock formations can be used to camouflage the edge of the pond liner.
Cement or mortar is toxic to fish. Be careful not to drop any into the water.
