Step 1

Determine the size of the sandbox you want to build, then dig a pit about 12" deep.

Step 2

Using a utility knife, trim the pond liner to the shape of the pit, leaving about 12" of liner around the pit perimeter.

Step 3

Make a series of small punctures in the liner for drainage.

Step 4

Fill the pit with play sand.

Step 5

Use edging blocks to anchor the liner around the perimeter of the pit. Using a caulk gun, apply landscape adhesive to each of the blocks so they adhere to one another and to the liner.
