Installation

• 1). Mark the outline of the liner on the ground. Place the liner where you want it situated and use chalk or string to trace an outline that is slightly larger than the upper edge. Do not turn the turn the liner upside down and trace unless it is symmetrical or you will get a mirror image of its actual shape.
  
  
• 2). Dig a hole that is as deep as the liner is tall. Place the liner in the hole, mark an exact outline of the bottom using chalk or string, and dig a smaller hole 1 inch deeper than the main hole.
  
  
• 3). Place sand, old carpet, or old fabric in the bottom of the hole. Sand is malleable and will help you get the height of the liner just right.
  
  
• 4). Place the liner in the hole and check that it is level using a carpenter's level. Adjust as necessary.
  
  
• 5). Fill the liner with water to help it settle properly. While it is filling with water, pack sand into any gaps between the liner's walls and the surrounding soil. Get as tight a fit as possible.
