2c. Determining Liner Size

To determine the size liner needed:
1) Figure the smallest square or rectangle your pond would fit in from a top view.
2) Draw two cross-sections of your pond. One representing distance A in the diagram the other representing distance B. List all measurements. Example: you would need the distance down to the first ledge, if there is more than one, then the distance across the ledge then the distance down to the next ledge and so on (see example). This would continue until all measurements were filled in on the diagram from one side to the other.
3) On each drawing add 12 inches to each side for overhang.
4) On each drawing add another 6 inches to each side for a margin of error or any additional material your design calls for.

Final Length = Length + 2 X Depth(") + 2 X 12"
Final Width = Width + 2 X Depth(") + 2 X 12"

PONDGUARD LINERS
Firestone is the #1 manufacturer of pond liners
in the USA. PONDGUARD is the best liner material available and has a 20-year membrane warranty. In addition, this is the only liner that is tested for toxicity and is "fish safe." 45 mil.

Tip! Whenever possible, plan your pond to use only one liner. Piecing liners together can cause problems with separation and leaking. When joining waterfall liners to the main pond liner, be sure to allow enough length of the waterfall piece to give good overlap.

Don't underestimate the width of liner required for a waterfall - allow enough extra width to build up dirt and support rock work along the edges to give the waterfall enough depth to contain the water and deliver it to the main pond.
