Hopefully, you have decided the location, shape and size of your pond. You have dug it out and re-deposited the soil and removed any sharp objects, stones and root systems.

This next bit is a lot of fun…
7. Line the hole with a layer of soft building sand
If you enjoyed playing on the beach and building sand castles you’ll enjoy this job. The sand sticks to the sidewalls of the pond much better than I expected so it’s just a case of having fun.
Lined with sand, the first line of protection for the actual PVC liner. The sand was really fun to do and it started to look half decent. (Cam C902)
8. Line the sanded hole with underlay material.
This is the second line of protection for the actual PVC liner. I used some bits of carpet underlay for the base of the pond and some spare roof liner material for the base and walls of the pond. I held them in place with a few rocks. (Doesn’t matter what this looks like as once the pond is finished you’ll never see it)

The liner will sit on the top of this and before you create a pond lip with the pond liner you trim off all of the visible excess underlay material.
I used a flexible PVC liner, these are the most common as they will adapt to any size and shape pond.
To calculate the size of the liner you require get you calculator and tape measure out and use the following formula
Length = length of pond + (2 x maximum depth) + 1m edging
Width = width of pond + (2 x maximum depth) + 1m edging
There are a few online calculators like the one here
Only a few steps to go now.
