How to make a raised pond and rockery

Step 8: Protective layer on top of the pond liner

Not only did I have to protect the liner from the earth below, but also the rocks I planned to put in the pond itself.

This was the same stuff as I used under the pond liner. I completely covered the pond liner with at least 2 layers of the protection felt, to make sure I didn't puncture it if I needed to get in at any point.

Note : Quite useful to use up any large pieces you have left, in the bottom for extra protection.
