building a pond with gravel/sandy soil???
Hello everyone, first time poster.
We are looking to build a pond with above grade waterfall and the soil is quite gravelly and sandy. I'm not sure how I will be able to shape the side walls without everything just caving in all the time. What options to I have other than going to concrete construction? I was planning on using a pond liner.
I've seen photos of ponds using 2x12 boards to shape the interior but what happens when they rot in a few years? Also is fairly limiting to straight lines (my wife loves "curves" to everything!).
Any suggestions appreciated.
