| [quote=garywalker;101776]What do you recommend as underlayment for a new pond with a liner?
Gary
Definatly the felt fabric it has been used for years in road construction . It is great to lay down so that you have less problem laying down your liner and avoid extra creases as each fold holds some dead water trapped under it . If you are going to lay stone one should pour a cemment colar first this will help to hold the liner and finishing stone in place as well as allowing to make steeper sides without them collapsing . The felt can be wrapped neatly over the corner of cemment in fact a double layer at corners of cemment
If you can not afford felt fabrick under the liner do not even start .
