What if....
I want to ask a question about something dealing with how to fix a pond of this same design that leaks?
Lets say that you all own a pond just like the one being built in this topic.
Lets also say that you also have found that the cement leaks and needs to be sealed before you can fill with water and add fish.
Is there a type of coating that you could roll on or spray on that would make the pond waterproof?
Given the shape of this pond, with the many pipes and long walls, is a pond rubber liner workable?
What would you do?
