Question
We have a small pre-formed pond that worked fine, but one end has sunk into the ground around 6".  I don't want to dig it up and start over -- I think the easiest solution is to build a small cement curb around the low end to let the water level come up a few inches..

is there a better, faster, easier and cheaper solution?  

thank you very much!

Answer
Hi Jeffrey,
If it is a preformed plastic pond you will have a job trying to make a waterproof seal with your cement, I would suggest the best way is to empty it and lift it out and start again with a level base ,it will be best in the long run because it will have been done right any other way and your always going to have problems and wish you had done it right in the first place.
