VERY large leak under concrete stream -- can't feel liner -- only dirt
Hi there.
So, I did not build this pond. I have a 25 year old, 20,000 gallon concrete pond with a liner -- well, a liner under the large 15,000 part of the pond.
The part with the VERY large leak is a stream that connects an upper pond with the large lower pond. I was cleaning it, and I noticed that the water was going into this leak instead of the bottom pond! Once the algae was removed, I found a 20 inch long by 1.5 inch wide crack. I can put my hand in it! My BIG concern is that I cannot feel a liner -- only some dirt -- but most of what I feel is just empty space. If I put water in it, it just disappears.
I REALLY do not want to redo the entire pond. Strangely, this crack is by far the largest crack the pond has. The upper ponds are "formal" ponds with tiles, wall fountains, and etc. with no cracks, and the lower, largest pond has concrete with some cracks, but it is clear there is a stable liner under it.
I have researched the web and our forum here for some time, and nothing talks about what to do when you cannot feel where the space ends under the leak.
What can I do to repair it?
Thank you!
Lori
