Answer 1

I would try, I have done this twice, using "Pour Stone" and add concrete glue to all cracks and concrete joints. Usually leaks occur where two unlike materials meet, such as stone and concrete or concrete meets a different pour of concrete, known as a cold joint.

Using two trowels, push mix into all voids and cracks. I have also applied concrete glue initially and then apply the pour stone.

Answer 2

Artisan took the words out of my head & my mouth. I too have a coi pond with a rock waterfall and had experienced the same problem...but the quantum solved it. Good luck & the fish all lived!

Answer 3

Try Using Qauntalgum from QVC its excellent! Its non toxic, can be applied under water and lasts for years, seals anything

Answer 4

There are no obvious places where it is leaking from. I used a sealer on all suspect places. After it dried, I used cement on all the places where there was shrinkage, or any other sign of possible leaks, then cemented the entire back of the fall. I am loosing about 10 gal every 24hrs. I am wondering if there may be cracks in the stone that are not obvious to the naked eye. So, would it be feasable to silicone the entire back? I am thinking, spreading something that can "find and fill" would be the best option.
