Pond Boss Forums GENERAL QUESTIONS Help Leaking overflow tower! Can I fix?

Now that I've been inside of it and attempted a fix, I can be more specific about what's going on.



The tower is made up of two preformed concrete boxes with additional concrete walls poured all around it to seal them together.



It's leaking from almost the entire perimeter of where the two preformed boxes are stacked together. It's also leaking where the bottom outlet pipe exits the drain tower. In other words, it's a mess.





I pressure washed the inside, as best as I could, and I spent a whole day trying to patch the leaks with hydraulic cement. I'd plug it in one place and more would just come out in another. I eventually got it to where it's just trickling a little.

Even though I have mostly stopped the leak. I know I've wasted my time. There's no way this fix will last very long. The hydraulic cement is mostly plastered over top, it's not addressing the actual leak. If it lasts the summer, It guarantee it wont last a freeze.
