Pond Boss Forums POND CONSTRUCTION Renovating a Pond or Lake? Leaking, rotted outlet pipe

Welcome to the forum!

Unfortunately, you know the best way to fix the problem, all you lack is funds. If you end up going that route, don't forget to add anti-seep collars.

I'd look into the sleeve for the next option. The only suggestion that I have to seal the outside of the pipe is to dig down and pour cement or bentonite around the outside of the pipe as close to the pond side of the pipe as you feel comfortable digging.

Going the "pressure grout the leaky pipe full" and let the emergency overflow handle the now normal overflow isn't recommended at all. If it's the standard grass covered soil overflow, there's a very good chance that the increased water flow will slowly wear it away and cause the whole dam to fail.
