Pond Boss Forums POND CONSTRUCTION Renovating a Pond or Lake? hole in back of pond

hey pond boss
i posted a picture of a hole in back of the dam...it was suggested that i put some type of concrete in it...question...i need this product to be thin enough to travel into tunnels going out around the bottom of the hole ...can i just mix it so that it will be thin enought to flow freely and still have it harden?

did you guys forget me? help

mornin miss nancy, sorry i didnt see the picture or what was recommended, i'll look for that, but based on yer post above, a neat cement slurry came to mind. you could mix that too a consistency varying from almost water to toothpaste depending on what you need to seal. you could also pump it in w/ a typical trash pump provided the tunnels and such flow downhill, otherwise you'll have a big mess on yer hands.

lets see if anyone has ideas.......

thanks...i think i have my own thread...whatever that means..in renovating ponds...i have cleaned debris out of pond and off the dam...i don't know that filling this strange hole will stop the leak but it is worth a try....i have a quite a few posts from my fall pond panic and you can see the dam hole...

There is a "hydraulic water plug" cement that will set-up under water. We used it when we were sealing a concrete bridge that a shipyard turned into a pier. They towed it to San Diego from the state of Washington and it was cracked on the trip down. We had a diver in the water sealing the cracks, and we were on the inside injecting epoxy into the cracks to seal/glue them together.

The cement that we used was made by Sika Company. No aggrigate in the cement.
