Pond Boss Forums INTRO Questions & Observations Plugging a drain tile?

So when we built the pond we just missed an old clay drain tile. From the start we knew there was a leak but thought it would stop in time. Found the tile and leak.

We plugged the leak but now the tile has pressure on it when we raise the level on the pond. The tile then leaks out the joints of each tile and give us a soft spot on the dam equal to the water level.

We have the tile located and will be marking the whole thing. Digging down and plugging off the tile.

Is there any advice you guys can give in sealing off this tile? We would love to raise the full pool another 24"s but every time we do right now the bank gets soft. Before we plugged off the tile on the lowest end the bank was never soft. I am guessing because the water was just draining away.

Thanks for any advice or thoughts.

Cheers Don.
