My father is bringing me spare auger style pier posts to build a dock on my 8 acre pond. I plan on using a pipe wrench and screwing the post down into the pond. I’m only going to go as deep as I need for stability. Is there any fear of creating a leak in my pond by doing this. I couldn’t imagine it would hurt especially because I don’t plan on taking post out. I just figured I should post this before I go and cause problems. Thanks.
