A crane drops rocks through a bag onto a pond liner, releasing them gently from the bottom to avoid puncturing the liner before the pump starts. One hole and the whole project floods.
Chapters
And when they are putting all this gravel in, a lot of times they'll have a crane and they'll have this big bag of rocks and they'll have an opening at the bottom. So when they're coming up, it's almost like, uh, the reverse of a— I don't know the right word for it— siphon of some kind. And they just drop the rocks in and it protects the liner from all those rocks dropping. So that makes sense because it would be really bad to build this pretty pond and then have a hole before you get to hit the pump and turn it on. Oh yeah, I would imagine if I'm ever in that position, that will be a bad day. Be the first day I cry on the job for sure.
