How to keep light weight large stones not to fall.

[Big Lou]

View attachment 79103 Along the steepest portion of the pond I have trouble keeping light to medium weight large punish stones (avg 1.5' across x 2' high x 1' thick) upright. I've always used some type of wedging method or base stone. Because of the steep bank slopes at the bottom there are occasional failures. Hope you can help out with ideas.

Hard to comment without the picture, but are these pumice rock? If so, use a heavier stone.

Even if it is pumice you maight be able to use foam.

I just put lightweight rocks under my waterfall using a modified sissy sock. I used black screen and sewed a few pockets in making sure they lie below the water level then I am able to put rocks into the pouches. It works wonderfully! I hope this helps!

Can you post a photo of a Sissy sock?

Here you go. I just did another one for under my waterfall. It works wonderfully and is easy to make.
Post #16 shows how I did it... I hope it helps and works for you.

That rock sock thread is hilarious!

Yeah we can be an odd bunch. (By we I mean them of course... )

I think a pond plant bag filled with pea gravel could possibly serve as a base for my big pumice stones. Hopefully would confirm to both the pond side bottom slope and to the big pumice stones bottoms shape. What do you think?

 

[tbendl]

I'm not familiar with those. I wanted something very low profile that would just hang below the water surface and it had to have small pockets for the size of rocks I was planning on using. I would say have at it and see what happens!!

After looking again at the plant bags they would not work.

Lou, is there a specific reason that you do not want to rock the entire pond wall? That would be the easiest and most stable solution.

I would like to but I do not have enough of the pumice stones. Guess I could buy the real thing to make up the shortage. Why didn't I think of that?
