How to keep light weight large stones not to fall.

[Meyer Jordan]

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?

Use plain old Rip-Rap for all the submerged rock. It is dirt cheap. Plus you will be creating all sizes of micro and mini-habitats.

What is Rip-Rap? Is that the name I would ask for?

It is commonly used to stabilize roadways, shorelines, jetties, etc. Any of your local landscape companies should know the closest source,

Thank you. It's name here is slag. Knowing the ponds shape the small stone base of slag would have to be too thick, too wide. Real stones the approximate size of the pumice could possibly be used. Lot's of thinking to do. I could be wrong.

Are your pond walls 90 degree vertical or sloped?. If vertical you will need a large base.

The trouble side has a little slope. I'm concerned that a truly proper base layer of slag would become host to muck. Am I over reacting?

I appreciate your helping me better understand the in's and out's.

If I'm understanding correctly you want the pumice stones to overhang the pond edge slightly. A wall of "hand boulders" would be perfect. Larger stones on the bottom, smaller ones near the top and you have a wall to support your lightweight rocks.

You are quicker than me, Lisak!. That would be the method.

I'll post a few photos tomorrow to help clarify what I want to do.

The first image illustrates the problem of supporting the upper stones. Seeing the pond during last years cleaning clearly shows that a lack of support to the stones on the slope is the problem The second image shows the back of the pond where there is no problem.

Here is a recent photo showing how the stones have fallen.
