Before I start with my answer, I guess I better tell you that I have enjoyed
lurking on the new group. Had to leave a while back and find a new home.
Now I will share time with both. This is back to what we once had. Thumbs
up. (bottom)

I'd like to deepen the pond this year and make it slightly bigger in
diameter. The plan was to move the shrub (flowering crab) and replace the
waterfall with a waterwheel. I was just looking at those stone blocks that
they use to raise flowerbeds and thinking I could use these to deepen the
pond.

But I can see several problems:

One, it may look like crap, giving the pond a wishing well look. I don't
have a lot of room between the walkway and the pond's edge.

Two, I don't know enough about these stones (I've seen a couple of styles)
to know if they would support the liner. Although I currently have two
layers of pavers below the water line on the top 'shelf' of the pond to
hold the liner in place before it gets folded under. Something similar
might work again. Any suggestions appreciated here.

Three, would the gaps in the stones let critters chew holes in the liner
or expose it to the elements. I guess I'd need to backfill the bottom rows
(two or three) and then put the cap stone on top of the liner.

Four, Might provide easier access for critters, raccoons etc.

Five, this would make it difficult to add a water feature (wheel or
waterfall) with the raised edge. Creative ideas appreciated.
I rebuilt my first real liner pond in 2005, removing the plant shelves and
raising the sides of the pond about 2 feet with the stackable landscape
blocks. I then covered the blocks with a geotextile fabric to protect the
liner. You can see the old pond with the block being finished before the
trade over, and the new finished pond on
http://www.geocities.com/richtoybox/pondpage6.html. Sorry I don't have any
distant shots on the site to show other views. The pond is now about 42
inches deep. The block is holding up fine. I did use the 6 inch thick
block. They weigh in at about 75 pounds per block. The thinner 4 inch
thick block probably does not have the mmmph to hold back much water.
