How to separate decorative concrete blocks glued with polyurethane adhesive.

I have a 40' long concrete block planter at my home that we built seven years ago. Frost has spread two of four rows of blocks at one place where the planter
curves. How can I separate the coping or top row of block from the second row?
They are locked together with the recommended bead of polyurethane adhesive.
I have considered "sawing" it out with a piece of wire but this may not work.

Some wide angled pics might help.

Since you probably do not have a footing, gluing rigid block block together with a strong adhesive to create a rigid wall since "Mother Nature" will always win and the wall will crack and heave depending on the geometry of the curves.

Segmental interlocking retaining wall block with no mortar or adhesive could allow you to build curved walls that do not retain the moisture and still move with the weather and seasons. Strong adhesives do not do well when facing "Mother Nature" since they allow no movement.

Without a photo, it is difficult to see what you are dealing with.
