Sawn Expansion Joints in Concrete Retaining Wall
Sawn Expansion Joints in Concrete Retaining Wall
(OP)
We have an existing concrete retaining wall ~153' long and 6-9' high. There are no expansion joints in the wall.
Has anyone ever sawn expansion joints into the wall to provide for expansion?
If so, how did that work?
Thank you in advance.

I'd consider things like:
1. Existing rebar locations/cover
2. Age of the wall.
3. Purpose of the wall. What's it retaining?
4. Other things I Can't think of right now.
Point is, whenever you tear down a fence, first determine why it was put there in the first place (to paraphrase GK Chesterton).

Then use a backer rod(s) and sealant.
How old is the concrete?

You could wire saw through the whole thing.

There will be shrinkage cracks in the wall now, running more or less vertical starting at the footing, probably spaced 10 to 15 feet apart. These cracks will not be straight. If your intention is create joints of some width, you need to consider how these relate to the existing shrinkage cracks.
