Keystone retaining wall question

[Hibbing]

I'm looking for someone with knowledge of keystone retaining walls. The one in my backyard has leaned out quite a bit. What are my options? I have a few ideas I would like to bounce off an expert.

How high is the wall? What is it holding back? Google allan block and you will find all the information you need. I looks like you may need some geo-grid to hold it back.

Was it started with a good base or footing? Is the bottom course sinking? If it is that would most likly be your problem.Either way only one sulution,start over,I'm no expert but experienced in block walls and retaining walls,and your best wall is how its started befor a block or brick gets laid!

It could be a lot of things. You may need geogrid like the previous post depending on the hieght of your wall, but it also might be related to your bottom course, was one row burried? is that bottom row tipping?

Also my experience is that the fill used behind can make a big difference. Any fill that allows water in and no way out will cause major problems.

Basically it could be a lot of things.
