Hey, everyone, I am not a professional, but hired someone to install a retaining wall around my property. I believe they installed my retaining wall the wrong way, the easy way, and it is going to cause a major problem. They did not bury the first level of stones on one entire side of the yard. They actually elevated it with sand, 4-6 inches of sand on top of the road base. Can you take a look at this and let me know if this is actually going to work or if I am going to have some major problems? You can see the large stack of sand under the wall on that side. I am super worried this is going to collapse considering we have children who will be on this wall and a lot of neighbors with kids by the wall too. Any advice will be helpful. Thank you!
