    yes, there needs to be alot of things behind that wall that the installer missed.

    geotextile fabric, i would have done atleast 2 layers on a 5ft wall to be sure.
    gravel drain field atleast 3.5' from the BACK of the wall block.
    and an extensive drain system to name a few...

    where are u located in central IL, if u dont mind me asking. i am in the bloomington normal area. if it was in my area i would like to do a drive by lol,because that has bad news written all over it. someone didnt use proper drainage. a wall that high, in our area would have to be engineered. looks like no geo grid also bad news.

    I've seen these situations before. The customer goes w/ the cheaper contractor and pays down the road because the the job was done incorrectly. I fixed a wall last yr that fell do to poor construction. The height of the wall was 5' and tapered down to 2 1/2'. the wall was built w/ no geogrid , drainage, and wasn't tamped behind the clean gravel. The last i heard the customer was still going to court w/ the original contractor for a $15,000 settlement. "Quality Doesn't Cost it Pays"

    Update, talked to my neighbor today. Come to find out they had never installed a wall before. I informed her of the little details they missed. She wants me to help them fix it. I pretty much told her it's going to have to be totally redone. first it's going to have to dry out.

    To make matters worse there basement drain backed up and a 10 foot section of a asphalt driveway they had put in sank. What a mess.

    Well if he soil is that unstable stone and drainage behind the wall may not have helped.
