Retaining Wall failures are nothing to laugh about. They can cost the wall builder, the engineer, and the client thousands of dollars.

  • It's not a retaining wall if it doesn't have rebar, proper footings, filled in concrete, and drainage. You can call it a retaining wall, but it won't retain forever. Each block in a real retaining wall filled with concrete weighs about 4 times what those stackable things weigh that are held together by nothing but the same poor soil quality on the hill which could be clay or lots of landscape soil. Dry, manufactured retaining walls are good for a course of landscape boarder. Don't be fooled.

  • @CLUB82LA ,

    The RETAINING WALL is the entire geogrid-reinforced soil zone behind the blocks. The blocks on the front are simply erosion control. Properly designed and constructed, these walls are permanent structures. All those gigantic highway walls you see with the concrete panels...those are reinforced walls. They are permanent.

  • I hope these aren't ones you installed...........just kidding.

  • I do believe the object of this lesson...was a how not to do something....If' you sink steel reinforced i beams into the bed rock. And secure them with an inner layer of I beams then your retaining wall will work....you have to remember...with out a proper foundation...anything can move.

  • @Retainingwallexpert2 Your forgot to mention illegal immigrants installing these walls with no experience or I do for 5 dalla type of insallaiton... Cheap labor some of these contractors hire...

  • You are correct... Failures are nothing to laugh about. The most important thing to remember is most failures are caused by 2 things. Poor installation, and hydrostatic pressure behind the wall. In the pictures, Mostly all the cases in your library of pictures, it is due to improper installation, and rarely the product. The only product issue I can see which could be product related, would be a pin system.
