WHY Retaining Walls FALL down - How Most people Build them Wrong

What happens here

The presenter examines several real-world retaining walls. He points out signs of failure such as bulging, shifting, and separation of blocks. He emphasizes that these issues are often due to poor construction techniques, particularly insufficient compaction in critical areas like corners, or the complete absence of geogrid. In one instance, a wall that appears to have some geogrid actually shows it has settled and is no longer providing adequate reinforcement, highlighting the importance of proper installation and design.

Goal: Identify common failures in real retaining walls and relate them to geogrid and compaction issues.

And this wall is failing, too. So, as you look down it, you can see the base is shifted. I mean, and look at these tears. This is where a lot of guys go wrong is right on the corner of a terrace because it's very difficult to get compaction. So, you've got to take extra time. Right here, this is where And see it there. Yeah. And you can see it there. You see how they've separated? See that? Because right in this area right here, Frankie, behind this wall, they can't get the they can't get the compactor to do as good of a job or they're just Well, they you can, but it's a lot more difficult. And so, you'll see it's there and over there. You see the same thing on the other other side, right? There's a number of problems with this wall. And then on the other end of it, it's already leaning over. This whole corner is in a state of failure. So, it's all coming forward. They use good block. They used uh this looks like keystone. Yeah, that's a keystone block. It's got fiberglass pins for reinforcement. That's a good block, but bad building techniques. Yeah, you can see where the whole wall is just shifting and and in a state of failure. I don't even see any of that matting in here. There's no geog grid in this wall at all. I mean, you're not supposed to be able to see it, but when you can see it on one row, typically that becomes the installation technique of the contractor to do it multiple times. They they usually don't make a mistake because that just means they're sloppy. So, they they either show the grid or they don't show the grid. And so they've got in this entire wall one row of grid. So this wall is going to fall into this house and it's not going to take very long. Oh my gosh. Okay. So we do have another row of grid. Look at it. It goes
