Introduction and Understanding Engineered Walls

All right, guys. We're going to be building an engineered retaining wall today, but we're going to be talking about the difference between an engineered retaining wall that holds up a load, which is this one, and then on this exact same site, we're going to be building the identical retaining wall, identical height over here, that does not hold up a load. And so, we're going to actually walk you step by step through the process on how to build an engineered retaining wall. The first thing I want to talk about real quick before we get too deep into this is when do you need an engineered retaining wall or when do you need to engineer a retaining wall and that is any wall that's over 4T in height or any wall that has a load on it and a load can be considered two things a hill another retaining wall or actually a structure like a house. So if so those are three things but technically any any wall that's going to be under those circumstances you need to engineer even if the walls under 4 ft in height at 3 ft in height. Another thing that some guys are going to be looking at this video and going screaming is well my county my city my blah blah blah doesn't require it. Who gives a crap? You're building a wall that you need to last for the customer. A hill another wall. Those things don't care if the county requires you to engineer it or not because they will eventually push your wall over and make it fall down if you don't build it the right way. That's the difference that we're talking about. So whether your county requires it or not isn't the point. The point is you need to engineer. Now let me show you something. Let's go. Let's actually look at an engineered plan. [Music] All right. Now would also be a good time for me to jump in here and explain the difference between a reinforced retaining wall and an engineered retaining wall, which aren't necessarily the same thing. A reinforced retaining wall means that it has geog grid in the retaining wall, but that doesn't mean that the retaining wall was designed by an engineer. You see, there's very few people that actually know how to design retaining walls. A lot of guys will go out and actually have a civil engineer design a retaining wall for them. And I'm going to tell you straight up, that's a big no no. Now, I know I'm going to have a bunch of civil engineers jump on here and tell me I don't know what I'm talking about, but I've tried to build retaining walls after a civil engineer has designed them, and they…
