Analyzing Residential Retaining Wall Designs

happen so these guys like to use hybrid systems I was here when the company was installing this wall I actually called up my engineering company because I could not believe what I was seeing and they were using this hybrid system where they take a wall like this and you can see that the sidewalk was never replaced in fact like it there's there's where the sidewalk was replaced here's the old sidewalk so the sidewalk wasn't replaced and I know it wasn't because I was here when they were building it and literally all they were doing was putting this porous aggregate behind it and I've seen other youtubers do this it doesn't work and theory it works in practicality it doesn't work because as we look at this wall we can actually see this wall is already failing this wall is not that old this wall is already sliding down because of just the slight surcharge from the sidewalk it's not a big one but it doesn't have to be a big one and even in these small zones because you can't get grid in here so this is a building owner paid for this wall and they're going to be repaying for it to have it built because once a wall goes into a state of failure like you see on this one they pop like a balloon these first indicators the little signs the separation the leaning the tilt those are the signs like blowing up a balloon blah blah blah and then that balloon Pop's catastrophic failure they rupture and you can actually see on this wall as you look down it the top is actually starting to cantilever over they couldn't get the grid in they didn't have permission to cross the property line so as we look at this they were limited to that fence line it's gonna be a ditch hard to see you guys but this is actually leaning in you can see where the sidewalk has shifted and adjusted right here and that's as the wall moves out the sidewalk and everything follows suit well let's go up around the corner and see if we can spot how this looks as we transition around here I don't know it might not be as bad as it looks from the bottom and a lot of those weeds help cover it up you can see it look down you can see it's going that way because they built this 12 to 14 foot tall wall but we're limited by this fence this fence has never been removed you can look at the fence you can see the rust you can see where this fence was never touched that fence would have had to been taken out to build this wall the right way wall comes down the fence comes out they excavate all the way back into here…
