5 main causes Retaining walls fail.

What happens here

Compaction is described as king and a critical element for the long-term success of a retaining wall. The host explains that soil will naturally move over time if not properly compacted. When compacted correctly, the soil behind the retaining wall will remain stable, even if the face of the wall is removed. This prevents subsidence and keeps the wall structure intact. He emphasizes the importance of using a plate compactor to achieve dense, stable layers of backfill, preventing future settling or movement.

Goal: Stabilize the soil behind the retaining wall to prevent future settlement and ensure long-term wall integrity.

Tools and materials

  • Plate Compactor Bomag — Compacting soil and aggregate layers
  • Shovel — Spreading soil in even layers for compaction
  • Backfill Soil — Filling the space behind the retaining wall

walls our retaining wall when it's built properly you can take the face of the retaining wall off from it and that soil should remain in place let me talk let me give you a little bit more description about it so in this case on this retaining wall over here I could remove all of these blocks now this wall is like a decade old or 15 years old I don't even know how old it is I could remove all of these blocks and the soil behind this retaining wall should not move because I've properly compacted it I've put in the right amount of engineering the geog grid I've got the drainage aggregate the only thing that this block is actually holding back is erosion at this point it's almost like the face of this block is lipstick I'm slapping on a pig I'm just putting this in front of all of the dice the the engineering and work that I've done on the soil behind the retaining wall that allows me to hold up a structure now this is an example of a surcharge we talked about a lat it's ear it's just a deck but it's still putting additional load onto my retaining wall so this retaining wall was engineered to handle that weight and if I remove the block from this the soil is still engineered to handle that weight so a good retaining wall uses not just good uh building practices with your retaining wall block but a good retaining wall the right retaining wall or the way a retaining wall should be done also works on the soil behind it so as you watch this video you notice Tim spending a lot of time making sure that the soil behind it is is compacted right is set in place right and there's certain tricks that we are doing in this retaining wall that I don't recommend for you guys to do and what you see us doing when I say I don't recommend you guys doing it because this is kind of some Advanced Techniques we know what we're doing we've been building walls for 25 plus years big walls massive retaining walls we'll go multiple tiers up we'll flip that grid over the face then we'll back fill and when we get to the level where the grid is we'll roll that grid back down then we'll continue up putting our gr our drainage aggregate in and our back fing material but this allows us to not switch gears so often not to put one or two courses in then put dirt in one or two courses then dirt we actually have it design down to the point where we can put multiple courses in and then back fill but we also know what we're doing so just be cautious if you're going to attempt to do what you see us…
