What happens here

At the third job site, the landscaper examines a failing timber retaining wall located underneath a four-season porch. Previous landscapers were deterred by the complex repair. The current plan is to remove the existing wall and regrade the area. He explains that a new retaining wall is necessary here because the soil will exert pressure on the porch's footings. He also specifies using 3/4 inch angular limestone as backfill, rather than Class 5 gravel, because it prevents voids and settlement issues due to its angularity and lack of fine particles, ensuring long-term stability.

Goal: Replace a failing retaining wall with a stable, engineered solution to protect a four-season porch foundation.

Tools and materials

  • Heavy Machinery — Excavation and grading for wall reconstruction
  • Timber Retaining Wall — Part of the landscape to be removed
  • 3/4 inch Angular Limestone — Backfill material for the new retaining wall, preventing settlement and allowing drainage

What they say

Yeah. All right, we're at the next job site meeting with the customer. It's got an interesting situation. So, we got a retaining wall that is underneath a four season porch. And it's in the state of failure. I guess a couple of landscapers have already been scared off from this thing, but I think what they're trying to do there's a retaining wall underneath there. I think what they're trying to do is replace it underneath there. Mhm. We did another job with Dave We did another job with you, David, for one of your clients where we removed the retaining wall. He's got the same situation and we're going to grade this down cuz we don't need the retaining wall here. Somebody built the retaining wall, but didn't need one, but somebody built okay with taking part of this retaining the retaining wall under here. Where do you need it? And we do need one under there. Cuz that soil will push on This is a four season porch, so it's on footings. And you can see right there that we can't let that push on it. That's what we got to eliminate. So, we're going to remove that retaining wall and just push it back to gain space. The benefit is it's going to allow this foundation to breathe better. A lot of guys come into these situations and they see the existing conditions and they think that's what's got to be done. I never do that. Every time I go out to a job site, guys, I always try to look at what's already there, give the customer that option of redoing that, but then give them two additional options. And that's the challenge, man, when you try to come up with two additional options, holy crap, that can be difficult, but it's surprising how often that works. I don't know. We don't use class five under our our base. Not anymore. Some customers Some Some contractors do use class five. We don't use it. We use 3/4 limestone. It's angular. It's like a granite stone, but its ability it's 3/4 in in size. It has no minus in it. It allows water to pass through it. It locks in place as soon as you put it down. We've never had a wall settlement issue using that ever where with, you know, class five because it's got fines and, you know, smaller particulate matter that can get washed out. Sure. It can also create voids and settlement. So, we don't use it. It's a more expensive process using that stone, but it also you never call me back saying my wall failed. want? You've torn enough of them down to see what happens to that class five
