How to Install a CHEAP Boulder Retaining wall with just a skid steer and scrap field stones

What happens here

Position the largest boulders at the base of the wall. Ensure the boulders are oriented so that the largest, most stable face is exposed and the boulder leans slightly back into the bank. Avoid placing boulders with concave surfaces facing outwards, as this can lead to instability and the wall wanting to slide forward. When tight joint spacing isn't possible, plant creeping vines in the gaps to provide long-term soil retention and structural integrity.

Goal: Properly position boulders for stability and integrate plants for long-term wall integrity.

Tools and materials

  • Skid-Steer Loader with forks ASV — Adjusting boulder positions
  • Black dirt — Filling gaps between boulders
  • Creeping vines — Planting in gaps for soil retention

shimmer who uses that word all right so a couple things I want to talk to you about Boulder positioning and I'm kind of picky and I'm not kind of picky I'm very picky but here are some basic guidelines for you guys when you're doing it yourself you see this Boulder right here you see that concave mark right there I don't like that but sometimes a boulder isn't gonna give you many options there's good boulders and there's bad boulders this is a bad Boulder it's the biggest one I got I'm kind of stuck using it so we always use our biggest boulders at the bottom and then we shrink the size up now I don't have a lot of choices here guys like I'm not trying to make excuses but sometimes you got to do the best you can with what you have so with this bulk Boulder at this post spot gave me the closest I could get up to it but the next boulder one of the things that we want to talk about is you see this Ridge going backwards if I flip this Boulder around I'd have a Ridge going forward instead of backward that's a big no-no because then your boulders are going to want to slide off we want them to lean into the bank let's go over here and take a look you see how we've got this massive setback on these stones well we do that intentionally we want the stones to work their way into the bank and not look like they're falling out because the bank is pushing them away also you got want to get your joint spacing as tight as possible but if you can't get it tight there's a couple things you can do you can literally plant the joint spaces packed black dirt in between these spots that you can't get a stone and then plant a creeping vine and those creeping vines that you plant net the wall together the roots go in there they keep any water from eroding the soil out between the boulders they just hold everything together planting a boulder wall is actually going to be stronger long term than fabric because those plants will continue to grow 1020 years down the road and that fabric will eventually break apart fall apart and be useless in that same amount of time so planting a boulder wall overall will give you a better long-term result alright next
