    Thanks for reply, your work is top notch.... another question. Set stones, lay fbric behind and on top, then set next row? Also backfilling and compacting as you go? I want to attempt one of these in near future if oppurtunity presents itself. Not a fan of block walls. Obviously would only attempt several small ones before I ever considered anything with some height to it. Again thx for your time and the great pics

    Pretty much. I set my rocks a certain way so I don't get stuck with trying to find a specific rock that will fit. There are certain shapes I stay away from because they are a pain to fill as I go up. I also stack 2-3 rocks on top of eachother before I backfill depending on size of the rocks. It makes laying fabric out nicer, I don't use as much and there are less fabric joints/breaks. I don't want to give away all my secrets because it's taken me years to figure them out but those are some good pointers... esp the one about rock shapes. I used to spend 20 minutes trying to find a rock to fit. Now its a minute or less on average.


    Depends on the engineered plan. Some walls have geo grid in them if there will be a load bearing structure sitting on or near it and putting pressure on the face of the wall.

    Some more pictures from that job

    Great looking work! Any idea what that 235 is burning an hour in fuel?

    With walls it's really dependent on what I'm doing. Setting base with 7' rocks and in power mode I'm at about 4.7 gallons an hour but I average 3.5-3.8 usually. 84.5 gallon tank and I fill it every 2 12 hour days but its not completely empty, rarely idling.

    Setting top row with smaller rocks I need to be delicate and I drop RPMs down to 1650 and it sips fuel then.

    Are you using Ridgid LED lightbars or the cheap-o ebay ones? Also do you do that much work at night that you need the LED lights?

    They are totron brand, I have 7 of their bars and none of them have let me down yet. In the fall we work late and the sun sets pretty early. The lights that come on the machines standard don't cut it for building walls at night or in low light.

    Company paid less (about half) to equip all of our excavators with LED bars than it would have cost to install the Doosan's factory light package on just the DX235. That included the 30" bar on top and 2 6" cubes to replace the halogens on the boom on all 3 machines. If I get a wild hair I might replace the cubes on the front of the machines too. For now 18,000 lumens is enough light. Also I compared my Totron bar to a Rigid bar my buddy paid 5x more for and from my inspection the optics are a little different but there is still a ton of light from these "cheapies". Not worth it for me.

    Thanks! Some things will just come to you. Another thing... don't just think about the boulder you are setting but think about 5-7 boulders ahead depending on the selection you have. Some people just have an eye for it, or so I'm told.
