    What is the best way to replace an existing wall. The current wall now is about 4-5 ft. high and is R.R. ties. How do i remove them and replace with block without the wall giving in?

    would need to see pics but you may be able to use a certain type of wall systems and not take the timbers out. You may only have to tear out the top 2-4 courses.

    If the ties have been there a long time, the ground shouldn't move much. I do a lot of these. Just rip the ties out and start your wall. I have a Dingo, so I pop them out and scrape some of the soil away to prevent any further collapsing in the area that I am working. Just get the wall up as quickly as possible before it rains. If the customer is rich, tell them that you will need to remove all the soil and use the geogrid method. Other wise just get the wall started and backfill with chat or AB3. Heck, even soil will work. I have built a lot of railroad tie tear outs. I tore out some ties and built a four footer 15 years ago without geogrid and it is still standing strong. Make sure the stone is the size of Pavestone Diamond Anchor, and not those Windsor sized stones, and get your base deep and level, backfill every two scores and compact.

    I guess I should have done a B-4 pic too. It is not a railroad tie tear out, but the method is the same.

    I agree, if they are poor then the wall should be built to fail.

    You really shouldn't leave wood behind a wall, it's just gonna rot out over time and undermine your drainage and backfill.

    Hey Captain, I meant that in a joking fashion. If you backfill and compact properly, these kind of walls won't fail. Some people insist on the geogrid because some designer recommended it. I have had customers pay for these designers, some who have never touched a shovel, to use geogrid on a 30 inch windsor style wall.:laugh:

    What I meant is that some customers have a budget and they would like for you to stay within the parameters. I know when a wall needs geogrid, as we all do. Compact until your arms burn:weightlifter:

    I agree too. Don't leave ties or timbers behind your install.:hammerhead: Besides, if the timbers or ties were installed correctly, the tear out should leave a good base for the new wall without too much digging.

    We have a hard time getting rid of the RR ties. Where do you dump yours?
