    Number one reason for using #57 stone for base..........Survey Said

    He told me the name about 3 or 4 weeks ago, but it went in one ear and out the other. He said it is a decent size company with trucks that are all over town, mostly nice newer trucks. He said that was what sold his wife.

    The wall was poorly constructed, the company routed the roof water down spouts to discharge behind the wall without daylighting them!!!! Which in-turn cause water to hold under the asphalt driveway. So now the asphalt has buckled. My buddy and his attorney had the contractor file a claim with his E&O insurance. And through the grapevine my buddy found out that this was not the first nor the only claim this contractor has filed with his E&O coverage.

    I will have to text my buddy and find out the name. I'll be speaking with him this week, but I can't ask him on the phone because he'll go off on a 15 minute spiel about the contractor, and I'm not exagerating. Whenever I get the name I'll PM you.

    Kinda funny how a contractor 6-8 hrs away in another state finds things out :cool2:

    Actually just the opposite. It's harder to level and harder to set the block on.

    I'm a-kinda-wonderin how much (if any) experience some of these thread participants have buildin walls :walking:

    i hope you're just being silly, as no, not at all

    Retaining walls are not to be taken lightly. The liability with retaining walls follows the builder for as long as he/she is in business, or until he/she dies, depending on their business entity. So it's important to disseminate correct information.

    Lordy, you need to learn to use paragraghs, sir. My attention span is very short and I bore easily. And it's been a long day running an excavator with a hammer on it for 10 hrs straight. :drinkup:

    So - my eyes more or less only read your last sentences.

    There is no one size fits all reasoning for deciding what aggragate to use for the base.

    Your drainage chimney will be 3/4" clean, herein after referred to as "#57".

    One example:
    If material staging is tight on the site, it may be easier to just use all the same aggregate (#57), delivered in one load on one truck from the quarry. There may not be room on a site to stage two seperate piles of stone, plus the block, plus the soil that was excavated.

    Also, a wall may need 100 to 200 tons of #57 for the drainage chimney. But maybe only 10 tons of aggregate is needed for the base. It may make life simpler to just convert that base aggregate to #57 instead of paying the quarry to bring out a measley 10 tons.

    first of all DVS its simple, i dont by into everything im told to sell...i dont build it unless i know its correct. It dont take a rocket scientist to know that river rock does not compact, and since it does not compact therfore it has drainage properties....now talk till you're blue in the face and you just make yourself sound like one of the guys you were talking about that dont even know much about building walls (and go ahead with what everyone else tells you is right, i guess).....answer me this, if its correct to backfill a wall with #57 for drainage (would that not (SELF)compact behind the wall then and prevent drainage as you said? WRONG!!.......and i'll tell you why. Because proper drainage behind a wall does not go all the way down to the base, and should actually be even above first course, then follow grade or (FLOW) away from the highest point to the lowest, if not daylighted.....and what good would that do to extend base of drainable properties wider than the block?...so daylighting would flow right back under the base..hahahahahaaa......and dont even go there with concrete as a base. Even engineers should know that limestone or concrete has no drainage properties and is asking for problems to the opposite extent. #57 crusher is perfect for its compaction as well as drainage indeed for any ground water to flow slowly...............but for all folks that do as they are told instead of using common sence. I imagine there could possibly be some applications where this would work, or i should say, make it work (i mean i could if i want....BUT I DONT PERIOD!!.........but i assure you there is a correct way to do everything

    It will need rebuilt. Actually, this isn't recent, I believe it's been a couple years. I think my buddy is still furious about it all and hasn't wanted to fool with it. But he did mention that he has to start thinking about re-doing it. I don't see how he would have time to do it himself. But I can tell you - whoever he talks to about rebuilding it is going to have their competency interrogated to death and will be cross examined in every direction thinkable.

    My buddy used to be a general contractor. At the time the wall was built he was very busy and his wife handled everything. This was the first and only time that he let her handle something like this. She wanted to use this contractor because some of "the neighbors used him".

    As the project got underway my buddy kept observing flawed practices and he would question the contractor. It got worse and worse, to the point where it became obvious that this big, well known contractor didn't know what he was doing.
