    Just need some insight on an Allan Block corner. We are doing a wall with 6 degree AB block, which we've used in the past. The problem is this wall needs corners that are more than 90 degrees. The last wall we did with these stones only had 90's and I assume that they don't make another block for corners that are more than 90. I know that they changed to this new corner block but just wanted to confirm the cutting to achieve the new corner( more than 90). Any help would be apprecitated.

    Yes you wil have to cut the block to go more than 90 degrees. You should only have to cut a couple per course so that should be no problem. I do like the look of the block, but the minimim curve diameter is 144", so if you have any decent sized curves you will get in to a lot of cutting. Also how tall will the wall be. Make sure your using geogrid. We just bought our first load of material from Allan Block last week, they seem to have a lot of different types of blocks and pavers.

    Yes the previous post is correct also you can control your set back of how much you cut. Ive been installing them since 99 with over 150 out there. They to me are the best srw system out there. How ever they have flaws also. This corner block in reality really sucks. I wish they made it the full size of a block. If you make a corner say off of a set of steps and that run goes to a structure ( house ) you will have to cut a block. We dont like cutting blocks that why we use the jrs and the lites. We offered our services to them on designing a block or told them just hire a un educated idiot for an enginer to get it right. Any questions on allen block feel free to contact me.

    very true. AB corners suck. I can't figure out why the corner is not in the same multiples as the stretcher (18")

    I started out using AB, but am finding out that there are several better options. I still like AB for tall walls and shoreline applications, but I'm quickly becoming hooked on Techo.

    We just used AB for the first time. The only reason we used AB was because we had to match a new wall to an existing wall. The thing I didn't like about the corners was having to notch the corners to enable them to align with the rest of the face.

    AB is the worst block

    Versa-lok and Nicolock - the best :)

    Does versa -lok have a hoolow core/ What is a Nicolock? What dont you like about ab. Ive got them down pretty good now ive been using them for so long i know the flaws. Im here in alleg. co on hill sides building walls to hold back something and feel they are a strong system. We only have ep henry other wisw a new dealer took them on 2 years ago . Im not convinced they are better so i havent changed.

    AB, Anchor, Techo, Bolduc, Belgard

    Versa Lok isn't really local, but I have a guy here that insisted on it, so I'll be using that for the first time in the next few weeks. I'm interested to see how that goes.

    After starting out using so much AB, I feel spoiled now being able to build a wall more than one course at a time without having to backfill.

    I hear that. We normally use Keystone for larger builds, and usually backfill every 3. Saves a ton of time. As stated though, every block has its good and bad points. :)
