    Okey everyone i stopped by this job this evening and took some more pics. Look at the grid placement, and the un compacted back fill. Also what kind of block is this?

    Block is made by a company called rockwood. The blocks interlock without the use of pins. They work real well if installed correctly. A local contractor here had a large wall fail due to incorrect backfill material also. Seaballast is the best kind of gravel to use to backfill and fill the voids in the blocks. Using shale, SB2, or any material with clay in it due to the fact they do not offer any drainage. Hope this helps

    My sales rep from ab bidded on this job and said it was Keystone. I have never seen a Keystone block is it close to what you are talking about?

    Is it possible they ARE using Keystone and ARE NOT using the pins? That could play a huge role in this failure.

    Could it be?

    [Edit] Nevermind...the closeup of the block does not resemble Keystone and there are no pin holes.

    I've never seen a keystone block to even comment on it.

    The block pictured in championls post is a keystone Standard Unit, they weigh right at 100 pounds. We use them here but we mostly use the keystone compact unit. Keystone makes a great block and we have a great supplier, we are also a distributor for Keystone.
