We have to add on to an existing SRW. The problem is that I don't know what kind of block it is.

Your mission, if you choose to accept it, is to try and see if my lame description is enough for you to identify the block. Actually there are four different sized blocks and a cap stone.
1. About 7" high and what seems to be 17" wide.
2. About 8 or 9" wide and 7" high.
3. 3.5" high and 8 or 9" wide.
4. not sure (did not have chance to measure) could be the cap stone (brought to me, not measured in field) maybe 2" high and 17" wide.

1, 2, & 3 have triangular voids in them (two in the wide ones), the sides taper back for curved aplications. They are a lip system, what appears to be the top of the face holding back the bottom of the next course (unless I'm upside down). The overall appearance is quite similar to Roman Pisa tumbled look and color.

Any guesses? I usually have my digital, but not today. Any pics or links would be great.

Thanks in advance. I'll try for pictures tomorrow.

Sounds like Allan Block.

That looks to be the one. The only others that are close that I could think of are:

Keystone Country Manor http://www.keystonewalls.com/CM_pages/cm_units.html

or Versa-Lok Mosaic http://www.versa-lok.com/contractor/...ctdescript.htm

But from your description, Allan Block seems like the winner.

I would also vote for Allen Block. Versa-lok has no lips or voids. Another possiblity is Rockwood.

It sure looks like Allen Block is it. They do have a local supplier quite nearby the site as well.

Thanks Digin', and a thank you to all of you for the input and the place to get answers!
