I have read a little about them in a magazine. They seem like a great system, and very aesthetic too. Any idea on a price ?
I assume they are going to be pricey. There would be some savings from not needing geogrid. Also the blocks have a slot to run the drain pipe thru them resulting in not needing stone in the wall & behind the wall.I have read a little about them in a magazine.

The developer I'm working for is making final call on the block. We have been working for them for over 20 years. One thing I know about him is that he reviews & studies things very carefully before make decisions. He also doesn't mind spending more money if it seems like a superior product.Make sure there is sufficient back-up and testing to satisfy the codes. Typically, these type of systems are big and heavy and lack of real testing and approvals for approvals. They represent a very small portion of the market, especially when it comes to high walls.
Nothing is worse than committing to a project relying on unproven gravity systems when you are geared up and ready to go.
LittleLittle1. How big a crew did you have & what type of equipment?
One operator, 2 laborers, 312 excavator but could def use something smaller
2. How many sq ft. was the wall you did & how long did it take?
I was averaging about 200sf per day but this was a wall with half straight half curved. Also about half was the 24sf blocks and other half was 6sf/3sf blocks
3. Have you used other block before & how did it cost/ sq ft compare?
I don't have cost of doing the an allenblock style wall, but def get more done with the stone strong, the base course of the stone strong has to be pretty much perfect though as once you get to the next or third course there is no fixing any gaps that start to occur (mismatches in the blocks). We have done plenty of allen block walls and usually require one operator/machine, 3 or 4 laborers.
4. Did you measure setback block by block or could you use a chalk line to establish setback.
You could use a chalk line on a totally straight run.
Hope this helps a little bit. Their claim of installing 2000sf a day with one operator/machine and one laborer is absurd, hehe. Maybe after you got used to installing the wall and you had a guy that really hustled with one other guy.
I hear where you are coming from Pipeguy. The developer has left the decision up to me because he is comfortable with either system. We have worked with this guy for a long time and he is more of a numbers guy than field guy. If the wall system were to fail I know the engineers would point at me. That why we will have daily inspections and any other safeguards I can think of to cover my tail. I am leaning towards the versablock wall system anyway. They will supply & install the wall for $10/sf. I will excavate, backfill & compact. Stone strong system costs $18/sf for block alone. Seems too pricey considering I don't think I could enough sf to make up cost difference. The worst part of the whole wall is that very little will be seen considering all the wetlands it is crossing and the future overgrowth of brush. I wish they made a more inexpensive block w/o finished face.UPCHUCK-
I got a "WARNING WILL ROBINSON" feeling when I read this thread. In late August you noted "One thing I know about him is that he reviews & studies things very carefully before make decisions." Here it is October and you're finding "The developer has left the decision to me." What I "hear" in that is the developer has studied it and decided it's best someone else make the decision - that seems peculiar.
My experience with issues like this is that you can have all the stamps and calculations in the world and the bottom line is if the system fails the guy what built it is the first guy taking a hit; maybe the only one if the engineer has its way. In most cases its a tough (if not impossible) road to hoe for an installer to prove it has no culpability in the failure of an installed system. If it were me I'd want some substantial $$incentive from the wall system guy before I put my arse on the line for both spec'ing and building the wall.
