Yep it's them kind of blocks. A good friend is the general for the company who built it. I'm sure I will get more info.asevereid said:Is that a mortarless retaining wall (ie: Alan Block)? That's a massive fix...if they decide to fix it. One would have to remove all of the fill material and block courses down to where it is stable, and then rebuild. But that's a simplistic way of looking at it. A catastrophic failure like that will have to be rebuilt from the ground up. I'd like to see more on this....have any more pics or news reports?
If they are Allan Block products they would be a standard 8"x12"x18" with a certain amount of setback.Its hard to tell, how big do you think each block is?
That's what I thought 2 when I see the pics. I bet water froze behind that wall then rains built up behind it today and it had nowhere to go.tgeb said:Hydro-static pressure. It clearly does not have the proper fill material or drainage system behind the wall.
I know what your talking about.. is it on 46 by the great notch bar ? That wall has to be 100'+ easyIt looks like the tiebacks went with the wall when it failed, they lost 8-10 feet inside the wall.
I have seen a plastic tie back material that was only 7 or 8 feet wide used every few courses but that would not have helped here.
They is a wall twice as high as that in Northern NJ that I could see the same thing happening. Condos are built 25' from the wall.
