    This hurrycaine is gonna be the test of everybody's retaining walls.

    And it's gonna generate new work as old walls may collapse.

    I'm just hoping some trees drop and take some concrete and brick with them. Then people get a nice fate insurance check and we go to work

    geez, shooting for the stars down there aren't you. I'm trying to sling some fire wood and maybe cut up a couple branches.... You guys should get it worse though.

    Not to pat myself on the back or anything but I had a sea wall I built take 10" of rain in 8 hours. The lake was up 2' over top of the wall (5' above normal pool). The wall never moved but but there was a "mud slide" that went over the wall and made a huge mess.

    They were very lucky the the dam didn't break on the lake

    personally i dont think versa lok are up to the job they claim to be. look at all the 50-100 year old masonry walls that are tilted from excess forces on them.

    if you do alot of versa lok, you know that you can get higher #s + shorter geogrid with 2a in the backfill zone versus soil, but this is dumb, how much does wet soil weigh vs dry soil? almost double. wet stone vs dry stone, almost no difference

    so 2A gives you higher compaction #s = more friction force but when the soil behind it gets wet and doubles in weight, the stone does not. Personally i like a 12-24" soil layer on top of drainage column on the upper layer of grid to put some weight on it.
