    Anyone hear of 6M rock and can it be subsituted for 57# rock. Size is around 1"~1 1/2" in diameter. Supplier said it won't be a problem, but a second oppinion is would be nice. Wall is around 4' tall at highest point.

    You need to be more specific.

    What exactly are you considering using such a product for? 1.5" drainage rock is typically used in leach fields for septic systems.

    Sounds like you wanna use it for the wall's drainage chimney??

    If so, it probably will be ok. Buy if 3/4-inch is avaiable, then use a proven material.

    One thing I didn't do is wash the rock. Would that pose a problem in the future? Although, I did flush it for a long time when I checked my work.
