crushed stone size limitation for non-expansive frostfree fi
hi, guys, need help here.
i remember there was a thread before, which discusses about the crushed stone size for use as non-expansive frostfree fill. but i can not find this thread now. can anybody direct me to that thread or tell me what is the max./min. crushed stone size for non-expansive frostfree fill?
thank you very much.
