I'd like to know as well... I have ~ 90 str, pickaxe and ram, and i've been bashing at this pallisade for an hour now without so much as a change in color, let alone a hole in my wall. Even with Str up at ~ 130 with snuff, it makes no difference.
Does it really take a whole week of constant ramming, or am I just doing something wrong?

I was so excited about finishing my renovations.
