The hoe and the pick are your friends. You can raise an earthen berm (earthen walls are indestructible) with the hoe and dig a dry moat outside that with the pick. Leave room in the berm for a gate and build a bridge over the moat. Then all you have to do is defend the gate (and there are even tricks to get around that). Your base is safe until you get to one of the late game raids and you can limit the damage from that by building a covered barn for your livestock.

I've done exactly what u wrote about before I wrote on this thread. And as I said trolls and other raiders just kept spawning inside the wall-protected territory. But placing work benches seemed to solve my problem.. sort of

You have to have the work bench coverage to build the berm. As long as you didn't remove the work bench after building the berm you shouldn't have had a problem unless you built so large you had an uncovered hole in the center.
