I have abandoned building. People near by throw their trash and government are forcing owners to prevent that. So we figured that out.
Step 1: Making Wooden Shields
So we had premade wooden shields. Not lots of work. there were broken one. So we repaired that.
Step 2: Shielding
So first things first. You have to clear up the space to fit the shield. The shield fits in a burr that are already made. Then you ram a 4"x4" between pillars and nail it to the shield
Step 3: Putting Doors Back In
The doors were knocked out so we brougt "new" ones and put it back together. And no one could open them I hammered them down.
