Ofcourse a 5 meter tall concrete wall would be ideal but good luck building that in the middle of the apocalypse. What do you feel like would be the next best option?
My personal choice currently would be to find rolls of 2 meters tall steel wire fence, locate a secluded hilltop somewhere in the woods near water and pull the fence tight between living trees and finish it with barbed wire on the top, mostly in case of other survivors trying to sneak in.
I’d start by securing a small, maybe 5m x 5m perimeter as the starting point. This can be accomplished in a day and I now have a safe place to sleep in. When I obtain more fencing I would start building a second layer around the first one with about 3 meters of space in between and as my camp grows and I get more supplies I would just keep building additional layers. If there are longer stretches of fence between trees I would add additional posts as well as 45 degree supports to prevent a horde from pushing it over.
Wire fence like this comes with atleast 2 additional benefits of being able to see thru it as well as enabling you to kill zombies thru it with a spear.
I would think the 5th one (big logs) hopefully you have plentiful lumber to build it. From there you would want to build another about 6 feet behind and fill in between with dirt. Pack it down and it would tolerate the pressure of zombies pushing against it. You would also have a platform above them. This would be very time consuming to build though. As long as you aren’t dealing with fast or smart zombies it should be doable.
How do you move those logs without machinery? Obviously it can be done because thousands of homesteaders did it in the wild West. I just don’t know how they did it.
Pack animals like oxen or mules. Maybe a 2 wheel cart that you put one end on so its easier to drag. Definitely not a job for one person
There’s a few YouTube channels (I don’t have them on hand) where the creators make videos of them using old style tools and methods to move massive materials just by exploiting leverage. It might be of interest to you if you Google it.
Yeah I actually looked it up after posting and they weren’t usually one man jobs. Occasionally they were, but it required creativity and was a laborious task. They used teamwork, leverage, come-alongs, winches, pulleys, and livestock. I have this image in my head of a solo frontiersman building himself a log cabin. I think it’s probably from watching Jeremiah Johnson when I was a kid. It did happen, but it was rare. I suppose if anyone could do it, it would be that tough sumbitch.
