"Not a good plan. You might as well just pile the dirt up where you want it. The plastic garbage bags will rip easily, the zombies will just claw holes in the bags and the dirt will just run out to the ground.

If you had some canvas or burlap bags they may work better, just like a sand bag. "

"I heard they teach my method in Greed Beret training, is it true?"

"Homemade Hesco walls:

Measure out 16' lengths of 5' tall wire mesh fencing.

Wrap the fencing into cylinders, using pliers to join the two ends together.

Using tarp or canvas, cut strips the same size as the fence lengths (5'x16') or slightly larger. (Example: if you have a 20x20 tarp, you can get four 5' strips.)

Line the inside of the fence with the tarp. Use tape, zip ties, or tie wire to hold the tarp in place.

Fill the cylinder with dirt, rocks, debris, etc.

Repeat.

"What do you guys think about filling garbage bags with dirt or soil to make barricades."

"The only possible practical usage for this comes from a different survival environment:
nuclear
A large heavy-duty yard bag filled with dirt and placed over basement windows (full or garden basement) or better yet 3-4 of them, will go a long way toward blocking and stopping radiation from the blast. Alpha & beta rays for sure but you need about 4 ft or more of dirt to keep the gamma rays out.
This is considered emergency pre-blast prep if time allows.
Given the nature of nuclear blasts/effects, it's best to be underground and out of the path from the gamma rays (which travel in straight line over the surface).

"the 'soil' you pour into a bag will be loose and actually less potent than wet sand

where is the zombie application again? Barricade?"

"I don't think you will be able to move around a garbage bag full of dirt. It will weigh too much and the bags will rip."
