"Rat Walls"
"Rat Walls"
(OP)
OK, I have read everything on thickness of a slab for a light load driveway/garage.
And I apologize for the terminology; my Midwestern family calls it a "Rat Wall". Or a spade depth "footer" dug around the perimeter of a slab.
What I would like to know is the effectiveness of a "Rat Wall". If it is required how deep should I make it and is a spade width sufficient?

I'm not so sure that it is a problem with rodents, I was looking at it more as a structural item.
While yes it is called a "Rat Wall" does it not add stability to the slab?
My father had a pad poured for a shop and they dug the "rat wall" and poured it and the slab at the same time.
Is there a problem with a continuous pour for this? Do I need it?
Thanks

As far as sizing the turndown slab/footing, it is not my place to design it for you. See if someone local can give you a size appropriate for your area and climate.
Good luck,
