I'm trying to build a free-standing fence or barrier that will sit on top of concrete similar to this picture:
The fence I want to build is a bit taller - 6-8ft. Two questions:
How wide does the "feet" of the fence have to be to keep it from falling over in the wind?
I'm thinking about putting support braces in the photo like the picture - do they have to be on both sides of the fence and what size and height does the brace have to be?
