Interesting idea, but will it work?
This will block doors and maybe windows. However the walls of most homes are water resistant, but not waterproof unless they are made of cement or some other solid material. Metal walls are not waterproof. Neither are wood or vinyl walls. Brick walls have multiple leaks. So this is a temporary stop-gap measure at best. Sandbags around a home would be better with best sump pump as backup.
Or if you want to use this idea, than you may also want to coat the exterior of your home with a cement coating of about 1/2″ and part way up to create a wall barrier. I am guessing that the people with spray-on cement from the Dome-Institute projects could accommodate you. (I have no connection to them.)
Another idea may be to create a epoxy/fiberglass barrier along the outside walls of your home which is a few feet high.
Exterior walls should go about a foot or so into the ground so water does not come under your barriers.
And there is nothing wrong with making an earth or sand barrier around your home. Decorate it with flowers. Place a heavy plastic lining under it and between the earth or sand barrier and your home.
I am sure that many people can come up with other ideas…
