concrete humps to block flooding
I've seen them, but no one i know has made one.
Basically, our garage and our back patio flood every time it rains. It starts by pooling on the patio, and then slowly seeps under the back door and part of the wall which faces the patio. In the long run, I am going to replace the door and part of the wall. In the long run we're also going to put a roof over the patio. Because of various reasons we can't do anything of those things right now.
What we want to do is make a concrete hump, close to the door and wall so when the patio floods the garage doesn't. Has anyone else done this before? Any advise? Everyone I've talked to about it has said "oh, that's a great idea" but hasn't done it before...
