Sandbags wrapped in a tarp would probably do pretty well, then duct tape the seams. That gives you a heavy barrier and a waterproof membrane as well. Keeps it off your walls too, which may or may not let water leak through if there is a reasonable depth of water against them.

But it also depends on your house and the stuff around it. Where I live surface flooding would have to get past my front wall and there is just a narrow path through the brick wall. So sealing there would make the most sense.

At least until it reaches the height for sewers to back up and flow into my house. Then may as well burn it all down and abandon it.
