This is the one I bought, though as you'd expect there are tons of other choices on Amazon.

I just got it so am not sure what my method will be for when it gets a lot of water on it. It will be easy enough to drag it outside and lift one end to drain it, but that might create an icy driveway. The heater in my garage blows pretty hard so it should help evaporate a fair amount of water, but if it gets really full that could take a while. So not really sure. It may not be an ideal solution, but I still like it better than standing water eating away at the bottom of my garage walls and some cabinets etc. I have in there. So far not an ounce of water has escaped from it, so overall a win.
