That is an oil absorbent material designed to catch oil drips there instead of onto the garage floor.

I replaced mine with matting from the auto parts store and just cut it to fit. Can't remember how much it was but it wasn't to expensive. $10 or so for a roll...

I hadn't really thought about water absorbing but water evaporates. Oil floats on water so that makes it self cleaning... :19:
