What kind of floor put on dog kennel? - put a floor in aboat

My dog likes to be left to chew, so we need is a floor under the cage, that 40 "x 80" not to find the chewed apart. Any idea where I can find something like that? I thought of a very thick plastic, like you would break the timber and you do not know how to chew plastic.
