Corrugated plastic, vs PVC FOAM BOARD?

which would suit my needs better i need something water proof ,something that won't bent or chip or dent easy and something i can easy clean


We cannot have any idea which will better suit YOUR needs unless you explain what your needs are. Both types are susceptible to bending and chipping if not applied properly, particularly at the edges.

the plastic is tougher. with either, you're going to have a water issue at the edges.
