Brad,
we have never had trouble with critters chewing into the foam. We have lots of muskrats but they seem to leave this foam alone. As to water logging, the type of foam that's specified on the website does not water log. We have had one dock in the water 15 years and we checked the foam's condition when we replaced some decking. It is very hard closed cell foam made for this purpose, so you don't have to be afraid to use it. Best regards..... Hugh
