The water resistant chipboard for bathrooms survives wet for ages,

I agree.
Just out of laziness I have had an old sheet of green 18mm chip outside
for the last 3 weeks Of which one weekend was the wettest I have seen
for years. It's resting between the angled drive and the flat flag
stones, and gets used as a spring board on a daily basis.

So far it is holding it's own. has a slight curvature, but no more than
the new stuff I got off Wicks shelves last weekend!
