Hi,

Noticed a strange thing today. There are two shelves in my under
sink cupboard and they are drenched right through the chipboard but
the laminated surfaces are bone dry. I can't seem to find any
leaking pipes, but also I can't work out how to take the units
apart. I live in a housing association property so I'll contact
them in the morning. Just seems odd how the woods wet inside but the
outside is dry.

Is there a cut edge against a damp surface that is acting as a wick,
drawing moisture into the chipboard?

Like the cold rising main on which water can condense?
