Wet cardboard exposed to Rain

Hello everyone my friends wherever you are on this occasion I will show you some boxes that were previously used as reasons this is wet because of the rain that hit my area

Actually, if the card has been exposed to water, of course it can't be used anymore because it will get better and also hard back when it's dry but the surface isn't good anymore.

The following below are some boxes that had previously been used as a base for seating but now must be moved and replaced with another because it was wet with rain water.
