What flooring should I use in damp area ?

[Gary111]

My porch floor is particleboard which is sopping wet, rotten.
it is tiled on top.

I need to replace it asap , I'm not sure why it's so wet.
Maybe I need to treat the joists too ?
If so what with ?

What's the most water resistant ?

Should I replace with wooden floorboard ?

Marine ply ?

Water resistant chipboard ?

Thanks

Hi,

Sorry, this might not sound very helpful!
But you really need to sort out the damp problem first!

Ideally you need to understand what is happening; allowing you to cure the problem, or mitigate against it.

Just sweeping the issue under the carpet (or in your case, marine ply ), will eventually lead to failure; then having the expense and hassle of doing it all over again.

I hope that makes sense - post some photos if you can

Take up floor and concrete it .

Find the source of water and repair it.

For example, in a porch it might be rainwater.
