Rising damp wall

Question

Some mild rising damp identified on internal walls. Builder has slabbed directly to wall. Damp proofer advised wall should have pressure treated timber Barton before board went on. Which is better?
Will putting board to wall cause more damp as there is no cavity for wall to breathe?

Wayne · Answer

Yes it's never practical to slab right up to wall. You should be 50cm to 100cm away from the wall fill with pea gravel. Also 150cm lower than the damp course

Matthew · Answer

Yes putting boards up towards it would just course further issue in a later date

If you’re installing dry rods into the affected walls you don’t need too. Check out a dry zone system/ safeguard.  ( YouTube )
Make sure you’re correct in determining “rising damp” by getting a damp survey.
Not saying it’s the wrong way however you can reduce room size by batten and board and create more work.

Dean · Answer

Builder has formed a damp bridge , boards will need cutting so theres a gap to allow wall to breath

Fatmir · Answer

there are other ways but this will also reduce humidity

Barry · Answer

Yes putting board straight to wall will not help, either the treated timber first or apply sand and cement to the wall will help also, but would try to stop the damp from the outside.

Danny · Answer

This is correct this will ensure any damp environment will be cured and root cause identified and treated.
