patio causing damp in the house

Anonymous user 29/09/2026 - 8.04 AM

hi, The patio at the back of my flat is causing the flat to be damp, it seems to be to high. Can i fix this with a french drain or do i need a whole new patio at a lower level?

Are you a tradesperson and able to answer this question?

Without seeing job. Can't say but its always best to keep it 2 bricks below damp.or leave a 4inch gap between patio and house

It really depends on the existing patio levels and where the damp is coming from. Some Aco/Channel drainage may solve the issue, but if the patio is too high against the property, it may need lowering.

It would be much better to lower the patio finishing 100mm below the damp cource
