damp courses

[roger.lawrie]

Hi,

We have an old quinta and have noticed small patches of damp on both internal and external walls. We live here year round and heat and air the house daily.
Has anyone similar problems and do you know if an injectable damp course would solve the problem. Would appreciate knowing of reputable companies who carry out such work.

Thanks
Roger.

I have some small damp patches and think that the lack of gutters and the vertical tiling at the base of the external walls doesn't help ie the water rushes off the roof, down the walls and behind the tiles.

Getting some guttering installed (and I remember a thread on the topic)and applying some mastic is on the list of things to do but I'd be interested to hear if anyone's had a damp proof course injected. Suspect there may be a problem with the type of blocks used to construct properties and the plaster (or equivalent).

I think with the type of block used to build in Portugal you wouldn't be able to use the 'typical' injected damp proof, there is no cavity wall. A dehumidifier would probably sort the problem out better.

Thanks for the replies, we have had gutters fitted and use a dehumidifier.
Have seen in local papers about hydropol for damp walls anybody used these? Any help appreciated.
Thanks

I'm not very technical minded, I had the same problem with damp patches and it was found to be caused by old style iron water pipes in the wall corroding and leaking. I had them all replaced with plastic or copper piping and that's done the trick, it wasn't that expensive either

what are your walls made from? stone, block, etc

I,ve had injection dampproofing done in solid stone walls,not cheap but 12 years later still working like a charm. I think as long as the material is some way porous it works fine.You could do it yourself if you had time as it does,nt need a lot of skill or equipment.

[roger.lawrie]

Thanks Gerry for the reply. Can you recommend someone or know where we can buy materials to do this ourselves?

[Gerry Cullen]
