Rising damp or Condensation ?
This is always the question and it courts controversy, some say Rising damp doesn’t exist ! If that’s the case then why do building regulations insist on a damp proof course (DPC), why do the British standards institute produce documents relating to both identification and remediation? Why do the BRE allow you to purchase leaflets and documents detailing the correct way to treat it ?
So there is a good chance that it does exist and commonly present in properties built prior to the 1890s. The real issue is misdiagnosis, a lack of knowledge and skill within the damp proofing industry leads to many being seen as just salesmen trying to push their bogus wares !
The new Buzz work for the last few years has been interstitial condensation. This in its most basic form is where water in vapour form migrates through the fabric of a building and at some point cools enough to turn back to water . This same issue can occur internally where normal condensation finds a damp wall, which by its nature will be colder, and it condenses there exasperating the existing structural dampness.
All sounds very complicated I know, well we don’t guess and we don’t misdiagnose we look for any factors that could be creating an issue (failed rainwater goods, poor drainage, high internal condensation issues). We test walls both on the surface and at depth, complete salt tests and speedy carbide tests where necessary and look at the big picture not just a few stains on your wall.
