If you are about to convert an old barn into living accommodations, then this video is for you. We discuss some of the DOs and DON'Ts in regards to dealing with the dampness, ground salts and renovation issues.
00:01 Overview of a typical old farm building
01:45 Condition of floors
02:55 Walls - why ground salts can be a problem?
08:00 Technical salts measurements: how to assess the amount of salts
12:30 Conclusions
13:10 How to renovate correctly and what to avoid: correct and incorrect way of renovating
This is the best and most simply education about damp proofing out there. Thank you. No waffle, just straight talk and very helpful. I have confidence in ridding myself of any damp problem i encounter in walls. Great.
Thank you, I'm glad you liked it.
Very informative and educational I learned quite a lot from your presentation. I appreciate how you described the building issues and the problems that can occur from the condition of the structure
Brilliant, thanks so much for this.
Man that is an amazing building!
This is very interesting. I just wish my stepfather knew about this when I was a kid. He always thought he knew what he was doing even though all our walls were damp and we had all kinds of crap growing on them.
What a brilliant video, thank you👍🏼
Quality presentation.
well done .
great explanation and video
Great tips, thank you!
That is a nice place. Hope it is being restored now.
Brilliant video. Thank you!
Glad it was helpful!
does it help at all to pressure wash the brickwork
Hi, was it normal rinzaffo you were referring to, or a special kind of rinzaffo?

What about some horizontal barrier to prevent caplary damp to rise.
Or it's doable without it?
And how would you make a flooring here?
Here are described the various DPC technologies and their historical evolution. www.coreconservation.co.uk/solving-rising-damp/#t-161564109639
Based on our research on breathability, moisture accumulates even in a totally breathable masonry due to the presence of surface energies (tiny electrostatic charges present on every solid surface) and rising damp can develop over time even if the wall fabric is kept breathable.

Having a damp proof course can prevent that from happening.
Hack off the plastering then pressure wash the brick work down then lay a membrane and concrete floor and brick the wall back and plaster the rooms out do the wood work job's and then happy days
The problem with this approach is that by washing down the walls you dilute and spread all the salts through the brickwork. Upon the evaporation of the water the salts will recrystallize behind/into the plaster, creating problems shortly thereafter.
Re the floor: the membrane and concrete floor approach would work for the floor, but how about its effect to the walls? Closing off the floor will also have an effect onto the walls, it will make rising damp worse as all moisture will force-evaporate though the walls, which will ultimately damage the plaster.
For plastering: if you apply non-breathable cement, that will damage the brickwork. If you apply a lime plaster, that will buffer the salts for a few years, then the crystallizing salts will break down the lime - unless you use a salt-resistant lime base coat under your main lime coat to mitigate the destructive effect of salts.
Wrong, the salts are in the soil under the wall. It will take years to draw it all out. You could inject a plastic dpc into the lowest part of the wall, but then you still have the salts in the wall above. To follow your plan - you would have to flush out the salts and rely on rising damp and the wall to breath out the last salt, as the plastic dpc would prevent rising damp to work in your favour of flushing, then one would have to pump clean water into the wall (above the plastic dpc) and draw out salts that way. Trust me I know. You need to learn Flash, learn a trade. Your method would fail and new plaster would fall off and paintwork ruined by salt. No happy days for you....woodwork jobs, not wood work job's, please learn English if you wish to settle here. And learn a trade.
