Did they do any re-plastering

It should have been injected into the mortar bed not granite! What did they do?

So you still have a damp wall, post a pic and lets discuss

Why do you want to know how old I am? I thought we were talking about damp lol

When you say it's **** , what do you mean?

Its not a copy and paste, this is the basics of any damp diagnosis that was taught to me years ago, SALTS! Did you read the below link? Sampling for Moisture and Soluble Salt 'Profiles' This is what is taught as a basic of understanding of dampness and salt distribution, I hope this helps! No...

Irish Spread read this.......you may understand after reading this about rising damp and salts, and also why Bre digest 245 is used Sampling for Moisture and Soluble Salt 'Profiles'

I see it on a regular basis 2, a local authority had a terrace of houses (3) with a suspended floors that had a nasty dry rot outbreak. Anyway the floors were removed dry rot treated and they replaced the floors with concrete and insulation...... they then all got rising damp lol The dynamics of...

You certainly show that you don't understand the distribution of salts which are left at the height of rise. Nitrates and chlorides distributed in a salt band at for example 1m, none above and none below, these are hygroscopic! How did they get there if there is no such thing as rising damp...

Why would you need an electrical conductivity meter if you don't believe in rising damp lol Why do you get a salt band at the height of rise then, if there is no such thing as rising damp? Many laboratory studies!!!! Bre Digest 245 is used in court to prove if there is a damp or rising damp...

EXACTLY, ITS TOTAL MOISTURE CONTENT. That is hygroscopic salt and free moisture, so its a waste of time on site and proves nothing.

So what wme do you use for rising damp?

Rising damp doesn't occur from an internal bridged cavity then if its built with bricks? Rising damp in a brick for you https://www.youtube.com/watch?v=aGlRDZo2_Eo

irish spread I'm still laughing........ it can rise through an external brick but not an internal lmfao BRE LOVE PEOPLE LIKE YOU :RpS_thumbup: NO FACTS LMFAO

The dampness doesn't rise through the bricks.....i laughed so hard I pissed myself! Do you know the pore size of a brick? Im not talking of an engineering brick.... So it can rise through bonding but not a brick lmfao

You have never seen a bridged cavity causing rising damp? I have lol

Do you mean profile by gravimetric or wme ?

When you say a profile, what do you mean? By gravimetric or wme?

So a bridged dpc in the cavity is causing rising damp then.... No its not rising damp then...what is it then?

Bridged DPC, Is that rising damp then? Its a bridged cavity!

"a lot of the time bridged dpc" what does that mean then?

"a lot of the time bridged dpc" what does that mean then?

You have never seen rising damp

you have never seen rising damp

yes but its a qualitative reading in timber, so what do use in masonry for wme irish spread?

yes but its a qualitative reading in timber, so what do use in masonry for wme irish spread?

I like the survey master, its a good meter, what wme do you use though on walls to say if it has rising damp or not. Im not a member of the PCA.

lol Perhaps you could provide some of your experience on the question?

Please don't take offence, like I said before I have no doubt in your ability, and that you take pride in your work! As above this forum is for learning, thats why I have asked you, what wme do you use for diagnosing rising damp? I do find it strange that you never answer a question...

BITE BITE BITE Answer the question, what wme do you use? Im sure this would make an interesting topic that everyone can learn from to be fair. :RpS_thumbsup:

Read what I quoted, My dad is an architect, so I have been fortunate to learn building pathology from him which is something you can't buy or learn from a book. I also have the CSRT and CSSW, its not just a piece of paper. I say it again, I'm not a PCA member I just have the qualifications. I...

I never said I was a member of the PCA my friend, as i'm not, I've done the training that is all Just answer his question. Surely you do a condensation survey before assuming its rising damp, right?

BITE BITE BITE Answer the question, what wme do you use? Yes of course I have done the treatments, its all part of the job.

I got a stickle back caught in my jap eye so I'm a better damp proofer than you

DON'T BITE LOL We have now worked out you have no PI insurance you can't offer an insurance backed guarantee and no cpd, and all architects design cock ups, and not to forget you inject anti sulphate into perps of stone to stop hygroscopic salts. Oh and you also hate the PCA! Adapt I never...

They will not send free products as the products will not fail if installed correctly, so they say :-) The PCA is a great organisation and focussed on training, fair enough if you don't want to learn from some of the best in the industry. The way I look at things is different to you, I want to...

I thought you meant that lime render would not crack if a building moved an inch and sand and cement would? confused lol

Sorry, I thought you meant that lime render would not crack if a building moved an inch and sand and cement would? Do you use tanking and guarantee it then below ground?

Your points about lime pointing-mortar are very true and I personally love working with lime, it is a fantastic product. The majority of shrinkable clays are in the South East which covers London that is where most of the subsidence work is, I didn't know that lime doesn't crack if a building...

LTD is the way forward, but you can't shut down knowingly if you have a claim and move money...you will be liable. Sand and cement if applied correctly will last longer than a 20 year guarantee. If you apply a lime plaster and guarantee it with a remedial dpc you could get into a claim through...

@adapt you said "If your thinking of getting into remedial works remember that you could end up losing your house over a failed job, it does happen" How do you protect against failure of your work then if you don't offer an insurance backed guarantee, I'm confused lol

Hi Perlite Yes, all on commission FACT :)

The guarantee companies will not help you when your in the ****!!! When they make you an approved contractor on a 1 day course, they don't make you a surveyor, but most of all they don't teach you about the legal implications of a survey or remedial works. Even if you don't guarantee your work...

@adapt you said "Damp proofing guarantees are actually only good for as long as the company trades" "I know of a certain company issuing 30 year guarantee's and the owner is 65+ so I would say them bits of paper are going to be worthless that he is issuing now" An Insurance backed guarantee...

The reason I ask is because they look high, do they come through and go below the sub floor? To have an infestation or decay of the sub floor where you need to rip the lot out is because of the high moisture content of the timbers. So simply replacing the floor isn't fixing the problem.....it...

Have you installed the sub floor vents?

I just looked at your pics, the ground level is high and a bridging plinth with sub floor ventilation 1ft up the wall.....no wonder it was damp, looks like its pointed with s&c would be a better job if it was lime! The chances of that wall drying down will take a long time, it will also be cold...

Read this link, its got some good content. If you get involved with damp repairs you should state that may have problems with salt damage, if you do a job with a conservation officer make sure you get them to give you the spec and tell the client the risks of salt contamination....this will...

Sorry I didn't know it was a cavity wall! There is no reason to tank a cavity wall still though, penetration from a gutter leak wouldn't normally come through to the internal skin. If it was the first thing is good diagnosis. If you are not a specialist in damp diagnosis it is best to leave it...

@perlite Mike Adams wrote "The walls in question where stripped of all wallpaper and pva'd then skimmed" If the wall paper was wetted or steamed to be removed this can mobilise salts in the wall, same as when using lime mortar, you wet the walls down which can then bring salts to the surface...
