- A walk through on how I damped proofed the 200 year old house and why I chose tanking instead of injecting.

Thank you so much for watching, I hope you enjoyed the video!
I don't like using modern methods on an old house. It will end up being even more damp. All materials should be breathable.
Hope all is well and thanks for the comment. So far a year on the house is nice and dry on the walls that we have had this done on. Good to hear what others have done on their homes to tackle these issues. Thanks for commenting on the video.
@@houserenovations-tlom7317 In my old house I built a house within the old house. This made the rooms smaller, but it is dry because I have a cavity. I then have the old outer skin and the new inner room. In 1985 I made the mistake of pointing the old stone with portland cement. This cause damage to the stone. I am in the process of replacing this with a feeble lime. The cement was trapping moisture within the wall. Where it touches the wooden windows, because the water cannot get out, it causes the wood to rot.
That’s very interesting about the windows and outer skin. Is that all moisture traveling up from the floor ? As that is a fair way for it to travel up to a window height.
@@houserenovations-tlom7317I have no damp inside the house. For those who do have problems with rising damp, lime will allow the moisture to escape. It's essential that one uses a breathable paint.
@@amyntas97jones29 This is the way apparently - no modern materials, no tanking fluid, no injections...a breathable layer is what is needed. You can even get lime based paint. Sealing the walls will only trap the moisture and cause damage over time.
You need to look at why solid wall construction needs to breath.

Good to get different peoples opinions on it all.
I can report as is fine as we speak.
Really hope it works out for you. But this looks like putting a plaster on an infected cut. The root issue is not being addressed. Why have the walls got damp to start with? I would guess it's many things such as high ground levels outside, lack of ventilation etc
I had a lot of damp in my 1890 house. I found the issue was the ground level around the house was higher than DPC so I dropped it all. Removed all plaster in the house, let it breath then dot and dabbed the whole thing (the walls have a 70mm cavity strangely)
Hi 👋
So far couple of years in and it’s good with the solution that I have done.
All your doing is trapping the moisture IN the wall bud. The bricks Will spall. Just use lime on the older bricks
Hi Neville .
Thanks for your comment and opinion on the matter .
@@houserenovations-tlom7317 Nothing wrong with the workmanship just the material bud
That doesn’t make sense , you would still need to stop the damp from rising .. .
Yep just covering the problem and will make it worse
Hmmm sounds like putting a plaster on the problem, rather than fixing it. Hope you had success anyhow.
Hi Claire , out of interest what would you do to fix it ?
And yeah the areas that have had this done and then boarded over is working great .
@@houserenovations-tlom7317 Hi mate , you sure did take the correct decision with the tanking instead of DPC creams
Hey @@1petrofski , Yeah i am very very pleased with the outcome of this. I havent done this way before but the evidence so far is brilliant. Thanks for watching and speak soon.
Tanking is a short term solution. Not addressing the causes of damp is likely to lead to issues with integrity of your brick walls. While you may feel fine inside your house, the walls will begin to degrade more rapidly. There is a whole world of business which advocates tanking, but it’s a fallacy. The only truly enduring solution it’s to prevent the causes of damp externally and reduce the humidity internally. Btw this is from someone who has tanked a basement and “damp proofed” a ground floor
@@christopherjhallyou are correct. Tanking is a short term solution and acts like a landmine.
Thanks for the video, I'm facing a similar issue and to be honest I'm a little concerned about using cement based products although I probably will because of strength (I need a little reinforcement) and lack of tradesmen skilled with lime mortars/renders. Are you happy with how things turned out? Do you notice any moisture rising up to a higher level in the wall?
I'm considering leaving a few layers of brick exposed on the outside, or even sections of the interior wall with just a lime wash (without plaster/sealing) to promote drying; any advice from the YT community on this one?
Hi Petar ,
I’ve done a few videos on damp related issues in this particular house on the channel which might help further.
This tanking system with the slurry has been very very effective throughout the house and 2 years in it’s worked perfectly.
@@houserenovations-tlom7317 good to hear, I will take a look
I've used tanking slurry and I find it works fine, just follow the instructions. Then we dot and dabbed moisture resistant boards, leaving any timber floors etc at least 25mm away from the plaster, so any weeping, runs down to the subfloor.
@@houserenovations-tlom7317According to a different school of thought that chap with the tanking slurry was taking your money for no good reason.
If I were you, I'd lay dpm on the floor, rake out mortar joint, tuck it in the wall, lay insulation and then underfloor heating with screed. You'll raise the floor a bit but you'll have perfect damp barrier . And ufh as well.
Just don't allow builders to take advantage of you , young man!
All the best!
hey, the tanking slurry has worked a treat with no issues coming through.
Before the UFH was installed the wall was battened with a DPM tucked up behind also for extra protection.
How is it working out for you after couple of years? Any issues???
No issues at all . No damp showing , no smalles no visual issues.
Great demonstration. cheers.
Good to hear from you again Jude.
Thanks for watching.
@@houserenovations-tlom7317 have you looked at Peter ward however he does the opposite. I hope it works out.
Don't look right to me, if it's not getting done the right way it's not worth doing at all, rising damp will course you big problems in the end. What garantee has this method got, nothing in my eyes but good luck to you and don't waste loads of money
Which product was used In the damp n is it suitable for all building?
Hey Abraham , it’s a product from Drybase that was used with all details on the website (safeguardstore.co.uk/drybase-tanking-slurry/?gclid=Cj0KCQjwtvqVBhCVARIsAFUxcRsNLRcaG1jFo_KtcxPConhaC6qYLlVN5AWZYThzIWKXNNVnfdKNo24aAi6iEALw_wcB) .
I would always recommend hiring a professional if you are not sure what you are doing. This also goes for the question about “is it suitable for all buildings” , information is on the website however hire a professional todo it if you are not sure as they can confirm.
Thanks for watching
Completely the wrong strategy! You have suffocated the building in imperious materials ! Damp will appear in the future as structure can't breathe !
Interesting comment and thanks , how long under your theory would it take for the damp to come through you think ?
@@houserenovations-tlom7317 it can be anything from a few weeks to a few years. PLEASE research about breathable materials on old houses. The WORST thing to do is use modern, non breathable materials..the worst being tanking slurry.
This is going to make it worse in the long run. Look for the source to fix the issue.
It’s all good so far.
tanking old bricks, impermeable membranes and gypsum plaster are the WORST things anyone can do to an old building, The bricks must be able to evaporate otherwise they will crumble away.
The external ground level is too high and there is inadequate ventilation within the property causing condensation and moisture trapped within the bricks. There is nothing wrong with the builder's application of the DPC.
Sadly another so called professional who doesn't know anything about pre war houses.
Look at Peter Ward on YT.
Good to hear from you , can you link me the work that you have done on this kind of thing for me to have a look at ?
Always interested in other peoples work.
Too much talking and not enough showing.
Hi mash
Other videos on the channel might be more suited for you in regard to damp control with less talking.
Thanks
