Damp proofing treatment internal walls

This video highlights multiple contributing defects relating to rising damp issues, that need to be addressed before you think about damp proofing walls. If you have damp internal walls, or external walls this video will show you the causes that I found with this particular property.

You as a homeowner can start your own damp survey, and run your taps and check your drains. Wait until it’s raining, and check your gutters. It might be an simple obvious fix.
High ground levels are a common cause of damp issues. Please see my other videos that show you how to lower your high ground levels.
If you have any questions drop them in the comments below.
If you need advice regarding your damp issues give us a shout. If I can’t help you, I can put you in touch with somebody who can ☺
The best tip I can give you is to stay away from cheap non invasive damp surveys as these are a complete waste of time👍

Good Stuff

[@completepreservation]

Thanks 👍

[@jamieshears611]

Brilliant video, as a newly qualified surveyor this is really interesting 👍🏻

[@completepreservation]

Thanks Jamie 👍 I got some to edit that you will hopefully learn something from

[@rozzer666]

You do a really good job. You say it's just basic stuff in almost every video but to the general builder or us home owners it's not basic stuff at all

[@completepreservation]

Thanks for the kind comments bud :)

[@isctony]

Another great video, thanks Ross

[@completepreservation]

That bud...really appreciate the kind comments :)

[@davidcoleman6032]

Brilliant video Ross, again,very interesting. That drain camera looks a great tool,handy when it tells you how far along it's going.🙂👍

[@completepreservation]

Thanks for the kind comment, lots going on with this property. 👍 it’s a great bit of kit bud, I couldn’t be without it 👍

[@RK1Neo]

Spot on as always. Love a mucky video! What were your findings and recommendations on the internal dividing wall?

[@completepreservation]

Thanks bud :) In this case I cut a physical in. The other ones I tanked beneath the physical damp proof course. There was quite a lot of hygroscopic salt present, and the rising damp went quite high. As you can imagine the walls were very wet because of all the defects, thats why it went to a decent height.

Great vid. I got a situation were the corner of the internal wall is damp and the wood skirting is rotten. How can I deal with this. Its going up the wall about 3 foot by 5 foot from corner to middle of wall. Only that section. Can you advise on a solution please or something I can do to resolve.

[@completepreservation]

Thanks for the kind comment 👍 as in this, and other videos on my channel unfortunately it really isn’t always that simple. Go through the basics as per this video below… if that doesn’t help instruct a surveyor to follow the British standards, as per this video. Hope it helps 👍kzbin.info/www/bejne/b2jck5-ugpp8oMU

The "high ground levels" how does cutting a channel around the house stop rain water getting into the foundation? Where does the water go when it's in the channel? It must still seep down?

[@completepreservation]

It helps stop splash over the dpc, and also helps promote evaporation bud. A bit of rain in the channel doesn’t cause an issue, but make sure you don’t have it running off a drive into it 👍

[@Hew.Jarsol]

@@completepreservation Thanks yes I don't have any DPC in my walls as it's old 1800s bit no damp. The walls are up against a soil garden and a cellar underneath. Rain does somehow weep very slowly into the very bottom of the cellar wall (only one wall) when heavy rains.

[@completepreservation]

Check drains, mains, plumbing for leaks and even neighbours can be an issue bud 👍

[@Harryistired]

Great video very useful 👍. What would be your recomended process for diagnosis of damp area to a party wall causing the wallpaper to de-bond in an 1880s mid terrace property . The protimeter is giving high readings and the wall is damp to touch . My thinking is water doesn't appear from nowhere after 140 years of being dry so something must be leaking. The area of the party wall is well away from external walls and no signs of any damp on the neighbours side internally . I've considered getting the services below the suspended timber floor tested i.e. mains water pipe , any drainage , heating pipes and possibly stop-valve under there . Thought this would be the first port of call, don't know if you have any further advice on party walls? Trying to avoid getting the wall "tanked" prior to carrying out all reasonable diagnosis work .

[@completepreservation]

Thanks Harry :) Is it actually wet to the touch bud?

[@Harryistired]

@@completepreservation it's not soaking wet but just feels damp to touch and in conjunction with protimeter readings

[@completepreservation]

Its probably not condensation related then. If you can pick up the floorboard localised to the area and inspect the sub floor. Is there a physical dpc present?

[@k.r.lionheart6460]

Can you put p shingle above a external damp proof course or just below

[@completepreservation]

Just below really bud. Ideally about 150mm below damp proof course 👍

[@steelframe4436]

Thanks for the content, do you have any information on the gravel strip around around a building and can it be replaced with concrete? If DPC is 150mm above and patio falls away from the build if that ok? Thanks

[@completepreservation]

Cheers👍 have a look at this video bud 👍kzbin.info/www/bejne/o2mYm3SgfMiYo9k
