Hello

I don't understand anything about his idea ...
In addition, our crawl space is not made up of just one room ...

Martian007 that's what I was thinking about (to keep myself from doing it) until I read that, on a crawl space "well done" we place between the screed and the top of the crawl space a barrier against rising moisture in hydraulic cement (waterproofed with Sika products or additives for example). If it is the case of ours I can do it without problem ... but how to know it?

And once again I repeat: there is no way I can intervene from the OUTSIDE !! Please do not insist ... A drain has been placed anyway.

Swift2540, the crawl space is in concrete blocks. I think I will test as you say I also thought about it. Only here is the room above the place where I want to test has a finish in calcium silicate coating (ie there is no less smooth as materials !!!) so it can be very difficult to see if it goes back ... you see it on the photo of the deom here: https://www.econologie.com/forums/auto-insta ... t6030.html

no no not with the room above. What I mean, it is treated only 1/2 height of the breeze blocks of the crawl space. If the upper 1/2 does not get more humid, you have your solution, but if you store the humidity, it will always be contained in the crawl space

[Christophe]

Yes I understood, I was talking in the event that the test would not give anything convincing and or I would treat the entire wall of the crawl space.

I will test at mid height with this product I think: https://www.econologie.info/share/partag ... Z5aXZS.pdf

I have a tar coating in stock but it does not let you breathe ... unlike the white tar of .pdf (it must be the same thing you are talking about). Thanks in any case for sharing your experience!

[swift2540]

No,
I do not know this coating. The one I put on was the white tar brand, and it was ... white
And of course not breathable ...

Hello

Hi bpval
Imagine that your wall is a painting,
You glue the plastic "only" on the picture frame
(you must move the plastic away from the wall)

Ensure rapid drainage of the liquid
in a narrow-entry container (like a bottle)

* Water trapped in the bottle
is off the evaporation / condensation circuit *

A solution that does better than all the money
that you have invested since perpet
and that for almost nothing

It is "The Solution" downstream of the problem
there are no others

Goodbye

Hi HIC

WHAOUUUU!!!

But how do I do for my wall-mounted shelves

And the water from the bottle I can use for pastis

I may not have understood everything yet ...

TODAY I don't want to see that

And, calm down, it's just a little story of pastis
