ᐅ Electro-osmosis for drying out damp walls

Hello everyone

Our house is almost 200 years old. It still has 80cm (31.5 inches) sandstone walls that were very damp when we bought it in 1983. There is no basement. Groundwater is already 1m (3.3 feet) below the surface.

Copper wires were installed every 40cm (16 inches) in the foundation from the outside and connected around the entire house with a copper wire. At each corner of the house, a 1m (3.3 feet) iron pipe was driven into the ground and connected to the wires.

After about 3 years, everything was dry. I removed the plaster and replastered it.

Best regards

Hello Hertweck, there is a lot of nonsense written, also in the literature. The main point is definitely that you should buy it.... At least, I am familiar with several books and authors on the topic. The artificially exaggerated controversy about electroosmosis, which has actually been settled for a long time, has a different background. Even scientists tend to be forgotten.... :-)

Incidentally, electroosmosis can be seen as the movement from anode to cathode, but also as the fact that nothing more migrates to the permanent positive pole.... And that is exactly the secret of the matter. We are not interested in how much or how fast moisture moves toward the cathode, but in the described reverse process of the permanent potential reversal of the masonry.

Due to the minimally controlled residual moisture from the control device, the current flow in the masonry is permanently maintained at just a few percent household moisture, it never fails, and thus continuously keeps rising moisture away. So it is nonsense when it is claimed... wet-dry-wet-dry.

Such a system can also operate with only 10% residual moisture if used correctly. Or where is it written that higher moisture is needed to ensure a current flow?

By the way, I have been successfully working with this method since the 1990s. If it did not work, I would have long ago been out of business with the product, the company, and the reputation. It is strange that my success proves the complete opposite of the negative propaganda about electroosmosis.

And one final word on the subject...
Besides, anyone can already see that we are not retirement scammers on a promotional tour, but have been working for decades with internationally renowned clients. These contracts are always tendered and supervised by civil engineers and others, which you are surely well aware of.
You also know that the procedure has been standardized for many years.
So I just wonder what "NEW" has been discovered today with one or two contradictory new opinions from scientists who apparently want to make themselves seem important.
Do you mean that all previous tests and evaluations by other scientists are now questionable, inferior, or even incorrect?
Incidentally, even the VDI Germany recommends the process of active electroosmosis.
Association of German Engineers.

A brief clarification:
The VDI does not recommend electroosmosis in the document you linked; it merely presents a company and its product (in this case, "active electroosmosis") in a somewhat indirect manner.

The publication you are quoting from ("Thüringer Mitteilungen") is subtitled "Interviews with Thuringian Companies."

As I said, I am not debating active electroosmosis here on the forum—nor, for that matter, the benefits of well-insulated houses or adequately humidified indoor air.
And anyway: "The point is obviously that you are supposed to buy it...."

Uhm..., "arguments" for insulation nonsense?

Oh dear, the term "insulation nonsense" has been circulating in German-speaking forums for many years now – always the same twisted topics and "arguments." Please do not take this personally; it is only about the content.
