Magnetic Damp Proof Course

Has anyone had any experience with this method? It's non invasive so I'm just wondering why it isn't offered as a method of damp proofing after having a damp survey conducted. Thanks in advance.

Yes, I used one in an old Cotswold stone building, the firm 'Rentokil' did it and it worked well.

They drill a series of holes in the wall and loop a bronze wire in & out around the building. 

I'm not sure of the science, but it produces some kind of a static electric field between the loops.

Kitty, I imagine this is connected to your flaking emulsion we talked about in July?

Every now and then, someone will come up with yey another 'cure-all' for perceived dampness in masonry.  Back in the 70s, I worked on re-plastering after a supposed treatment for 'osmosis', i.e. damp creeping up walls. It involved a transformer inducing a potential difference (voltage) in  masonry.

At the same time, 'Rentokil' were advocating their 'single wire' system which was supposed to carry unwanted micro-voltages away from walls to earth. Apparently, these voltages attracted damp creep.

It wasn't many years before these money-making treatments lost favour... and credibility.

MOST damp problems are not rising damp. They may, or may not be only a small part of the issue.

And now someone's come up with the latest scheme.  😫

That's the one, K.

That takes me back. Often, if the damp is alleviated, then it was most likely for other reasons entirely. The thing is, we never know for sure if the 'remedy' was valid. That's what these schemes rely on.
