    I won't post specific links. Just google that title.

    I don't have any particular need for extra DPC. I just stumbled across this in a recent spam email and I though, "what on earth...?"

    Personally I am sceptical (of course) but I thought a few folks here might like to share the entertainment value.
    Some quotes:-

    Using osmosis a small current positively charges free moisture molecules, which are repelled from the positive anode and attracted to a negative cathode that is buried in the ground, (just as the "poles" of magnets repel or attract each other).

    and

    Ideal for walls up to 600mm thick and for rubble-filled walls, the Lectros Electro Osmotic damp-proofing system is the only dpc treatment that can be installed above timber flooring joists to drive excess moisture down to a level beneath them, fulfilling a vital requirement of a damp-proof course.

    Oh, sorry, I should have searched first.
    I see it's been discussed here before (of course it has).

    I was however quite shocked with the google results... to see the extent to which these things are still being sold all over the place.

    I used to work for a Housing Association. In the early days (early '80s), when refurb standards were pretty basic, a lot of time was spent looking at 'the damp' and trying to disentangle condensation from other forms of damp. We had a few houses with E-O dpcs, and they never seemed to do much. I have not seen them around for years.

    Spent a long time composing those 2 lines(!), so did not see the old links before I posted. Now I have, I propose to trade-mark Biff Vernon's 'dpc method' ( ''You may as well dance widdishens* round the property on a waning moon chanting to the fairies.'') if he'll let me! (Not sure about what guarantee I'll offer, though).

    *a.k.a. 'Widdershins'

    Wikipedia says:

    'Widdershins (sometimes withershins, widershins or widderschynnes) is a term meaning to go counter-clockwise, to go anti-clockwise, or to go lefthandwise, or to walk around an object by always keeping it on the left. i.e. literally, it means to take a course opposite the apparent motion of the sun viewed from the Arctic Circle, (given the centre of this imaginary clock, is the ground, the viewer stands upon).[1] The Oxford English Dictionary's entry cites the earliest uses of the word from 1513, where it was found in the phrase widdersyns start my hair, i.e. my hair stood on end.

    The use of the word also means "in a direction opposite to the usual", and in a direction contrary to the apparent course of the sun. It is cognate with the German language widersinnig, i.e., "against" + "sense". The term "widdershins" was especially common in Lowland Scots.'

    So does widdershins mean clockwise in the southern hemisphere in the same way that veering is to the right in the N and left in the S?

    In this context does it mean bollocks, as in Eco Bollox

    The thing is, they were around long before anything was 'eco', so just plain ....., I guess.

    Was suggested that I fit one to my old Portland Stone place, it had no damp.

    Hundreds of thousands of houses with no d.p.c, but also no damp, have been required, by Building Society surveyors, to inject a d.pc., or use and EO d.p.c. As stated in other traeds, it does not make sense; it ticks boxes.
