Can anyone tell me what causes this?

It might be water getting in the cavity through those air-bricks that have been put in and tracking up the wall. There may be a break in the DPC that the water is rising past I would check out what the dpc is made of and if it has broken down anywhere.

I have it on good authority from Softus that there is no such thing as rising damp.

Don't go there!!!

Like you my brick layer under the DPC never really dries out, unless we have a drought and hose ban!

Bet it dried out in the Summer of 76!

What, you mean here.


I don't want to mislead anyone, so I'll state my basic postulate:

Yup - this is deliberately provocative.

Does anyone out there have any real-life examples of rising damp caused ONLY by a failed DPC in the wall? If so, please can you help me understand how it happens/happened?
Rising damp does not exist unless there's a moisture path between one or more of the following:

- floor and inside wall
- plaster and inside wall
- render and outside wall

If you can smell a musty smell of damp then there is a problem.
Odd the way some of the bricks are drying from the ground up but still appear damp below the dpc higher up ! You'd expect the opposite.

Because of the smell, I would suggest you take up the floor in the hall to see what's going on especially check where the joists are sat on the internal walls.

Have a good look at the inside of the wall below the floor near where the car is parked I'm assuming that's the hall.
I suspect the smell may be rotting wood. I hope it isn't.
