" smart arsed surveyors "
Now we're talking.
And if, for example you did bridge the dpc with render on this cavity wall would the (huge :RpS_lol: ) amount of water that would "rise " up your 25 mm thick render cause the rising dampness you suggest ? I think not.
[h=5]Problems with using external cement based renders[/h][h=5]There was a photo in this post but it don't show in the quick reply box[/h][h=5]This is an extreme example of damp damage - in this case, the stonework of the building has been covered with cement render. This has sealed water into the structure - it has run down the face of the stone, and gone behind the render where it has built up to ridiculously high moisture levels. The only way it can escape is to evaporate out of the stone just above the render, and in so doing, it has destroyed the stone. Note that much of the stone is pointed with cement, which has exacerbated the problem.[/h]In the room inside, the walls are damp as well - moisture has penetrated through the wall and blown the plaster on the inside. All of this render needs to be removed and the stonework requires extensive repair as a result.

The problem nowadays is that people have swallowed all the bull from surveyors and damp companies about this rising damp thing. You need to approach the subject with an open mind and to find what is casing the dampness.
