Hi, Just wanted to come back to this thread to update everyone. I blocked the outside vent holes with strips of foam and taped over it as well for good measure, and 10 days later the moisture coming into the room has stopped completely. This is after a good few months of a small...

Hi Woody, I do appreciate that, but water running down the inside face of the outside wall isn't the issue here so much as water getting on the 'other side' of a DPC membrane running down that same wall. I think it's right to make that distinction here, given that the builder has made...

Thanks again guys for your input and advice, Oldun, I think I should probably have shown the concrete floor insulation between the floor DPC and the concrete, so that's my fault for missing it off the original drawing rather than it being missed during the build. I was concentrating on...

Hi John, Do you mean just through the brickwork, perhaps under the DPC ? What makes you think that the cavity is filled with water ? The moisture is very localised, with a run of about 350mm along the internal area of the two DPC membranes, and that's the only place where this extra DPC...

Oldun, Thanks very much for taking the time with your really insightful post, especially where it's educating a non-builder-type such as myself, it's always nice to be able to learn something along the way with these things. I'm very glad that it looks like the bricks are ok for the job...

Back again after doing some digging over brick-data. It's amazing what you learn when you're given some pointers, so thanks for asking about the Carltons ! It seems that all bricks below DPC must be F2 graded for frost-resistance, and I guess some sort of low water-retention, is that correct...

Hi, I've absolutely no idea, and this is the first time I've actually thought about it. You're right that they're perforated bricks though. Is this just a general question, or do you think it could have some bearing on the moisture issue ? Given that I've got what looks like a DPC...

Hi John, Yes, the older looking bricks are on the rear wall to the house, where the extension was built from. They look worse due to the build I think, they're really not 'that' bad. :O) Cheers, Isitwinteralready

Hi John, The first picture I posted was a rough idea of what the DPC sheeting was supposed to allow me to do, to raise the external ground level higher than the first (lower) DPC and stop moisture ingress through that particular part of the wall. The higher external DPC 'lip' is actually...

Thanks for the reply, much appreciated. Not sure I can answer all your questions without asking the builder, and that's not possible right now, but the external skin is brickwork, not sure of the type, but they're a mottled type like these :-...

Hi, A recent extension on the back of my house is having some issues with moisture weeping into the building at floor level between two DPC membranes in the internal wall. Whilst we're still investigating just what the cause can be with the builder, who I must say was superb throughout...
