Damp problem

[smithma0]

I have a problem with some damp that's on one of the outside walls of my 15 year old house.

It seems the DPC has been broken (possibly by cable ties) in one corner. Damp has moved up above the DPC and along the wall (you can see the damp on the wall), and the mortar where the water is crossing the layer is crumbling for 30cm or so either side. Also, one brick has 'blown' above the DPC.

There is no damp inside the house.

What should I do? Any advice gratefully received.

Lets start with a couple of pics, much easier to advise on.

Difficult to give detailed advice without proper inspection but if your DPC is compromised I suspect you'll need to get a new one created through injection. That part of the process is quite straightforward, its the hacking off old plaster and re-plastering that is messy.

I'll try and get a pic up tomorrow - at work at the mo.
The inside is dry - I think the real damp is isolated to the point of failure and the damp on the wall in on the outside only.

Thanks.

OK, here's a couple of pics. The wet seems to have dried along the wall a bit since I scraped out some of the loose mortar and removed the cable ties:

Leaking gutter?

Looks like that is at damp-course level. Would just re-point and check for any additional loose pointing while at it. As already said; could be a leaking gutter splashing up onto the brickwork.

Which joint is the DPC at - ground/gravel should be at least 2 bricks below DPC. Is that a downpipe/drain to the right - is it blocked/overflowing and flooding the gravel area/french drain?
