Hi,
we seem to have small patches of damp it seems on a wall which isnt linked to anything, it open on the other side. its a semi detached house. the wall has been newly painted.
the outside floor was raised but is still around 10-15cm lower then the damp proof corse only problem is that the damp proof wall/thing has green stuff on it.
it does have air bricked down the bottom but we not sure if there blocked or not.
can any suggest what the problem might be,
i will add pics later on.
thanks in advance.

anyone have any ideas0

It's got to be coming from somewhere. Any blocked/leaking gutters/downpipes anywhere? over flowing Water butt? Anything bridging the damp proof course? Walls etc?
Going out and having a look when it's chucking it down might be helpful.0 -
Looks as though the exterior rendering has bridged the damp proof course. If so simplest solution is to remove the rendering to above the dpc.0

I can't see properly because the pictures are so massive!
Can you make the pictures a lot smaller or just link to where you've kept them?Everything that is supposed to be in heaven is already here on earth.

ive cut the pictues down,
i though the line tht you see is the dpc and below that is nothing
theres no drainage stuff here so no blockage only problem is that rain water cant escape as theres no drainage along the side of the house. only another house around a metre away0 -
Does rainwater run into the holes in the airbrick?
SDPlanning on starting the GC again soon

not too sure about, it shouldnt do but we will check when it rain heavy.
is the damp proofing the part which is slightly out on the outside pictures.
a neighbour said the old owner raised the floor above the DPC but it doesnt seem like that when we look at it.
he also said he may have raised the floor and then put the DPC on which is confusing
thanka again for the info0 -
Forgot to add unless the air brick is for ventilation of a pantry or under the stairs.0

here are a few more pictures, we have managed to clear up the bottom air blocks.
as you can see from the pictures there are some airblocks at the top on each room too, this i think if for air circulation.
can anyone tell me what else could be the problem could the wall be soaking in water.
no water goes in through the air brickes but they were slightly blocked and we managed to clean them up
thanks in advance
