Water ingress

[andrios79]

Hi there, I have water running down my wall, please see pics.
Cement was originally where the gap is.
A friend said leave open to prevent damp getting behind any obstruction. Though, I feel if left, the water will spread across the wall and worsen. There's some pooling on neighbours side and I have ran some sealant along the base of the wall on the other side. Despite this, the water's still sleeping through. So, my question is, do I fill in the gap with cement as it was in it's original form? Your thoughts will be most welcome. Thanks
Andy

These pictures are of the outside, have you got any of the inside?

The wall is dry and fine on the inside, no damage as of yet ; )
Thanks

Could this be a guttering issue?

Water running down the outside wall, is not an issue.

Not necessarily. We had water running down an outside wall from an overflowing gutter. The water managed to deep behind some lead weathering and then down an inside wall into our kitchen.

That's a fault of the lead not the wall.

Thanks chaps, I think some of the water is coming from the neighbours drive, it's on a slope. And my bottom gutter runs off down into the neighbours run away drain.
As it's only a small gap between the garden wall and house, it's hard to truly ascertain where the water is coming from. I have a video, which shows the problem, but the file is too big. I'll see if I can edit it. Cheers

I didn't blame the wall, the wall was inocent. It was a combined fault. The gutter downpipe was blocked causing the gutter to overflow, and water to cascade down the wall, and the water then compromised the lead work, but my point was, you shouldn't say "Water running down the outside wall, is not an issue", because it could be.

We need either a description of the wall or a photo from further back so we can see the whole of the wall
