How can I reduce rain running dow a wall?

[Gary111]

Hi I've got a solid brick wall that seems to get damp and cold.
I had a couple of damp specialists look at it and one suggested putting some cement at an angle at the bottom to help the rain water run away from the building.

I was wondering if I put some kind of canopy / shelter type thing higher up the wall that would be a good idea?

Ideally if I can reduce the rain hitting the wall hopefully it would help.

So would a photo...?

Take the roof off, drop the wall plate by two courses and make your rafters 250mm longer than they are now thus creating a nice soffit overhang with a decent pitch.

Either that of paint some kind of weather-seal solution on the bricks, insulate the external walls (internally) and re-set that window back towards the inside by another 30mm.

@Gary111 damp on the inside or the outside? Seems to or it does? Damp all over the wall or just at the base - otherwise why has someone suggested a concrete fillet a the floor? A bigger overhand will only help the the wall immediately under the eaves any driving rain will still soak the wall, does this wall get much driving rain?

Yes it seems to get the worst of the driving rain, although it's generally a cold flat with a fairly high humidity level.

They suggested that as they thought the amount of water running down was soaking in at the bottom.

I think the area near the door doesn't get much sun also.

Does the fillet seem to be something that might help?

Hi mate I am thinking of doing the fillet this week, whats the usual reason for doing that please ?
I've seen it on a few houses, often painted.

Also it's a concrete floor so I guess that's not helping.

Any advice would be appreciated

Thanks

What are the problems you are trying to address? Is it that inside the room wall is damp to the touch and very cold? If so, let's have a picture of the internal wall.

If these are the problems, then the cause is probably just that the wall and building in general has very poor insulation.

Depends what you want to do - render, waterproof masonry paint, a few coats of Thompsons?

I can't see what a fillet (though I wonder if you mean a plinth?) at the bottom will do except trap water that has soaked into the wall at the bottom -
You really need to establish the existing damp proofing arrangements (wall and internal floor) first.

why would increasing the pitch make any difference ? obviously the longer overhang would be good, but the pitch ?

Just for looks and the fact that it appears under-pitched presently. Ideally you want the soffit board to be hitting the wall at about 2.1 m which is usually at window/door head height.
All that masonry showing above the windows, looks abysmal.

It looks like an old coal bunker or shed that someone's stuck a window in. In which case it will be single-skin brick, with no damp-proofing, and was never intended to be lived in.

The part to the left of the downpipe is a 9" wall, but to the right is probably just single brick width.

Possibly no lintel over the window either, guessing looking at the sagging brick course over it.

If you start investigating improving various bits of it you may well start to wonder which bits are actually worth keeping.
