Damp/ pointing HELP

[Smiths2509]

I was just wandering if anyone could offer any advice? I currently have a lot of issue with rising damp (if it's a thing) after fixing the thought to be issue I've notice all the mortar from the bricks missing the dpc flakes of to the bits that still in, is this just a simple case of reappointing and replacing damaged spalled bricks, they are all beneath the dpc which are saturated and spalled. I've uploaded a few pictures incase I have explained it wrong.
Thanks In advance x

I see a downpipe to the left.
When we had this issue (that photo could actually have even ours it’s so similar!) we dug down and the drain gully was an old clay one that had cracked so the ground was constantly sodden causing damp inside. We replaced that and it did dry somewhat but we did then also need to redo the DPC and the pointing before it resolved completely.

Yeah that's all been changed and replaced we had our walls tanked downstairs and chemically injected, but 2 year later we back to the start, although the interior isn't half as bad. It's the entire bottom of the house the whole down stairs. I'm just not sure what the next step would be, it looks like the damp is coming from the inside out which has me baffled
thank you x

Basically, yes. Dig it out deeper though if you can, then you can scrape out the old mortar, an inch is plenty, clean it all, then let it dry. After repoint. You need 3 courses of brickwork under the DPC to be exposed, absolute minimum of 2. Ideally dig a trench a spades width wide and fill it with large pebbles/stones, not pea shingle, up to the bottom of the 3 courses.
Tons of stuff on YouTube about this.

Thank you so much, I'm finding it quite difficult to allow the bricks to become dry, could this kind of problems cause any issues with the foundations?

The white stuff looks like efflorescence. If so, I think it suggests that water is coming from inside.

Have you checked for pipe leaks? If you have a water meter, then leave off all taps (and washing machines etc) for a while and check that the water meter stops.

I'm sure it's also possible that waste pipes leak or that rainwater gets inside the house or inside the wall cavity.

Yeah everything been checked no leaking pipes, the interior isn't half as bad the exterior but maybe that's got something with the tanking?

You can always remove a couple of bricks and let the air flow better in the cavity, could help dry it a bit. In any case, damp beneath the dpc is normal.

Thank you, yeah I understand it's normal for them to damp and the side of the house is they are damp and looks normal, these bricks are saturated and disintegrated in parts the entire mortar x

My uncle worked for Peter Cox a damp proof specialist - he said rising damp doesn't exist and if it did chemical injections certainly weren't the answer, it's all to do with air flow.

Yeah well the chemical injections certainly has not helped here the exterior is far worse then before I got the work done. I'm just worried about it could damage the structures I have a few cracks but not big enough or wide enough to warrant any investigation hoping it's just settlement with it being newly plastered x

The airflow brick with the holes looks a bit blocked up with debris etc maybe clear that out

We have these bricks at the front and back of our house and it seems to help with damp as lots of houses in our area are prone to damp and we don't have any 'rising damp' type of issues

We do have issues with external walls so just keep those clear

We are currently suffering issues however at the top of the house so have had the roof looked at and gutters replaced so now just need to wait

So I feel your utter frustration at not finding a solution to your problem

Also on the side of our house we have a sort of long 1.5 m length by 10cm wide trench / drain that goes into the main outside drain for water run off. It's covered with a metal tray with holes in that we have to remove every so often and clear of debris abs moss that falls from the roof (and also blocks the gutters)

Not entirely sure if that helps particularly but it does something

It's so frustrating it's makes your home lose that homely feel or is that me just being dramatic 🤣 all my pipes and guttering is clear and all replaced and full new gulley. Drain survey showed a crack in the storm pipe so has been realigned.
Hope you've solved your problem, fingers crossed for you x

I’m confused now. What is that last picture and when was it taken?

Sorry I didn't mean to put that picture there the last picture was taken when the gulley was repaired x
