I THINK I may have found something. Ordered some Dye to prove it. Here's what I think is happening... Today I decided to hose down the outside of the lane wall - underneath was damp and showed water track marks as usual. Someone turned up - so I stopped hosing and spoke to them for 15 minutes. I then went underneath and it was I THINK far more clamy and damp on the ceiling. Whilst all track marks (apart from 1) seem to go to the edges and the water appears to come in above the original slab and in the 'void' i.e. where the insulation is ; got me thinking.... The below ground blocks etc. were all poured as one. But the 100mm slab and 35mm reinforced concrete were done after. What's to stop a hairline crack being between these separate pours? . There's no detail in the architects design for this. But at the edges what stops water getting 'in-between' the layers?

To be honest ( from memory ) i’m Fairly certain that corner has always had that fault and track . Tried to find an old photo but couldn’t . I’m 99% sure the corner ‘leaked’ when just the slab was down . Obviously as I had holes everywhere I didn’t worry about it

Refitted 2 frames with structual silicone . Although external timber in the upstand for peace of mind treated them

That slabs been there for 3 years ! Surely it’s cured by now ? ?

Did polythene test over largest ‘leak’ Took it off today - water track the same ?

I know ?

Lol irony !

More interesting than Brexit ffs news / mess / joke .

Discrete changes I just do . if a neighbor complains then I have an issue .

A fine view from beneath!

Walk on glass where ??

Yeah structural silicone. probably worrying over nothing ....

I just assumed as you walk on it the sealant would ‘ give ‘ ....

Going to consider it condensation as can't find any leak any where. So will continue as is !

Yes ! More saga ? My upstands were dead level . Now the bitumen and felt are done it would seem a corner is maybe 5mm higher than the other side . So my glazing frame wouldn’t be level . Do I just pack the low side with plastic shims then put tons of structural silicone over them? . Just worried that the structural silicone will ‘give’ as it should and a 100kg + piece of glass is supported just by plastic shims

“Mortgage fraud “ While a correct term - you are “lieing” to take on debt . We all ‘bend’ the truth sometimes. You are not stealing but bending to borrow . Doesn’t mean it’s for everyone! Plenty of people lie to ‘gain’ . ”creative accounting “ is an expression that springs to mind .... Just my view .

Tileflair more like TileDespair !

Just been in there asking about 20mm porcelain tiles on tile pedestals. ” Sir , i’ve Been here 14 years and never heard of such a system ; you need to stick them down and grout “ We left ....

Tempted to dry it out . Then at night leave my Mac there recording the ceiling ..... My gut instinct says it won’t run from corner to edge I.e track . It will appear in ‘patches’ . But that’s just my gut feeling ! ( which I guess suggests condensation)

Lifted up the new cover with PIR as @jamiehamy suggested . Felt over lapping upstand bone dry .

I think Monday I might angle grind those slots wider and deeper . If it appears on both sides I.e same as it is does that prove condensation??

Well . Today looks pretty much the same even with the new cover and angle grinder marks . Doesn’t seem as wet though . Can see my breathe down here but ONLY in the front bit where those 2 skylights are that ‘leak’. What does any of this prove ?

What about that walk on glazing ? ?

Roofers been He said if the building was above ground he’d be 90% sure it was condensation. He said to water proof ( I assume tank ) the cracks at the corners . Then if still moisture in the same place must be condensation..... The other thing of note is if a ‘leak’ you would assume worse with more rain and extreme weather . Yet it’s pretty much constant .

Funnily enough I have seen in the past the entire ceiling covered in droplets . Should of taken a photo . The weather and air flow especially below ground must play some part in all of this . Constructed a ‘cover’ as just suggest . Just waiting for roofer to view before I install .
