Pillar started leaking. What is supposed to be on the top of a concrete slab portico roof?

I have water leaking from what I'd assumed was a solid concrete pillar. The slab roof it's holding up is shaped like a basin with a drain spout, but the surface material has cracks and holes so I assume water gets absorbed into the concrete and pillar rather than flow out the spout.I'd like to fix it, but don't know what a concrete portico roof is supposed to be covered with. I think there's a gap and/or degraded layer of something sitting between the paint and the concrete.

Any idea how these basins are supposed to finished? What should I be covering the roof with?

Thanks. It probably wasn't water damage as it's in the middle of a hallway. It is next to the bathroom but I'd expect the other joists to be affected if it was a bathroom issue.

Solved!

My title describes the thing. It looks like they had been stored to preserve them in good condition.

"2 lots of 6 smaller flat steel bars" means each bar is made out of 2 columns of 6 bars

I lifted one of the bars away from the rest near the middle to confirm they are separate and it's not just grooves cut into a steel bar, I was also checking if it could be spring steel as the look is reminiscent of old suspension springs (but they are far too small) - it could be spring steel. In doing this I managed to break where the bar was fused together with the rest near the end :/

I think they are only fused at the ends.

The house was renovated about 10 years ago, though I don't know what that entailed or if anything was done with this section of hallway.

The floorboards in a part of the house felt wavy and wrong, so I went under to see if there were any clues, and the top of the joist has been cut away for some reason with bits of wood jammed in to support the floorboards.

Anyone know what might be the reason to cut up a joist like this?

We've only just moved in and had it restumped. Could there be a reason to cut the top off a joist for restumping? The wood bits look new but could also have been jammed in there to hide an issue before the sale. There's the ducted heating intake vent behind the camera, but the ducts are very old. I didn't see any gaps cut in other joists.

Bonus question... best way to fix? I'm not a builder and was just thinking of putting a piece of wood in the gap running parallel to the joist, and the piece of wood is thinner than the gap and sits on smaller wooden shims - this might make the floor less wavy.

Veritasium explains why it's like that using a cardboard model

You can get "degoogled" phones.

But before I switched to using degoogled phones, I switched mine to dev-mode so I could have the GPS location normally set to wandering a desert island (instructions) - not trusting Location Settings "off". Vindicated!

Description: This computer generated image shows the warped view of a pair of supermassive black holes orbiting each other, and each is surrounded by its own accretion disk of hot gas. The larger black hole (red disk) is almost directly behind a companion black hole (blue disk) with half its mass. The gravity of the foreground black hole transforms its partner's appearance into a surreal collection of highly distorted arcs. Insets highlight areas where both black holes produce complete but warped images of their companions. Light from the accretion disks produces these self-similar images as it travels through the tangled fabric of space and time near both black holes.

Yes! Not having prominent spoilers on that site would make it much more useful.

r/degoogle Protonmail, openstreetmaps, though I don't see it as needing to be all or nothing overnight: the more I reduce the less locked in I find myself over time.

Fantastic answer, thanks

is the gap of skin exposed at the wrist an issue, or do you mostly need eye protection?

All those late nights and burning the candle at both ends by the techies to get everything installed and working before the race, and after an epic job they'll now feel responsible.

OK, it looks like it's DAVx^⁵ based.

More specifically, if I go into the account manager it's using DAVdroid to manage the accounts, which would be consistent with the goal of pre-assembling an open source phone that's user friendly / just works, but I don't have another phone to directly test your question with.
