Hull integrity

[Bastila Shan]

Why does base hulls decay over time and what can i do to permanently fix it? Reinforce the whole thing?

[Suzaku]

Integrity doesn't decay over time; it decays every time you add a piece to the base, with things like windows reducing it more than other structures. Internal items (like the fabricator, charging stations, furniture, etc) do not reduce integrity.

Add reinforcements to your structures to add a flat increase to your structural integrity.

[Demolition414]

The integrity only decreases when new pieces are added like corridors, windows, ect, but the integrity can be improved with reinforcement panels, and foundations. And to avoid spoilers, theres a scannable item later that increases integrity.

[Bastila Shan]

Integrity seems to decay if you add to another structure thats separate from an existing structure. I added to my docking bay and my other structure nearby started flooding.

[Suzaku]

All structures that are nearby are "linked" as a single base. I don't know what the range is before something becomes it's own base, but just try to reinforce things as you go along, and keep your integrity above 10 so adding something doesn't suddenly result in leaks.

[Bastila Shan]

Is there a way to check current integrity? I dont know when its going to show me integrity level.

[Suzaku]

I'm not sure if there's a way to check without building something. You get all materials back when you disassemble something, so craft a foundation and see what the stats are, then disassemble the foundation if you don't need it.

Found out that there are two things to build inside the base that will lower hull integrity too:
One is the water filtering machine and the other one is the hatch you install on the big fish tank.
I just went and added 4 foundations to my highly instable fishtank base and used them for outdoor gardening. Good place to grow gel-sacks and those blood vines in planter boxes.

As long as your integrity doesn't drop below 0 you should be fine, though I recommend keeping your base integrity at least around 10.

[General Idea]

It's always a good idea to partition your larger bases into sectors with bulkheads sealing off each. That way if you ever have your base hull integrity fall too low without you realising then only a part of the base would flood as a consequence and you can fix that specific location with your repair tool.

bumping into your base with Seamoth/Prawn/Cyclops while integrity is low or subpar will cause damage/flooding.

Reinforcement panels will provide the strongest boost to integrity followed by, Bulkheads which will compartmentalise your base. The Foundation is the weakest for reinforcement and i find it's only real use is for outdoor growbeds or parking your Prawn.

Utilitarian/Minimalist bases generally only require 1-3 reinforcement panels at any depth down to 1km.

The easiest way to check is to just; Point the builder tool at a part of the base, tap "Q" and then just tap the left mouse button to rebuild the thing you "Q"ed. It will turn up on the screen (one of the top corners, I forget which).

Yup, bulkheads was what made me entirely forget about base integrity. I just built as many as I could and left the vast majority of those doors open anyways. It only require iron and rubber so it is super easy to build and it don't get in your way.

Super easy to find too. Basically just find a Degrassi base with a door and you got it.
