Frost damage on a one-year-old outdoor concrete staircase

[Stol]

After getting tired of the old poorly constructed concrete stairs up to our house, we hired a company to demolish the old stairs and build a new one. The stairs would have 10 cm high risers (We are older) and the treads would be whatever they turn out to be. Now, a year later, the stairs are starting to suffer from frost damage and I am looking for a product that seals the tread surface and smooths it out. I've googled a bit, but it's incomprehensible and surely propaganda-driven. Anyone knowledgeable in this area, probably belongs in the domain of chemin?

I would probably start by filing a complaint against the company that made it. There are specific concrete qualities for the purpose, which should not freeze and crumble.

I already asked him what responsibility he has: He knows nothing and doesn't want to know anything. So even if I push him, it will only end up badly. No, I want to get someone who knows this and can give advice so I can handle it myself.

Do you have salt on the stairs in winter?

Is it even concrete mix they've used?

nehe står att det skall läggas på golv

Stands for outdoor and indoor, on terraces and balconies, pools and floors in swimming halls.
So suitable for these choices...
No leveling..is a membrane.
