Cost to dig up and re-pour double garage?

For those who ask why, Pyrite is in the 50 year old garage, anyone from Quebec will know what I mean

C'est la PYRITE!!!

There is a whole industry of depyriting houses in qc. Get a few quotes from local companies.

Basement OK?

Basement is almost zero so I'm fine there, only the garage. I have called to setup a few estimates but just hoped someone actually did it.

My garage was done by the previous owners. Many family members also had to have it done.

Cost for a single garage is around 10-12k$. So a double garage might be what... 18-20k$?

There are numerous companies in the area that do that kind of work. They'll be more than happy to come by and give you a quote.

By the way I've seen people dig out the garage and then actually have the new floor reinforced and making a new storage room under the garage.

Just because your IPPG is high does not mean you have to do this. Do you actually have any signs of expansion? After 50 years, it is highly likely your pyrite is fully oxidized and the worst is behind.

Yeah it's definitely bubbled and cracked. You are correct I don't 'have' to do it but it would be nice to have a level garage lol

But if your pyrite is no longer expanding, you don't need to dig out all the back fill just to level the floor.

Has your foundation suffered any stresses?

I would get a proper evaluation by a structural engineer before embarking on major work.
