Yes, you can convert a crawl space into a slab on grade foundation, it just isn’t a particularly cheap process. You would need to jack the building up, and depending on the situation either remove the existing foundation or fill it in, then pour a slab on grade and rest the house back down on it. We of course can’t give you any specific advice on how to carry it out, you would be best to consult a local engineer or general contractor for that. If you have a high water table I would suggest a raft slab that has no footing and spreads the weight evenly over the whole surface, so you don’t need to dig as deep. That way you can avoid any issues with drainage while trying to build the footing.
If that turns out to be too costly, remember that you can repair crawlspaces in most cases, see here for more info on that option, as well as how to mitigate radon gas –
