Polyurethane Foundation Repair
So I’m in TX and was just waiting for foundation to throw me a curveball. Exterior has been done in areas via piers over a decade ago. Now the center of the house is falling. I’ve been proposed a polyurethane fill repair.
Anybody have any experience with this and any insight to its viability? I’ve seen driveways and sidewalks fixed with this method so I know it’s feasible, just not sure on the scope of a project like this.
Edit: I’m also curious as to it’s effect on plumbing in the area. The contractor did say it’s a 20:1 high density foam so I don’t want there to be issues with piping.

I just saw a short video of this yesterday. What keeps the polyurethane from degrading or collapsing back down? It seems like a temporary fix. I could be wrong but that is what I would be concerned about.
That’s my concern, I’ve seen anywhere from 10-12 years upwards to 50. I’ll be perfectly honest with the trouble I’ve had with this house I’m not planning on spending any significant amount of time here.
Why do it at all if you are leaving? Looks like polyurethane was first used about 30 years ago, that isn't a ton of long term data. See some places say underpinning should always be used with polyurethane and others say to use mudjacking. But if you are moving maybe just leave it as is?
It’s not my forever home but I also do still need to live here and minimize issues while I’m in it….
That makes sense if it is actively moving.
