Expanding foam to level a sidewalk.

[twarren]

I'm wondering if anyone here has had personal experience with this concept to lift sections of sidewalk.
Availability of product, cost and life expectancy would be my main concerns.

I saw a video on YouTube a few weeks back.
Obviously promotional and seems like a decent idea, but it gave no indication as to any down sides...

We use a company at work to level roads and parking lots with expanding foam. It’s not something that can be a DYI as it has to be injected with a bit of pressure and done through multiple holes a once to get an even lift.

Yeah, that sounds like the method I saw on YouTube.

Had quotes last year to raise 250 sq. ft about 2-2 1/2" and most came in at about $1200 with guarantees of no further sinking of the slabs.Friend does concrete and said he can't touch that price to do a tear out and replace along with him tearing up the back yard too.

Thanks Flat350, I hadn't got as far as having any ideas of price to do this. Interesting to note that there was actually a guarantee against future sagging. I don't know if such a business exists in my area or not. I will have to do some research.

Can you ask your buddy if he knows of anyone in central Texas. I was just about to look into this to level out a 10x10 patio at our new to us house that over the years is now sloping towards the house foundation instead of away from it. Gutters and leveling the pad will hopefully help my french doors from going out of plumb when we get a good rain. Got to love black dirt.

Lifting a sidewalk plank? I ran across this video on youtube a while back. Looks simple enough with basic tools.
