Amazing stuff. Around 2009 - 2010 the world famous HundertwasserToilets in Kawakawa were under threat from erosion by the river at the back of the building. I rang the council when I heard about this and I was the 3rd or4th person to call regarding the use of expanding foam to stabilize the embankment and realign the building, I was able to give the guy I spoke to a contact number for a local business,(been on the piss with them a week before).
One thing I will say about Far North councils is that the majority of people they employ are switched on,(not the yea sayers just the actual doers),and after brief public consultation and a fundraising campaign the building was reinstated and future proofed.
Every time I stop for a piss I feel pleased that modern technology if used wisely is a wonderful thing.

In comparison, worked for an immense [nearly 200k employees] multi-national corporation. Their restrooms were famous too, largest cockroaches imaginable. Having plant built atop a horse racing track might have something to do with it.

Worth saving. What a piece of work they are indeed!

Locals are very proud of their loos. No graffiti, no vandalism, clean, functional, useful and everyone walks out smiling. Real happy place.

That stuff's crazy. It's like 5000 - 6000 psf or something.

Where did you find this? I can't find any technical data.

A structural engineer told me that years ago. I'm just regurgitating what he was saying when he was praising the stuff. But based on what I found below it looks like there are a number of structural foam products that far exceed that number.

Here's the datasheet for (rigid, non-expanding) Corning Foamular boards. They make Foamular 400, 600 and 1000. That corresponds to 40 psi (5760 psf), 60 psi (8640 psf) and 100 psi (14400 psf). They recommend it for under concrete foundations, roadways, airport runways and railbeds.

Here's an expanding foam product called Polylevel. The manufacturer says it's good for almost 6000 psf.

This website says their under-foundation polyurethane expanding foam product is good for 7200 psf, but that website is suspect to me so take it with a grain of salt.

Here's another one called GeoLift, and it comes in two densities GeoLift 4.0 and GeoLift 6.0. The 4.0 is good for 58 psi (8352 psf) and the 6.0 for 110 psi (15840 psf).

Ok Much less than Concrete. Concrete is 300PSI for non air entrained concrete.
