The technology does seem interesting. But what's the monetization model?

It looks like it's marketed towards fitting in to the construction process. So I suppose it could monetize as just another construction contractor? But that would mean effectively just a set amount of money per "job," rather than any sort of truly recurring revenue.

It is cool that they don't disturb the surface vegetation or topsoil by simply dumping dredge tailings on the surface. Their method reminds me of injecting expanding foam underneath concrete slabs to lift and level them.

"Flood-prone terrain is then elevated by injecting a wood-based slurry 15–300 feet underground"

This is the part that's odd to me. A wood-based slurry? If there's high organic content in the pump material, won't that decompose (and settle down) over time? I would think that they would want to use something less organic (such as dredge tailings) as their fill material.

They say it's compact within a few hours and doesn't need much time to settle before it's ready to be built on -- but how long does it last?

this sounds like science fiction, it would need to uniformly lift between 18.500 and 370.000 cubic meter of soil/rock by 30cm a day.

300.000 m³ soil/rock would weigh something like 600.000 tonnes and would require ~1.8 GJ to lift by one foot even with zero loss and discounting all other factors apart from lifting the mass.
