This sounds a lot like a commercial product you can buy at Home Depot called "Great Stuff." You extrude it under pressure into gaps and holes, and it expands to fill the space... and keeps ON expanding and leaves quite a residue. If that product was amped up through some chemical process, I could see how it could fill part of a tunnel that would take some time to dig out of.
Heh... well SOMETHING like that. More likely, either DARPA or Israel toyed with that product or the binary chemicals that make it up, did a 'gain of function' research on it, and made it into a weapons-grade substance. I'd love to know how that works.

Insulation companies use it on large scale in houses ect.
Yeah, I'd heard of that. Maybe the military has found a way to weaponize it. It's what they do.
Shake up a can and hit from down range...instant tunnel plug.
