Disaster film involving expanding foam?

0

I remember a film from when I was a kid playing on TV.

I do not remember much – all I remember is it was one of those awful disaster films – the ground started falling in underneath people, and later they found out the ground underneath the city is hollow in some places and the ground holding them up isn’t strong enough.

At the end, they find a solution to use ‘expanding foam’ on a LARGE scale and fill the ‘hollow’ underground bits?

I promise I’m not making this up 😭
