Great point. Flow fill would be super slick and cheap. Do you know that they did flow fill? If so, did they punch through and fill from above or fill through the sewer wall before installing the liner or what? I love this system by the way! With a major infrastructure repair needed in this country, this system is an idea who's time has come!
why would this video give gerbils nightmares..

How do you replace washed out cavity above repair? The street will collapse into cavity if it's allowed to remain!

In a situation like this you can pump in flowable fill or slurry.

I believe they cored thru the asphalt and pumped the "slurry" in.
