Not sure what it is that your're looking for, but as a result of a recent discussion on augercast piles, I did a search and found

http://www.technicalfoundations.com.

The site had an interesting method of shoring up a roadway constructed over an abandoned mine.

Using pressure grouting and a nylon fabric tube, augering down, inserting the tube and pumping it full of grout. Take a look at the website link to see if this is what you're after.
