"Goodness! They must be wildly expensive!"

No not too expensive and they can be fund used an any heavy truck scrap
yard.  With care they can be used as very effect "air cylinders."
Just remember that pneumatics goes "slam bam thank you m**"

Don't sweat the tack effect on semi air suspension bags, they're designed to
support oh say 40,000 lbs. in sub zero temps and take seriously bad roads
like say the Pipeline haul road (Dalton highway) Besides being more than
able to take the load hammering them, they're up to surviving serious road
hazards, often about the only salvageable part of a wreck are the air bags.
Heck, you can't shoot a hole in one with any pistol I know of.

that hard . . . Nevermind. To control the boinky nature of spring mounted
machinery do what the pros do and include some shocks. Heck, you could have
the only air ride hammer on the left coast.

>>> Jerry, we are on the tumbled, wrinkled scrapings resulting from tectonic
plate subduction. Under us we have 2 kinds of sandstone, chert, pillow lava,
prehistoric beaches, clay layers and who knows what all. Because it's so
steep, the little creek has cut deeply and the  scaling ravine walls  are
pretty darn vertical as it nears the ocean. Coming up off the beach, the
first 100' or so is also vertical, heavily fractured rock. Roughly the angle
of repose sloping up the mtn to us. I don't see any real possibility of
stabilizing structures and figure that at the age of 68 there's no point in
even trying.

dump trucks and tour busses rumbling by every day. The hammer site is a fair
distance from the most unstable faces.

pure BS driven by an AH bounder with bureaucratic ambitions) and the new

fiasco will prove expensive in the long run.

I've driven 1 a few times since moving to AK, maybe 4 times but I've never
put boots on the ground there. Close maybe but probably not within many
miles.

probably be a useful test. No! Don't do water packers!

would be more important than any foundation or slope stabilization design I
could suggest, even with a good subsoil report in hand. And YEAH, I still
have friends I can consult. I don't know if any of the Caltrans guys would
remember me but there is one guy in FHWA who would if he hasn't retired.
