    Just got done replacing 50tons of soil with 3/4 clean stone. started a small raised patio on friday and we excavated to what we though was a sutibale base. then we started running the compactor on it just started pumping the water and moving like jello. so we started excavating a little further and what do you know, we found 2' of garbage soil the contractor brought the grade up with on the site. i thought we would never find the bottom of it. this had to be the biggest over dig stabilization we ever did. it looked like we where installing a swimming pool, not a patio. could not have done it with out our new 277B though, it was awesome climbing in and out of the hole with all of that muck. luckily the neighbor wanted all of the fill we dug out. wish i had taken pics, but was to stressed about getting it done and over with to stop and get the camera out.

    Gotta love it! My new construction story involves demoing a concrete front stoop and then installing 14 courses of 12 inch block since you need to go all the way down to basement footings to get to stable ground.

    I have another front i am doing that should be a over dig situation. BUT since i have concrete footing already there i am just pouring a slab with a TON of rebar and mortaring my techo quarry stone right to the slab.

    We're about to step into the same pile of s**t, we're doing about 500 square ft of techo walls in a yard that has just been rough graded, I was there the other day while they graded it off, we will have to dig min. 7 ft in spots, they GC had the gravel installed for the driveway, and we will have to tear it all out for the geo-grid requirements of the wall. Oh well lots and lots of extra machine time.

    I can only imaging what would happen if a hack got one of these jobs.

    I think we all know how that would go.............

    I wish they would pick up the f***** nails so i dont get them in my loader tires. My peaves are the rough grades where the have the water running in to house instead of away. The other one is around the a/c or heat pump unit on the side of the house, garbage dirt up to base. How do i add my 4-5" of top soil.

    Matt - Why the hell would you do that? Install as an overdig stabilization, wrap per the detail, install 6" of compacted aggregate, install one burried block per specs. or, you love to throw tons of money away.

    Overdig or no overdig, I'm having a better feeling of drilling some 1/2" holes into the foundation every two feet and inserting some rebar. The rebar can protrude out into the overdig and help prevent further settling by locking into the foundation. I bet in the near future, a concrete footing will be required as the zoning laws keep being modified.

    Are you actually for real about drilling holes into the foundation?

    Which job you talking about? The one stoop is full masonry and builsing inspector made us go down to the basement footings.

    The other job is a techo bloc stoop. But i'd have to do a 8 ft over dig to hit virgin soil. Pourin a slab over the existing stoop footings will save me time and $.
