Busting out old concrete... why so difficult?
- Thread starter jeff000

Took him 4 hours and 14 minutes from tracks hitting the ground to his tracks leaving the ground, and he even cleaned it up nicely. We had a ~30'x11' section that really didn't want to break up, he had two helpers cutting wire in the places it was actually in the concrete (most was completely under the concrete).
The shinglers that were supposed to start removal today did a no show, and no one is answering any phones. If all your guys were going to be drunk on sunday morning still don't schedule your guys for sunday morning, Ugh. I even went with a mid price quote cause they seemed the least crack head of the quotes. lol.
We did run into one issue, at the garage we found a 20'x30' sinkhole that was 3' deep, just a huge floating slab over nothing, he was surprised it didn't cave in on itself.
I think the driveway must have slopped towards the garage and water just went between the garage and driveway, but not sure where all the dirt went to???
Talking with the guy doing the new driveway, we are going to pour that area 8" thick, and in front of the garage make a slight culvert dimple to run the water away from the garage doors. There has been issues of heavy rain causing a lot of water to end up in the garage, and just kind of chaulked it up to water hitting the door and then coming on, but thinking it might have been sheeting off the driveway (floor drain to the sewer in the garage makes it hard to tell how much water actually would come into the garage.
The sinkhole is under the footing of the garage for about 10 wide and 18" under the garage. I haven't had the new concrete guy see it yet, but I am a little worried about it, should I be getting them to make an extended footing under the garage? Just tie the garage slab into the new slab with some 18mm dowels? Should I be drilling a couple pile holes in the sink hole? Just fill it with clay and road crush?

There has to be a reason for the sink hole. Is there a drain for storm water or sewer that runs under it ? Before the new concrete is put in, you might want to have a sewer/drain guy come and run a camera through the drains.

I think you really need to investigate the sinkhole and especially if it is running under the foundation. It may be as simple as there used to be a tree there and the roots rotted out, or it may be as bad as an abandoned septic system or drywell. And you DO NOT want a sinkhole under your foundation.

No sewer lines in that area. Nearest is the 15' to the drain in the garage, and then that runs to the house, never getting closer than 15' to the sink hole.
Land was swamp before being residential, I remember catching frogs where the house is now. House footing is on 32 40' piles, No ones remembers if the garage was poured on piles too, and the garage (detached) prints are missing from everything my parents kept when building the house.
The sinkhole part is kinda soft to dig up, like it was a load of not so clay clay in the backfill. The rest of the driveway is pickaxe required to dig it up. I'll get it swept tomorrow and then get them to dig out all the **** soil and fill with packed clay.
The part under the garage is pretty solid. An engineer neighbor suggested to get them to pack it as best they can and then get a mud jack guy to come in and make sure all the voids are filled up under the garage part (since it's near impossible to pack it under the slab.

If you have had the water in the garage problem, your slope is wrong. Regrading so the low spot is away from the garage or a drain grate all the way across with pipe to transport all that water.

I was thinking mud jacking so I'm glad someone else is in that camp. Gravel and stone dust makes a pretty good fill. Maybe you can get some of your concrete back, lol
