Excavator to rip out old concrete?

[Throbbin Rods]

I will be renting an excavator to do some digging around the house and to connect the garage foundation drain to the house foundation drain. Garage floor is terribly heaved and cracked. I am wondering if a smaller excavator will be able to rip out the old concrete given that there are several places to get hold of to start? I have plenty of places to put the old stuff, no problem there. I need the old crete out so I can fill in under the floor where dirt is missing from water intrusion, compact it and pour a new floor.
thanks in advance for any thoughts or suggestions

Depends on the slab and the reinforcing, if any, but pretty much any mini excavator would be of assistance. Worst case would be that you need a demo saw to cut the chunks a little smaller or hack off old reinforcing.

Ayuh,.... The trick will be workin' the hoe under the ceilin', 'n gettin' the concrete chunks small enough to lift out,....

they dripped out my old garage floor with a skid steer.

An excavator with a thumb grapple could probably do it if there is enough space (particularly height) to work.

I agree, a thumb would be the ticket if you have the head room in the bld.

I have just shy of 12 feet headroom. I will likely give it a try while the excavator is there and if it looks to be working I will extend.

Go for it a thumb would be a big help. A dozer blade on the front will help to level things up.

I used a skid steer and concrete breaker to tear up a driveway. I broke it into very small fist size chunks so that it could be buried easily. The larger the pieces you end up with the more likely it will be a problem later.

Do you have any idea how old the concrete is?

Sad that poor construction led to an early death.

 

[Throbbin Rods]

Concrete is 15 years old. Had the garage foundation drain been hooked up to the house foundation drain there likely would be no problem. As it is, the water just puddles under the slab, then when the frost hits it buckles and heaves.

I have 15 acres so lots of room to lose old concrete.
Thanks again for the helpful suggestions

Skid steer with a drop hammer would be my choice. Bust it up, wheel it out.
