Warm spot in garage floor?

Greg,

David Valley may not be too far off...... Possibly you have a uranium (or other radioactive material) deposite under the slab. Have a Radon test conducted as the gas can migrate through concrete. Gods Speed and good luck.

probably a piece of insulation left in the slab when poured and retains heat in that area?

I wouldnt dig before safe dig called maybe an old line

It's the garage floor version of Pandora's box. If you jackhammer, have on hand a priest, medicine man, houngan, warlock and a fast horse saddled and ready to ride. -Kent

I understand when meat decays it generates heat. Do you really want to know what is down there ? I wonder?

Greg- get a hammer drill with a 3/4" bit and drill that puppy... don't keep us in suspense any longer.
Go slow. If there's a fluid leak (hot water pipe) it will have wicked into the concrete slab by capillary action by now. You should hit wet concrete before you hit the pipe. A void wouldn't be hot.
Paul's got a point. can you feel the difference with your hand?
Bacterial action can generate heat but I would expect it to be spread over a wider area than just a spot.

Alright, I give up.
If we are going to persue this Mystery, let's try this;

1. Drill a small 3/16" hole with a hammer drill at the suspected hot spot.
2. Make sure you have a piece of lead solder in hand or near by.
3. Take a temperature probe gauge and check the temperature of the probe hole. If it reads more the the ambient air temperature you have a problem.
4. Make sure you have a small blow torch in case you need to resort to step 2.
5. Cut a piece of coat hanger, staighten it out and stick in the hole and see how deep you can penatrate without resistance.
6. If a void is present, you have a problem.
7. At this point, do not light a match.
8. Insert a syrinch and inject one gallon of water. If it bubbles out, and starts foaming, uses step #2 and #4.
9. Go to the Deeds Office and make sure you are clear on the title of this property.
10. Contact your nearest Oil &Natural Gas Investigation Office.

I'd recommend a full geologic anallysis before you drill. Possible magma chamber under the house with a lava tube peaking under that spot. Try contacting your local universities Geophysics department to find out for sure. While you're at it, learn the old song "On top of old Smokey"... It may come in handy when the volcano erupts in your back yard.
