So i was just looking for a simple deilling hammer... all a sudden i see this stuff and wonder, how have i lived without this!? How dose it work?

I purchased a case of Dexpan last summer to break up a large concrete foundation. It did not work, we ended up hiring an excavator with a large jack hammer.

Would that work on tree stumps? Drill a few holes, put in product and watch the stump break in half?

I think it's unlikely that it would work on stumps. Wood is much less brittle and less stiff than rock, so would probably just locally crush around the dexpan instead of splitting. I would call dexpan tech support to confirm.

Which Do I use for a 30 inch thick piece of concrete at 92 degrees f

All 3 types work the same regardless of depth. the only difference this product has is the temperature in which you can use it. So based on your core temp. of rock or concrete. If your in the 90's you more than likely will using the Dexpan 1. You always want to apply the product as early as possible. Drill holes and prep day before. If you have any further questions or concerns feel free to call a Dexpan Rep.
