Works great. but their temperature recommendations seem off a little.

I wanted to tear down a wide concrete wall.
The wall had a core temperate of 52 degrees so I bought Dexpan 2 (for 50-77 degrees).
Drilling 1.5" holes put cracks in the concrete but didn't split it.
I then bought some Dexpan 1 (for 23-50 F) and drilled 1.5" holes every 9".
Next morning, the wall was all but demolished.
Dexpan's support was great! They even sent me some extra Dexpan to replace my first batch.
I'd recommend talking to Dexpan's support before you begin and getting a small batch to test.

I dug footing for my cabin and hit two major granite rocks. I purchased a $700 dollar jack hammer and it didn't even make a dent. Backhoe with rock hammer would have been $1,700 a day. I bought a Bauer hammer drill ( get SDS max), landscape lever, and a small paint mixer for around $300. This product has absolutely impressed me. Just don't take short cuts. Drill deep and buy two bits. 1" works great. I wish I would have found this years ago when I built my house.
Help my husband great deal

Worked great on giant granite rocks in my driveway.

These were very large granite boulders that the excavating company couldn't remove during final grading on part of my driveway. Parts of them were 18-24 inches thick. Boring with the proper hammer drill was pretty easy; renting one with an 18" drill bit was about $125 for the weekend. Make sure you calculate the right amount to buy. An 11-lb bag fills about 9 linear feet of 1-1/2" bore holes. Also choose the right temperature for the product and remember that ground temperature is a lot lower than air temperature. I actually had an infrared spot thermometer that I pointed down into the holes to make sure I had the right range, as we'd already had a number of hard frosts. Pictures show the cracks in one boulder. The other photo shows the pile of rock chunks that I subsequently removed, using a landscape bar.
you need a SDS Max rotary hammer drill. An SDS Plus rotary hammer will not hold needed bit size.

the product worked pretty well for removing concrete stairs. Broke off in pieces that were manageable to haul away. The only drawback to the product is very few people will have the needed sds max rotary hammer drill or the 1 1/2 inch diameter sds max drill bit needed to drill the recommended hole size. I bought the drill at harbor freight for $179.00 and the Bosch SDS max bit at Lowes for $109.00. You have to drill quite a few holes at the recommended spacing of 12 inches apart if you want the concrete to break off in pieces that can be easily lifted and hauled away. It took me a couple of hours to drill the holes but the payoff was being able to walk away and come back the next morning to remove the pieces that had cracked between the holes.
