Does the unthinkable

I had a concrete pad that was 22" thick on the sides with stones throughout the pad. A jack hammer and a skid steer hammer attachment barely made a dent. Used a hammer drill with 1 1/2" bit like the directions tell you. With how many rocks were under the pad, a lot of my holes didn't fill up. But the ones that did, broke the concrete and rocks right up. Would use again, highly recommend on thick pads. Less noise then a jack hammer also. 100% worth the buy.
Came fast and packed nice

Came very quickly, can't wait to try it out!!!
*UPDATE* I think it works fantastic, I was digging a 3" deep trench in NH and hit 3 big granite boulders that my little tractor backhoe couldn't even find the edges of. They impinged about 2' into my trench.in height I borrowed a big rock hammer drill from work and found an 1.5" rock drill bit and just using intuition drilled at angles to what I thought would shear the tops off of the rocks, plus holes vertically down to break up the rock as well. Mixed up the Dexpan right where i was working and poured her in. I would go out every few hours and stare at the boulders and of course nothing happened. after 2 days walked out and they were all cracked, Took a crowbar and pried the pieces apart and got them out of the hole no problem. The granite fractured brittle and had a dense "knot" of stone in one spot that it fractured around, so on one of them I had to drill a coupe of more holes and bust that part up, but pretty simple. I drilled and hammered the tops off of some granite in my lawn a couple f years ago to make mowing easier I wish i had this stuff then!

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.
Saved me $1k

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.
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.
