Review: It definitely works!!! - Works Amazing. Be sure to order the right temperature for your location. The shadows of trees will slow down the process. Still worked great but took a bit longer to crack. Real easy to use, be ready you have to work quickly. Starts to thicken up quick. We used it for ledge pokers in the grass. Worked on granite. Over all does what it’s supposed to do. Definitely recommend.
Review: Very effective for breaking rock - A safe and effective way to break up rock. I had a troublesome piece of shale in my driveway. I was unable to use heavy equipment to remove it due to a buried cable nearby. I drilled a series of 1-inch holes, ten inches deep on an eight-inch grid (about 30 holes total) then filled with the Dexpan slurry. In 12 hours, the rock was completely shattered and easily removed by hand. I was able to use a funnel to fill the holes as the mixed product is about the consistency of pancake mix.

## Questions & Answers

**Q: What type of drill is best?  i used my bosch 8.5 amp hammer drill with a 1” bit.   it lasted 10 minutes and shut down.**
A: I used a rather large hilti drill for mine with a 1.5" bit and even that thing was very hot to the touch after two 16" deep holes. I would do a few then let it cool. I'd say that drill is a good drill for most things but not for a 1" drill that's over 9" long.

**Q: Can you drill smaller than 1.5 inch holes in the concrete? I have a 1 inch drill bit - hence the question.**
A: You can use smaller holes, many clients including our own staff have had much success both with smaller and larger holes, however, the holes need to be closer together, no more than 6" apart and you must allow more time, we cannot guarantee the timing or results if you use anything smaller or bigger. Thank you for the great question!

**Q: I have a boulder 8' wide by 5 ' tall , will this work on it? And how far apart should i drill the wholes**
A: Wow that’s a big rock, mine was 1 1/2 feet tall and 3ft wide. I drilled 1” diameter holes 1 ft deep and 6-8” apart and it worked great over night. It says not to drill all the way through and about 1ft apart in a grid pattern. Good luck.

**Q: Can I just pour it into cracks of the big rocks and not drill holes**
A: I think it would work fine, efficiency would depend on depth and width of the crack versus the size of the rock. You'll need to dam the crack to contain it in the area you want to expand in. It is very runny when mixed and you do need to follow mixing and safety instructions. After the reaction takes place ( a day or so ), the stuff is as inert as limestone so no hazard that I am aware of. The primary ingredient is Slacked Lime & the Romans used it in cracks to break rocks for building roads so the history is extensive. I have some photos of concrete breaking that I did with it and I wish I could share them.  Try mail to toymkr at a o l dot c

### ⭐⭐⭐⭐⭐ Great Stuff !!!
*by C***E on June 8, 2016*

The Product really does work. I live in Northern Maine and we have a lot of huge garnet rock. I needed to remove this rock so as not to hit it while plowing snow in the winter time. I had a friend with an a Large Linkbelt Excavator try to move it, the Excavator could not even budge it, the machine stood up on its side, with rock not even budging. So then someone told me of this product and though I would give it a try, for the price, its worth a try. Not really believing that it would, so I proceeded to do as the instructions read, however, I only had a 1" drill bit and drilled the proper amount of holes as needed. Mixed and poured into the holes and walked away for 48 hours and its doing the job. Many people are asking does it really work, I have taken pictures of the cracking so as to show them, and of course the rock missing is also a testimony to the produce.
