Review: Breaking Boulders - Used successfully to break up some large boulders in the garden. Did require some hard work to drill the holes to accept the grout but got there in the end.
Review: Great product!! Impressed!! - Really impressed with the product considered I was skeptical. I had a fairly large granite Rock that I have been wanting to get rid of for years but it was much to heavy to move. Tried drilling holes in it, used a concrete saw to cut into it .. for the life of me I could not break it down into smaller pieceS due to its size. This product did what I couldn’t do within 24hrs. A little pricy but considering it resolve a long due problem for me worth every penny. Amazing and thank you for the great product. I showed my parents and friends and my dad has already purchased and used it on some large rocks at the cottage he wanted gone. Works there as well. MAKE sure to follow instructions exactly as described. In my cases I divided the volume into 3 so I gave myself 3 attempts to achieve what I needed since I had more than I needed for my rocks. It did the jump 1st time around... used a second batch to break down the rock even more... all I can saw is amazing :)

## 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
