Seal box / bag after use. 5) Keep out of reach of children and pets. 6) MSDS (material safety data sheet) is available upon request. 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: Why did I wait so long to try this!!!??? - This stuff is incredible. I was skeptical at first but am very pleased. Tried it on a basketball sized rock in an annoying place on the driveway before I do my big project. Drilled a 4” deep x1 1/8” hole hoping to just blow the cap off the rock so I wouldn’t hit it with the tractor while snowblowing. Came back next day and it was in three chunks! Very pleased. Note that instructions recommend pouring it first thing in the morning, so it has a chance to work during its “critical eight hours“ during the heat of the day. I was too cheap to buy a 1 1/2” bit, got the 1 1/8” for half the price. Seems to be working fine in the limestone I am dealing with. VERY HAPPY with this product. It is allowing me to turn a skidder trail into a road passable by cars and minivans. I have fractured a couple rocks and carefully blown the top 8” slab off others just by changing my techniques. WISH I NEW ABOUT THIS STUFF YEARS AGO!?!?! Why doesn’t Dexpan tell people about their product. BE PATIENT! Results after 48 hrs is always better than 24 ## Features - Concrete Demolition and Rock Breaking has never been EASIER! 3 Easy Steps to use: Drill, Mix, Pour. - Amazing 18,000 PSI expansive strength when mixed with water.

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.
