Dexpan Expansive Demolition Grout 11 Lb. Bucket for Rock Breaking, Concrete Cutting, Excavating. Alternative to Demolition Jack Hammer Breaker, Jackhammer, Concrete Saw, Rock Drill (Type 1, 77-104° F)

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.

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.

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

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

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
