How to break stones, rocks using Dexpan type 3
Depending on the weather, and the temperature of the stone/rock the expansion, usually, takes about 24 hours. Sometimes, it takes more than 48 hours to see the substantial crack.
The technique that I developed for myself is the following; I usually make the first hole using a 5/8 of an inch drill bit. And then I enlarge this hole by the 3/4 inch, in the video, you can see that the first hole goes much slower than the following one. This way it's much easier for Bosch to drill a smaller hole and then to enlarge it with 3/4. Plus 5/8 inch is also much chipper than 3/4 and I while I drill holes, I change drill bits often, allowing them to cool.
Materials and instruments used
Set of 2 paint, mud, and cement mixer blades - amzn.to/3NeoEt2
BOSCH GBH2-28L 1-1/8" SDS-plus Bulldog Xtreme Max Rotary Hammer - amzn.to/3x2nl9P
Dexpan Expansive Demolition Grout 11 Lb Type 3 - amzn.to/3GDvR3z
Dexpan Expansive Demolition Grout 44 Lb. Type 3 - amzn.to/3GES01g

I bought 6 drills of 5/8 inch diameter and 3 drills of 3/4 inch. And after breaking quite a few rocks, still using all of them.

Good job, I'm surprised that you got such a good result with such small hole diameter.

@timhofstetter5654 Год назад

It already had a big starter crack. Why didn't you start there?

@NJAsmodeus1 Год назад

All I could think about as the video started was “nice place to start the project right there.” If it wasn’t a time sensitive project and was in a zone that regularly freezes in winter, I would have just worked with water and makeshift wedges to make that crack do the work for me

Glad I'm not the only one taking on what seems like an impossible task. Mind blowing how well this stuff works. Where in MA are you I grew up there and live in southern NH

There are types of this material. What is the difference between red, green and blue?

@todivetoday 10 месяцев назад

thank you. Sorry for getting back so late. But I never got any notifications about left comments. It is most likely my mistake, I'll check why I do not get 'em. Cheers My understanding, the difference between the three types of materials is the outside temperatures that aforementioned material can be applied. some can be used when it's very hot outside, and some when it's colder. Cheers

My SDS plus Bosch Makita drill bit keep on breaking even if I pour water , can I use pointed chisel bit to make hole ?

@todivetoday 10 месяцев назад

I would not pour water on a hot tip. My technique to minimize the heat of the tip and prolong its service life - is to change bits often. I do not push too hard, when I drill, giving a chance to a drill to do its work. A minute later I remove the drill, place it on the rock, and in the meantime, I insert the second drill. A minute later, I repeat the process and inserted a third drill. Then I return to the first one and so on. I would not recommend using water on a hot drill bit tip. Cheers

That looks like a Bosch rotary hammer drill. What model? What was the rock type- basalt - granite. If it was either of those two it was amazing. I am trying to drill granite with a Chinese rotary hammer drill and start with a small 3/16" drill working my way up to 5/8" for inserting wedges and feathers. However I keep ending up with mushroom tips on my drill bits as they melt in the rock.

@sylviam6535 Год назад

You need to keep the drill tip cool by drizzling water in.

The unit I used is BOSCH GBH2-28L 1-1/8" SDS-plus Variable-speed Bulldog Xtreme Max Rotary Hammer. I do not know what time of a rock I worked with, but I think it is a granite.
