Works good
Works really good. Got a bit aggressive with the hole spacing but still cracked the rock all to pieces. Using it on hard granite bedrock in Nova Scotia. It takes time to work properly. Drilled and filled the holes on Thursday and checked Monday, some cracking but not a lot went back the next Sunday, 10 days later and a lot of cracking with many large pieces separated from the main rock.

This product works GREAT!
This stuff works great to rid your yard of those granite slabs. Built a stone wall with all the pieces I removed from my yard. I refer to it as silent explosives. Drill your holes, mix as recommended, fill holes, next morning remove your chunks of stone. My neighbors were in awe.

Great product, but use the CDN website for proper instructions on mixing, etc. for better results
This product worked great for breaking apart a huge Canadian shield rock (a combination of granite and other rock materials) in our basement sized about 4 ft x 24 ft. We initially followed the instructions on the USA website, but it didn't work as fast/well as we'd hoped, so we checked out the CDN site and found out we were mixing it incorrectly. As soon as we started mixing it correctly, before pouring it into the drilled holes, we were seeing initial results before 24 hrs and after 48 hours, the rock was cracked & breaking apart easily. It took my husband a full month & a half after work & weekends to break it almost completely apart. Last pic was from 2 weeks ago, we are farther now. We have just a bit left at the narrow 2 ft part & a bit around the edges. We are happy to almost reclaim a huge amount of square footage in our basement that we will use as a rec room in the near future. Great product, highly recommend.

Worked like a charm!
I’m super happy with the Dexpan product! It worked like a charm. I had this massive granite rock in my basement, and this product handled it perfectly. A big shoutout to Sean from Dexpan for the incredible advice. I reached out to the team with some questions, and he hooked me up with an awesome PDF full of info. Their support was a game changer for my project. I definitely recommend them for anyone who has concrete or rock to break. If I could give more than five stars, I totally would!
