Expansive Demolition Grout 44 Lb. Bucket for Rock Breaking, Concrete Cutting, Excavating. Alternative to Demolition Jack Hammer Breaker, Jackhammer, Concrete Saw, Rock Drill (DEXPAN44BKT2) (50F

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.

Awesome product, had a rock the size of a small junky car (fiat) that was in the way of a planned addition, knowing an excavator with a hammer would be at least $5k to mob in chip for a day then mob out i searched the memory banks and remembered a Maine home show had a similar situation to deal with and used a product that expanded, online and Amazon search brought me to Dexpan, most of the videos cover thin concrete slabs and rocks, my rock was about 4’ thick and 10’ long and irregular shaped, i drilled enough holes for one bag 1-1/2” by 14” at 12” centers, mixed up the bag and dumped it in, it took around 18 hours to fracture, peel the rock off with a digging bar and drill in the next round, i went through 2 buckets so 88 pounds, each hole took about 20 minutes to drill so the project took several weekends but the rock pieces were small enough for a mini 50 to move around so when my digger showed up to excavate the footings he could perform his work, so $300 versus $5,000+, would and likely will purchase again

I wanted to crack this large rock to make a bench. Drilled 12 holes, 2 feet deep, with a 3/4 bit. Very horizontal. I can normally fill 20 or so holes with one bag. I wanted to be there when it cracked so I drilled 10 more holes in between the holes and put in 10 wedges. And after less than 12 hours got a nice beautiful flat crack. Since then, it's continued to lift the rock.

This stuff works great. You must read, understand and follow directions carefully.

the product worked pretty well for removing concrete stairs. Broke off in pieces that were manageable to haul away. The only drawback to the product is very few people will have the needed sds max rotary hammer drill or the 1 1/2 inch diameter sds max drill bit needed to drill the recommended hole size. I bought the drill at harbor freight for $179.00 and the Bosch SDS max bit at Lowes for $109.00. You have to drill quite a few holes at the recommended spacing of 12 inches apart if you want the concrete to break off in pieces that can be easily lifted and hauled away. It took me a couple of hours to drill the holes but the payoff was being able to walk away and come back the next morning to remove the pieces that had cracked between the holes.

This stuff is amazing. Wish I knew about this sooner.

Works great!!!! Saved on equipment rental!

This is an amazing product.

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.

Product to use to split off the front edge of a cement porch.

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.

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!

Should have bought this years ago. Much faster/easier than a jackhammer.
