We were having trouble getting our garages 3 foot deep foundation broke up. We drilled holes and poured this stuff in and let it do it's magic. This is a great product if you need to break up deep large pieces of concrete. Would definitely 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.

Dexpan used in natural solid Granite Slab to make a ramp ( 10' wide x 6' long and about 45 degree slope). Drilled holes from 24"-32" deep in multiple stages. Spacing of holes were 12"-16" apart. Some of the holes were drilled the recommended 1.5" diameter. Works great. Also tried drilling 1.25" diameter holes. Worked very good for me and sped up the project! I did fill one group of holes with Dexpan while it was raining. Bad idea. Water got into the filled holes and the Dexpan would not expand as designed! Keep area dry if you can and the more time you let the Dexpan " work" the better. Even after 24 hours it was still expanding a little.

After drilling a stone following the directions to the letter placement of the cement and a little time and patience I was extremely satisfied with the results. Practice good safety protocols wear quality eye protection , gloves and skin protection this product works very well.

Product performs as advertised provided you follow the instructions. Drilling 1 1/2” holes in ledgerock is not quick work even with expensive tools designed for the task. It took several days for rock to crack up enough to remove after applying Dexpan to holes. If time is not an issue, it is a cost effective solution.

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 had some giant rocks sticking out of my road and driveway. They were to large to excavate. Following the directions on this product l drilled holes 8 to 12 inches apart approximately 12 inches deep. Once l had approximately 9ft of holes to fill l mixed the Dexpan and poured it into the cleaned out holes. Cracks started to appear within just a few hours. After two days cracks were so large I could easily stick prybar into crack and remove rock as deep as holes that were drilled. Wish l had bought this year's ago. So quick and easy to use and worked better than l could have imagined. Thanks Dexpan! I will be buying more.

I had a concrete pad that was 22” thick on the sides with stones throughout the pad. A jack hammer and a skid steer hammer attachment barely made a dent. Used a hammer drill with 1 1/2” bit like the directions tell you. With how many rocks were under the pad, a lot of my holes didn’t fill up. But the ones that did, broke the concrete and rocks right up. Would use again, highly recommend on thick pads. Less noise then a jack hammer also. 100% worth the buy.

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.

Worked extremely well!! I had a hard time finding reviews with only partially exposed rock. My rock doesn’t seem to have a bottom to it but I only needed to remove the top 12” at the rocks highest elevation. I used 1 1/4” bit and also a 1” bit. The larger holes produced larger cracks. The larger bit does take longer to drill. I would if I used a 3/4” bit first then the 1 1/4” after that seems to make the process go faster. Tried enlarging the 1” holes with the 1 1/4” bit and the larger bit kept getting stuck. There is a learning curve with drilling, you will need a pipe wrench to unstick your bits. Bought a roto hammer drill at HF for $125; that would have been a 2 day rental at HD.

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

Had a big granite boulder to break in the basement. Dynamite was not an option indoors. After some research, found out about Dexpan. I was a bit skeptical at first but decided to give it a try. Did not had the needed equipment to drill 1 1/2 inch holes as recommended. Made 7/8 holes instead but made them closer (about 8 inch). Took about 2 days to have the first crack. After 4-5 days, the boulder was cracked all over. Dexpan made a very complicated and expensive job much easier and, most of all, much cheaper to accomplish compared to breaking the thing with rental jackhammers and such. Recommended!
