I break big rock at home. This produce (10-25°Celcius) work 3 years after purchase if keep in a dry place. I get 4 bags of 11 lb (so they are well seal).

Dexpan Expansive Demolition Grout gets the job done. We used it for 2 different applications and it really impressed us on its performance both times.The main reason we were using the Dexpan was to demolish a small concrete pad in a location where it would be difficult to use large tools. The holes were drilled per instructions and the grout was mixed per instructions. After mixing it has a soup like consistency. After pouring the grout into the holes, we left it for about 16 hours before checking on it. The pad was completely demolished and the concrete floor beneath the pad was left undamaged. Clean-up was just as easy as using the product.For the second application, we used it to break a large boulder on a hillside that needed to be removed. The same process was done as we did in the first application and the next morning, the boulder was broken up into pieces small enough to carry by hand.Overall, it is a great product that works very well. The main benefit being that it saves time and money by eliminating the need to use heavy equipment and tools. It is very simple to use and is very effective following the instructions for use. The only thing of concern is that it has a very high PH making it a dangerous substance to use and can be harmful if it get on the skin. However using proper personal protective gear such as rubber gloves and safety glasses mitigates the risk. It also washed off the skin with soap and water.I highly recommend this product for its intended use. It is easy to use, effective, and save time and money.

Five foot wide rock unearthed during excavation drilled four holes with a 1-1/8" x 33" long bit. Poured holes full of dexpan according to instructions. I let it sit over night because it was cool and wet weather, by the next morning one rock became four pieces. It honestly outperformed my expectations and I'm going to keep some on hand for future needs.

We have done multiple projects with this product breaking granite rock outcrops. One area was 50' long x 15' wide and up to 5' deep. It did require a pallet of product and some serious pneumatic drilling but result was excellent.With care and by following instructions you can also be quite precise with what is cracked out and what is left intact. We have carved off over 8' deep rock edges in straight lines. There are some good guides for drilling patterns available for this and similar trade name products online.

The simplicity is amazing but you need more than you think if you go with 1.5" holes, dexpan 3 is tool of choice at the time of review for cold weather breaking .P.S. make sure your drill is on low speed!

This product works very well but you must pay attention to the directions.The larger diameter hole works best and be sure to clean the hole as best as possible and do not drill all the way through the material. Also be sure to work at the range of the material temperature and realize the ground temp is most likely 10 degrees colder than ambient.

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 is from 2 weeks ago, we are further 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 putting on an addition to our house. When digging the hole for the foundation, we hit ledge about 6 feet down. This would have severely limited our basement ceiling height. The ledge consisted of a mix of gray NH granite and some insanely hard black rock. I had to take off about 1.5 feet of ledge to get to a 7 foot basement ceiling. We will end up owing the excavator about $1000 in machine time for beating on it with the hammer he has on his skid steer. A larger machine was not available. For that machine time, we took out the two highest peaks, but the vast majority of it remained. So I gained about 1/2 foot this way. The excavator did not have any good solutions for me. I went on the web and found Dexpan. Watched a few youtube videos and convinced myself that I had a shot at this. The excavator and foundation guys were both very skeptical, but hey, when you're desperate, you'll try anything. The first day I drilled 30 holes as a test. The next day I saw a few cracks appearing. I ended up drilling about 120 3/4" holes 10 inches deep each. Holes were drilled about 6 inches apart, and were carefully chosen to take advantage of existing fracture lines in the ledge. Took about 8-10 hours of drilling time. The Dexpan succeeded with cracking up the ledge to the extent that the excavator could come back with his skid steer hammer and bust it all out in about an hour. I got an additional 1 foot of ceiling height out of this and now we are finally ready to pour the foundation. DEXPAN ROCKS!!!!! Forgive the pun. By the way, I think I would have been better to have ordered lower temp range Dexpan. Some of my cracks took a couple days to even start. I think with the lower temp product, it would have gone faster.

I needed to remove some granite ledge near my garage, and I highty recommend this stuff after having used it!I drilled eleven 1.5" holes in the granite ledge, but only filled 10 with Dexpan for the first round (used 1 bag). My holes were at 58 degrees when I started filling (8am) and the daytime temps were in the low 80s. I used the #2 Dexpan (55-77 degrees). I mixed with refrigerated water too. The holes near base/gravel were about 7-8" deep and at about a 45 degree angle. The upper holes were 12-13" deep and vertical. All the holes were about about 12-14" apart. I started with an upper hole that had the steepest face near it, figuring it could crack/expand the easiest, and then I made a clockwise pattern from there. I had a couple of slight cracks at the 10 hour mark (none at the 8hr mark). By the next morning I had more cracks and wider cracks. I gave it a 72 hours to make sure it did all the work, and it started to mushroom up about 48 hours in, most likely from the lower holes that were on an angle as planned. The end result was some big chunks of rock on the outside (but easily liftable), the middle layer was obliterated (3-5" pieces/slivers and smaller), and then some much larger (to heavy for me to lift) pieces down deeper. There are more cracks still, but I have removed most of what I wanted to remove. I'm impressed and pleased.
