Have bought several times. Use according to directions and we break hard blue rock every time. Don't breathe the dust. Be patient for 24-48 hours, as it continues working. One can hear the rock break! Review: Product is great and effective - 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. ## Features - Concrete Demolition and Rock Breaking has never been EASIER! 3 Easy Steps to use: Drill, Mix, Pour. - Amazing 18,000 PSI expansive strength when mixed with water.

How dose it work?** A: I purchased a case of Dexpan last summer to break up a large concrete foundation. It did not work, we ended up hiring an excavator with a large jack hammer. **Q: can we get this product in india?** A: Yes **Q: Would that work on tree stumps? Drill a few holes, put in product and watch the stump break in half?** A: I think it's unlikely that it would work on stumps. Wood is much less brittle and less stiff than rock, so would probably just locally crush around the dexpan instead of splitting. I would call dexpan tech support to confirm. **Q: Which Do I use for a 30 inch thick piece of concrete at 92 degrees f** A: All 3 types work the same regardless of depth. the only difference this product has is the temperature in which you can use it. So based on your core temp. of rock or concrete. If your in the 90's you more than likely will using the Dexpan 1. You always want to apply the product as early as possible. Drill holes and prep day before. If you have any further questions or concerns feel free to call a Dexpan Rep. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Repeated, proven results. *by H***R on January 30, 2026* Does not disappoint.

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. ## Frequently Bought Together - Dexpan Expansive Demolition Grout 44 Lb. Box for Rock Breaking, Concrete Cutting, Excavating.
