## Description

Product description Dexpan Non-Explosive Demolition Agent for Rock Breaking, Concrete Demolition Removal and Stone Quarrying Alternative to Blasting, Demolition Jack Hammer Breaker, Jackhammer, Diamond Blade Concrete Saw, Rock Drill, Concrete Breaker, Rock Breaker Are you the DIY home users trying to break huge rocks? Jackhammer won't work? Are you the contractors trying to demolish mass reinforced concrete? Try to prevent damage to heavy equipment? Are you the quarry owners trying to avoid waste of valuable stone and increase stone quarrying production and safety? Concrete demolition removal, rock breaking and stone quarrying has never been easier with Dexpan Non-Explosive Demolition Agent. Dexpan is a cement with amazing 18,000 psi expansive strength when mixed with water. Poured into pre-drilled holes, Dexpan can break concrete and rocks safely and quietly, while providing silent cracking. It is safe, easy and cost effective. AKA Dexpan Expansive Demolition Grout, Rock Splitting Compound Chemical. Benefits 3 easy steps to use: drill, mix and pour. Controlled demolition and easy clean up. Silent cracking, breaks concrete and rock without noise, vibration or dust Concrete removal, rock breaking and stone quarrying has never been easier with Dexpan Non-Explosive Demolition Agent Controlled Concrete Demolition is as easy as Drill, Mix and Pour! Dexpan cracks according to drilling patterns. Demolition contractors, drilling and blasting contractors can easily break reinforced concrete or rocks into desired sizes and shapes, so they may cut off exposed rebars, haul demolished chunks away with a crane or excavator without damaging the desired remaining parts. Rock breaking and concrete demolition have never been easier and more effective. Dexpan is capable of demolishing multi-ton weight reinforced concrete structures and rock. No Noise! No Vibration! Silent Rock Breaking, Removal and Excavating Dexpan Non-Explosive controlled Demolition Agent can also be applied along with traditional demolition tools like jackhammers, wrecking balls, hydraulic breakers, diamond blade concrete saws, diamond wire sawing machines to help cut cost, work time and increase safety. Plus because it works as silent cracking, Dexpan is perfect for demolition contractors, drilling and blasting contractors who work in residential, schools, hospitals, airports, and other noise, ground vibration, air blast, dust restricted areas. Dimensional Stone Quarrying, Avoid waste of valuable stone! Increases Stone Production! In Mining and Stone Quarrying industry, Dexpan helps to acquire perfect slabs and blocks from limestone, onyx, marble, granite, sandstone, flagstone or many other types of natural stones. Compared to explosives blasting and detonating cord, Dexpan non-explosive demolition agent avoids waste of valuable stone, high cost of blasting insurance, storage and labor. Not to mention increased safety and stone production. Compared to diamond wire sawing machines, Dexpan avoids high cost of equipment, replacing diamond wire, complicated setup, relocation and maintenance, there is no limited cutting distance due to length of diamond wire, no cooling water and high voltage power supplies required. Standard Drilling Pattern This Drilling Pattern uses Dexpan to its fullest to crack your concrete or rocks into easily removed sections. Space each hole 1-Foot apart from the others, measuring from the center of each hole. Make sure at least one side of the project has free space to expand to equal to the depth of the holes. Minimal Dexpan Use Drilling Pattern This Drilling Pattern is designed to use the smallest amount of Dexpan to cleanly split rocks and concrete into sections. Buried Rock Drilling Pattern By drilling diagonal holes into the surface of a buried rock, Dexpan can work to push the rock upwards, cracking it into the free space above the rock. Dexpan Hole Size Comparisons When using Dexpan, we recommend drilling 1.5-Inch Holes to make the most efficient use of the project. Smaller holes do not contain enough Dexpan to adequately provide force against the rock, and larger holes cause Dexpan to cover a smaller area with the same amount of product. Frequently Asked Questions How much concrete can I demolish with a box of Dexpan? A standard 44lb. box will cover approximately 35 lineal feet of drilled holes, which can be used in a standard pattern to remove 60 cubic feet, or 1.7 cubic meters, of concrete. A 11lb. bucket will cover approximately 9 lineal feet, or ~16 cubic feet (.45 cubic meters). Dexpan is recommended for projects with a depth of at least 8 inches. Which Dexpan should I use? Use the ambient temperature of the area surrounding the rock and compare it to the temperatures listed on each type of Dexpan. A local weather forecast should be enough to determine the appropriate type of Dexpan. For Temperatures between 77-104° F (25-40° C), use Dexpan #1. From 50-77° F (10-25° C), use #2. And for 23-50° F (5-10° C), use #3. When should I pour Dexpan? The best time to pour Dexpan is the morning after you drill the holes, immediately after combining the product with water. Doing this as early as possible will allow Dexpan to work throughout the day. Dexpan pushed itself out of its hole! What went wrong? We refer to Dexpan pushing itself out of the drilled hole as a 'blowout', and it can occur for a few reasons. The most common is when the project does not have adequate expansion space. Be sure that there is an empty area next to the rock at least as long as the depth of the drilled holes so that Dexpan has somewhere to push the rock. Blowouts may also occur due to high temperatures (especially when using the wrong Type of Dexpan), large hole diameters, and using Core Bits to drill holes.

Review: Patience pays off! - I bought this product and was questionable about how effective it would be. I used it on a 30"x 60" concrete step that had been in place for approximately 54 years (no rebar). The videos I saw of how to use the product indicated you would see cracks appear anywhere from 4 to 6 hours. However, none appeared and when I looked out the next morning nineteen hours later there was still no signs of any expansion. Checking 4 hours later at the 24 hour mark as the directions indicate, still no cracks. I was very disappointed and tried to drag the block with my Kabota to no avail as it was just too large. I ventured out 7 hours later to see what my wife and her sister were up to and they indicated that indeed the steps had cracked in half. Bottom line, be patient. If you follow the directions with an eye on the temperature and I was right on the borderline of it being too cold, also the depth of my holes were a little short of what the directions call for....the product works wonderfully. I would highly recommend it. Always wear a dust mask as the powder is very fine and blows easily in the wind. Be sure to use the correct amount of water and clean up is also a breeze. I completed four holes approximately 18 inches deep and could have completed perhaps two more as a guess so make sure you have sufficient product for your job.
Review: Dexpan is a Game Changer! Way better than SDS-Max Demolition Hammers! - This product is incredible and a must-try! Dexpan demolished 6,000 psi CTS RapidSet 24/6 concrete with ease. The instructions recommend using 1 1/2" holes, but I achieved these results with 1-1/4" and 1" holes. Despite my shortcuts, Dexpan delivered outstanding results! I'm a huge fan of Makita, but their demolition hammers—specifically the Makita HM1203C 20 lb. SDS-MAX Demolition Hammer and the Makita HM1214C 27 lb. SDS-MAX AVT® Demolition Hammer—presented challenges. Although rated at 14 amps, they tripped a 20A circuit breaker. To avoid this, I ensured the demolition hammer was the only tool on the 20A circuit. Using demolition hammers can be labor-intensive, time-consuming, and requires multiple trips to Home Depot to rent the tools, which ate up even more time. For drilling, I used a low-powered Bosch Bulldog Xtreme to create the holes: a 3/4" pilot hole, followed by 1" and occasionally 1 1/4" holes. The instructions advise waiting 24 hours for the stone to cool after drilling, but I sprayed the holes with water to cool them immediately—just enough to darken the walls to a gray shade with a small amount of water pooling at the bottom. I mixed the Dexpan using a DeWalt cordless drill with a $6 paint mixer attachment in a e Home Depot 2 gal. Homer Bucket (RG502HD). The smaller bucket makes it much easier to pour the Dexpan into the holes. A funnel might be needed if you use a 5 gallon bucket. Twelve hours after pouring in the Dexpan, the concrete was shattered—I couldn’t believe it! The best part? The concrete broke into large, solid pieces for easy cleanup, and the Dexpan turned into a fine powder which was easily vacuumed up with a shop vac. I love Makita tools, but Dexpan really is a game changer.

## Questions & Answers

**Q: What type of drill is best?  i used my bosch 8.5 amp hammer drill with a 1” bit.   it lasted 10 minutes and shut down.**
A: I used a rather large hilti drill for mine with a 1.5" bit and even that thing was very hot to the touch after two 16" deep holes. I would do a few then let it cool. I'd say that drill is a good drill for most things but not for a 1" drill that's over 9" long.

**Q: Can you drill smaller than 1.5 inch holes in the concrete? I have a 1 inch drill bit - hence the question.**
A: You can use smaller holes, many clients including our own staff have had much success both with smaller and larger holes, however, the holes need to be closer together, no more than 6" apart and you must allow more time, we cannot guarantee the timing or results if you use anything smaller or bigger. Thank you for the great question!

**Q: I have a boulder 8' wide by 5 ' tall , will this work on it? And how far apart should i drill the wholes**
A: Wow that’s a big rock, mine was 1 1/2 feet tall and 3ft wide. I drilled 1” diameter holes 1 ft deep and 6-8” apart and it worked great over night. It says not to drill all the way through and about 1ft apart in a grid pattern. Good luck.

**Q: Can I just pour it into cracks of the big rocks and not drill holes**
A: I think it would work fine, efficiency would depend on depth and width of the crack versus the size of the rock. You'll need to dam the crack to contain it in the area you want to expand in. It is very runny when mixed and you do need to follow mixing and safety instructions. After the reaction takes place ( a day or so ), the stuff is as inert as limestone so no hazard that I am aware of. The primary ingredient is Slacked Lime & the Romans used it in cracks to break rocks for building roads so the history is extensive. I have some photos of concrete breaking that I did with it and I wish I could share them.  Try mail to toymkr at a o l dot c

### ⭐⭐⭐⭐⭐ Dexpan Works
*by C***F on April 25, 2026*

Works, just follow the directions. Even works with one inch holes. Expect some results in 24 hours. But, if you wait 48 or 72 hours it continues working and I got better results. Seems to work outside the temperature range as my temperatures varied from too low to too high for the ones I bought. Figure you might do about 15 holes with the 11 lb. size so you might consider buying the larger size because it might be cheaper in the long run.
