Expansive Demolition Grout 11 Lb. Bucket for Rock Breaking, Concrete Cutting, Excavating. Alternative to Demolition Jack Hammer Breaker, Jackhammer, Concrete Saw, Rock Drill (#1 (77-104 F))

We expected to demolish the colomb fadter as show in the video but it give 10% only

Used successfully to break up some large boulders in the garden. Did require some hard work to drill the holes to accept the grout but got there in the end.

This stuff is incredible. I was skeptical at first but am very pleased. Tried it on a basketball sized rock in an annoying place on the driveway before I do my big project. Drilled a 4” deep x1 1/8” hole hoping to just blow the cap off the rock so I wouldn’t hit it with the tractor while snowblowing. Came back next day and it was in three chunks! Very pleased. Note that instructions recommend pouring it first thing in the morning, so it has a chance to work during its “critical eight hours“ during the heat of the day. I was too cheap to buy a 1 1/2” bit, got the 1 1/8” for half the price. Seems to be working fine in the limestone I am dealing with. VERY HAPPY with this product. It is allowing me to turn a skidder trail into a road passable by cars and minivans. I have fractured a couple rocks and carefully blown the top 8” slab off others just by changing my techniques. WISH I NEW ABOUT THIS STUFF YEARS AGO!?!?! Why doesn’t Dexpan tell people about their product. BE PATIENT! Results after 48 hrs is always better than 24

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.

I needed access to my foundation but I had a massive rock next to it (almost touching the wall). The part that is visible in the pictures that I needed to break was about to 2 feet high and slightly more than 3 feet wide. I tried everything I could think of but I only made a dent in it. I broke concrete before and it fells like butter compared to this rock. I saw the Dexpan product. I wasn't sure I really believed the results could be as good but it was my only option left. I ordered it on Amazon and the next day I rented a rotary hammer with a 1 3/8 x 18 inches drill bit (they didn't have the 1 1/2 as recommended by Dexpan). I drilled the rock and then I filled the holes with Dexpan around 7 PM. I was really anxious and the next morning, as soon as I woke up I got out to see the rock, afraid it would still be intact but a miracle happened, it was completely cracked. It was cracked all the way down to the bottom. If you follow the instructions it really works. Highly recommended product! 100% satisfied! Hopefully I won't need it again in the future but I need to, I will not hesitate to buy again.

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.
