Dexpan Expansive Demolition Grout 11 Lb. Bucket for Rock Breaking, Concrete Cutting, Excavating. Alternative to Demolition Jack Hammer Breaker, Jackhammer, Concrete Saw, Rock Drill (Type 2, 50-77° F)

directions need to be read and understood, it has a danger to users in hot weather. it expands! that said, the smallest hole i filled was a 3/8 to remove concrete from metal poles so that they could be reused. i also drilled 3/4 holes to break up thin walls for repair to the unit. it works over night in cooler weather, but you will see the start of the fractures in about 8 hours. silent destruction, (apart from the hammer drill) good stuff, experiment and learn how to use before taking on larger projects.

Worked great!! Mixed product to a thick pancake batter, poured into drilled holes . Checked 2 days later and had many cracks. Made removing pieces of cement much easier and did not have to rent jack hammer

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.

Not enough product for the price

Amazing product. After battling with cement saws and jackhammer in a small space, I ordered this. Our holes could only be 3-4" Deep and 3/4" thick. Next morning, my husband said it turned back to powder. The next day we went to clean up and try pounding, but to our surprise the slab was all broken up. I guess sometimes it just takes a while. I will use this for all my stone and concrete demolition.

So about a year ago, I get it in my head I really want to remove this boulder in my backyard, I go to Home Depot, rent a huge jack hammer and spent 10 hours straight chipping away at it almost to feel like I was getting nowhere. It turns out it was very hard granite and alas I was defeated, and kind of gave up altogether. Recently I had done some research and came across Dexpan and I must say, I was skeptical. So I ordered a bucket for $39 and luckily my old job let me borrow their combination rotary- jack hammer with an 1 3/8 bit. I had read they recommended 1 1/2 but I figured it couldn't be a big deal. I spent about 7-10 minutes a hole drilling holes 18 inches deep across the boulder about 9 inches apart until I figured I had it pretty much covered and then I watched the Dexpan video one last time. It was very straight forward, even down to the use three water bottles of water for one 11 lb bag. I mixed it all in a 5 gallon bucket and started pouring it in. I filled probably about 16 of the 21 holes I drilled and felt like an idiot because I was on the fence about ordering two buckets but I figured let's see if this works before I order another. I come back about 5 hours later, and I see nothing, no cracks, and now I'm thinking this was a total scam but I had to leave for work anyway so I'm like let's see how it looks in another 8 hours. I can't begin to describe how thrilled I was when I came home from work, there was giant cracks all over the boulder from the holes I had filled and I had to restrain myself from starting to pry at it because it says wait 24 hours. When that time finally did come, I went out there with a san angelo bar, and that boulder just started breaking apart at the seams. I've since ordered a second bucket and as I type this, I have fresh Dexpan in the rest of the holes and I'm waiting for it to break apart what's left of the once impenetrable rock.

Fake product doesn't do anything at all when mixed with water nothing breaks nothing demolished. Very runny and difficult to apply to holes as well. Don't buy this fraud, poor value for money. Very difficult to open.

100% would recommend to any one who has an significant concrete demolition work, but doesn't have access to heavy duty/industrial jack hammers, or are in a residential environment and don't want to be hated by your neighbors :D I had to break up a set of old concrete stairs on my own, and this just worked exactly as advertised. I didn't have the recommended/required 1 1/2" drill, but it worked with my 1" drill. It says for best results leave for 24 hours, and while that certainly does the bulk of the work, there were a few cases where not everything had broken, and after chiseling for a few hours I called it quits for the day, and the next morning found that the regions had further broken, so if you're in that position it might be worth giving an additional day to maximize the amount of success. One thing to note is that it does result in a lot of dust that I assumed would not be healthy - I don't recall in the instructions said to wear a mask, but I did and I'd recommend it, but also it was helpful to have a shop vac (or whatever) around while pulling the broken concrete apart.
