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)

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.

I love using this stuff. Make some holes, mix with water, pour, and wait. No jack hammering, sledging, or hidden dangers. In tight quarters (crawlspaces) or remote places this is ideal to break up concrete. This picture is not with recommended hole spacing but it still did it's job without heavy equipment getting near the sliding doors or annoying the neighbors with loud noises.

Works ast says. Easier than using sledge hammer and saves time

Not enough product for the price

This stuff works great! I used it to split a 1’x1’x7’ solid step. I drilled 3/4” holes instead of the recommended size but spaced them about 8” apart. Less than 24 hours later I was able to pry the pieces apart. I also scooped out only the amount needed and eyeballed the amount of water making a pancake batter like consistency. I took the time to blow all of the concrete dust out of the drilled holes as well. I like products that still work when you go outside of the recommended procedures.

Worked great

Biggest disappointment. Tried it twice. Second time I went with type 1. Holes drilled with 1.5in bit, cooled, water was ice cold and measured down to the last ounce. Mixed perfectly and poured immediately. Holes covered with straw immediately after and was poured when temps were low outside. All it did was go poof abd shot powder everywhere again. No cracking. Do not recommend

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.
