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.
