11 lb. Bucket Type 1 (77F-104F) Expansive Demolition Grout for Concrete Rock Breaking and Removal is rated 4.3 out of 5 by 44.
Rated 5 out of 5 by from Dexpan - amazing We have a camp in ME with a 40' dock that was slowly being pushed away from shore by a huge boulder that was being pushed by expanding ice each winter. There wasn't any way to bring in heavy machinery and we had to be careful with the dock and stairs - so this had to be done by hand, After a full day with drills, hammers and wedges we didn't come close to clearing enough away to make a difference. A friend said he heard of Dexpan and thought it might work. I ordered it, drilled a few holes, poured Dexpan into the holes and walked away. I came back the next weekend and the rock was perfectly separated along the line of holes. I simply popped out a few pieces and was left with a 5 in gap between the boulder and dock. This product produced the exact results I was looking for - could not be happier!

Rated 1 out of 5 by from Dexpan not worth it Do not buy this stuff. It sort of worked, under ideal conditions, ultimately creating a smaller, but still unmanageable hunk of concrete. By the time you order this, get it, drill a bunch of holes (not easy and you still have to buy or rent the tools for this), wait to see if it works, add more water, wait again, then chip away at the concrete anyway, you could have just jackhammered it. Too bad, I wanted to be happy with this product.

A company wanted $300 to remove this large piece of concrete. I did it for $40 with Dexpan. It didn't break it up as much as I would have liked but that could have been due to my hole placement. It was an odd shaped piece. 100 times easier than using a jackhammer. It does what it's supposed to.

I drilled the holes with a 7/8" bit, which was smaller than what was recommended since I didn't believe I would be able to operate a larger drill that could accommodate a 1.5" bit . There was no visible reaction during the first 36 hours after I had poured in the Dexpan, and I was thinking that the product wouldn't work because of the smaller hole diameters. The second day, however, it started to rain and within the next 6 - 8 hours, large cracks appeared as I had seen in the videos. When I pulled the pieces apart I found quite a bit of dry dust in the holes, which more than likely meant that the concrete had been porous, and absorbed the water before it could activate the expansion. The air temperature was about 55 F, and it is possible that the process had been faster on a warmer day. Despite having to wait a bit longer than I originally anticipated I was impressed with the results, and relieved over the procedure not being more complicated than you typically see in the demonstration videos.

Rated 2 out of 5 by from Could've worked better Results were disappointing. I drilled the holes as instructed, poured mix and waited pass the 48 hours. The temperature may have dropped a little below the 50 degrees minimum. As a result, there were only small fragments of the large rock that broke.

Rated 5 out of 5 by from Dexpan is no joke I usually don't take the time to rate products, but this one is different. I heard about Dexpan from a friend, did my own research and gave it a try. I was a bit skeptical because the concrete I was going to remove was bordered on 2.5 sides by the house and concrete front walk way. I drilled the holes every 9" instead of the recommended 12" to assist in fracturing. Twenty-four hours later, my concrete front porch was rubble. I had read that watering the Dexpan down a second time will increase fracturing. Not only did it fracture more, but it raised it up (probably due to it pushing against the house and walk way and no place for it to go but up, I guess). The removal of the concrete chunks was very easy. This stuff is no joke!
