Rated 5.0 out of 5.0 by Stonehaven Really works
I had a block of concrete in the front yard which was used as a barrier between the lawn and the trees. I tried breaking it with brute force but didn't make much progress so I looked for an alternative and found this product. I didn't realize that this product was sold locally so plan accordingly. The hardest part of this project was drilling the holes. I used a hammer drill with a one inch masonry bit. The drilling took me off and on about five hours over 3 days. I was a little worried that I need to use this product on a weekend that was cold (recommended temperate was 77f to 104f but it was in the 70s during the day and 50s at night) so I mixed the product and poured it into the holes around noon when the sun was out. I read that most of it works in first four hours but whe I checked back about 5 hours later and was disappointed that there were only a few hairline cracks. My first reaction was that I wasted $42. However, I checked back a few hours later and noticed there were hairline cracks between all of the holes. The following day the cracks were wider and I could have disposed the pieces the next. However, since I'm slowly dumping the blocks in my trash, the block has been sitting there for days and now the cracks are 3/8 inch plus.

Rated 4.0 out of 5.0 by cr It did ok
It did ok. It took a good 48 hours prior to breaking up my stoop. I did a second round on it . The second round didn't do as well as the first. I will still have some work to do, but its a good start.

Rated 5.0 out of 5.0 by Ranchman Spilt a granite Boulder
This stuff really works. I rented a pnuematic rock drill and drilled 5 holes approximately 3 feet deep. I was only able to fill 3 1/2 holes with the qty of dexpan that I purchased. The first day, nothing happened. 2 days later I saw a small crack. Within a week a 1/4 inch crack appeared. This is a huge boulder and I don't know how much is buried in the ground. I will need to use more holes to actually split the boulder apart and separate the pieces but this was a great start. I previously tried a jack hammer and the boulder just laughed.

Rated 1.0 out of 5.0 by Sue 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.

Rated 5.0 out of 5.0 by ds Worked perfectly
This worked as advertised. I used it to break up entryway steps. The concrete was thicker than I expected, but the Dexpan broke it all the way through, 18"at the thickest spots. This in spite of the fact that the weather changed and the overnight lows dropped below the temperature range recommended.

Rated 5.0 out of 5.0 by Tbone When used correctly it works great for breaking quartz safe way to hardrock mining
Good product it really does what it advertises. As long as you use it correctly. We have been using it in quartz for mining, drill your holes pour your Dex Pan then in the morning you have gold. I will be using for years. Make sure you get the right temperature for your application. There are three types.

Rated 5.0 out of 5.0 by Moz Excellent solution to hard problens
My ranch is in the central Texas hill country and bedrock seems to always interfere with road drainage. Before finding Dexpan I had to rent a jack hammer to open obstructions in ditches. Now I just drill a few holes, mix the Dexpan and let it do the work. Saves time, money and my back. Amazing stuff.
