Rated 4.0 out of 5.0 by Pooldemoguy Dexpan works as advertised.
It's not perfectly clear what temperature to use it. I realize it says 50 to 77 degrees. Does that mean it has to stay above 50 degrees at night since it takes about 3 days for it to work? I wait until it's in the range day and night and it works as advertised. I'm breaking up two swimming pools.

Rated 5.0 out of 5.0 by oldhandyman Dexpan worked for me!
My latest project was the demolition of the concrete stairs next to the sliding glass door that opens onto the deck. The deck was built over the stairs and was partially resting on the stairs. Over the years the concrete stairs had been settling and pulling away from the house and sliding glass door putting some stress on the deck. We have been planning to replace the old sliding glass door but were concerned that there was no longer a good base since the door frame was sitting on the top step which had moved away. Hoping for an easy way to break up the concrete stairs, I found a product called Dexpan which is an expanding mortar. I drilled 1-1/2 inch holes in the concrete, mixed the Dexpan with water, and poured the liquid into the holes. By the end of the day substantial cracks had developed in the concrete. Unfortunately the pieces were still too big to remove easily so I got some help to break the concrete into smaller pieces with a rented jack hammer. The product worked as advertised but I should have paid more attention to hole pattern in order to break up the concrete into smaller more manageable pieces.

Rated 5.0 out of 5.0 by PharmGirl Dexpan is AMAZING!
I have a set of outdoor concrete steps in my house that had to go.... sledgehammers, chisels, hammer drill chisel.... did nothing but aggravate me! My next step was a jackhammer until I found out about Dexpan. A little more than halfway done and the hardest part is drilling the holes and clean up. It's quite satisfying leaving the Dexpan to do it's work and coming back the next day to some nice deep cracks!! Love it and have recommended this product to several people already!

Rated 5.0 out of 5.0 by Shorty Good stuff
Had a slab of concrete nearly 20 in thick in spots, too much for me to jackhammer. Follow the Dexpan instructions, make sure to drill down to the recommended depth.

Rated 5.0 out of 5.0 by MaxxV Dexpan is a great alternative to other demolition
Not able to break up cement foundation after trying impact hammer, sledge hammer and front loader. While looking for a reasonable alternative, I came across Dexpan! Drill a few holes, fill with Dexpan ..... sit back and wait. I was pleasantly surprised at how well this product worked. Cement foundation cracked in to smaller pieces overnight, most pieces were removable with no further work. Great Stuff!!

Rated 5.0 out of 5.0 by Paironman Retaining wall demo
Product works beyond expectation. I'm removing 80' or 8"x 48" reinforced retaining wall. It's made the job so much easier. Drill, pour, wait a couple days, and pick up the pieces and move on. I have used both a hammer drill and a core drill and have gotten the same results. 1",1-1/8, and 1-1/2 bits. I highly recommend this product if your cheap like me and can't fathom renting machinery or having someone else do the work. 40' down 55lbs used an 40' to go.
