Questions & Answers

Can I use dexpan to remove 2" of decorative concrete in the middle of stoop treads on concrete slab?

Can I drill less than 1.5" holes for dexpan?
Asked by: Vonny
I doubt this is what you're looking for. You've probably done the job already since your posting, but this product works well using a 1 1/2" diameter hole that's at least 8 to 10" deep minimum.

44 lb. Box Type 2 (50F-77F) Expansive Demolition Grout for Concrete Rock Breaking and Removal is rated 4.6 out of 5 by 72.

No doubt, if I knew of another way to break a boulder tyrant doesn't require any effort, I'd have gone that way. But otherwise, this is the next best thing. The hard part is the drilling these 1 1/2" holes. Once you pour this in the holes, it'll take 4 to 6 hours to see the beginning of the cracks. However, this just keeps on working. After a couple of days, the crack is now much longer and wider. And the boulder I worked on must have weighed well over 5000 lbs. I only saw a portion of it as mosy of it was buried in the ground and what I saw was about 6 feet long and 2 feet wide.

The only problem I have with the product is the age... the box was labeled with 3/22/2016, which means it is a little over one year old by the time I received it. All expansive mortars have a shelf life of about one year, and after that it is not as effective as fresh. I know this because I purchased one metric ton of it from a Chinese supplier several years ago, and they told me about the age issue at that time. For $100 I expected something a bit fresher.

Works great, just wish there was a way to have used it on thinner slab as well. Slab was 24' x 24' and averaged 12" on outside and tapered to average of 5" about 14" into center. Started with concrete saw (useless), then hand sledge, then found out about Dexpan. Drilled dozens of 3/4" holes only to find they needed to be 1 1/2". Rented larger drill and punched holes along perimeter. Then rented jack hammer to finish up thinner center and larger pieces that I did not drill for Dexpan. Ordered the 44 pound package and it was not enough. Ended up getting another 11 pound bag to finish the job. Very impressed with how fast the product arrived after ordering and Michael at Dexpan was very helpful when I contacted the company with questions. The only very small problem I had was that the "slurry" kept trying to settle and I had to stir it after pouring each hole.

The Type 3 as well as Type 2 performed the same, it is not the air temperature but the rock temperature which I believe impacts the performance. I observed if the sun is not beating down on the rock and warming it up the time it takes to cure and crack is tripled. I also noted it helps to water the drilled holes as it cures otherwise it powders.

Will continue cracking the concrete for several days if your piece is really deep. Mine was 4x4x5 foot and cracks kept appearing as I dug around the perimeter after removing the initial fractured pieces. Wetting the concrete helped after the stuff had worked overnight. Crack size seemed to double in the next 8 hours.

I have to drill a 1 1/2" hole, spaced about 12" apart, but it is relatively inexpensive, and no specialist or certification is required, compared to using explosives to break rocks. And this stuff really breaks them! You have to wait a day or two, and you have to make sure the rock temperature is in range.

This is a follow up to my first review when I had received but not used the product. This product is amazing. The hardest part is drilling the holes (very dusty). Destruction of my concrete stairs was complete. I followed the instructions as close to the letter as possible and the product delivered. My steps did have some 1/2 inch horizontal rebar which was no problem.

Rated 4 out of 5 by from Really works Had concrete steps to remove to build back deck. This stuff broke it up into movable pieces. In 24 hrs there were cracks but took 72 hours to create huge ones. Wasn't a big deal as we had time to wait. Didn't work as quickly on sidewalk. Might have been temperature issue. But let it sit for a week and then sidewalk was broken up too.
