Rated 5.0 out of 5.0 by DM Ecobust Does work on granite
I used it on two different rocks too big to remove. One had three 1-1/2" holes drilled the other had ten 1" holes. The 1-1/2" holes cracked the rock in two days and the 1" holes did it in three days. Very surprised and happy.

Rated 5.0 out of 5.0 by ConcreteRemover Works great with concrete around low windows
We had to break up a 4'x3'x1' concrete stoop and after drilling mini holes, sledge hammer, circular saw, nothing budged it. We can't use a jack hammer as we have windows that are just about to grade. Heard about this product and ordered some to the correct current temperatures. After renting a hammer drill and 1-1/2" drill bit, we drilled 15 holes. We saw results within 7 hours but let it sit for 48 hours as the whole stoop was broken and ready for removal of pieces.
It didn't come in the bucket shown, but in a brown box with the bag and directions inside. Very easy to mix and you have to use the product within 10 minutes. We will be using this product on the larger rear concrete stoop too....next years project!

Excellent product that works exactly as advertised - imagine that!
The manufacturer should include mixing instructions with package - kind of a hassle to go online and download them. And make the mixing instructions applicable for using amounts less than the full 11lbs.

Rated 5.0 out of 5.0 by horase simply works
as the old saying goes, a picture is worth a thousand words. I used 1" holes, not 1.5" as speced.

Rated 4.0 out of 5.0 by DIYer Interesting product to learn.
Purchased to demolish huge coral stone in front yard. Required a lot of geometry because I was not about to mix the whole 11 pounds of compound per the instructions. Where I had success was when the drilled hole depth was at least the radius of surrounding stone to its edge. Pretty cool to see big chunks of stone lying on the ground 24 hours later. Concerned about the temperature range, next pour will be in the evening. This huge stone is in Florida.

Rated 5.0 out of 5.0 by jim489 Great product that works!
We had a large chunk of concrete in the yard that was the base of an antenna. It was about 3' deep so pretty much impossible to remove and all we wanted, was to take off the top 2-6” so we could plant grass. After drilling holes and filling with Ecobust, we waited a couple of days and, presto it was cracked to the depth of the holes. After that, simple prying with minimal sledgehammer work and the job was done. Definitely recommend this product!

Rated 5.0 out of 5.0 by Samm This stuff may seriously surprise you!
Had annoying boulder holding up my patio walkway project. Rented the hammer drill, drilled holes as stated on product. Poured product. After watching for a week, nothing had happened. I contacted Jason at Ecobust with all the details. He suggested I had used the wrong temperature spread product and offered to send me the correct type III for free. The type III was not available when I bought the type II as the product line had just been launched. Temps had dropped in my area considerably after I had ordered from HD initially. We had a night of heavy rain and warm temps. Woke up in the morning to find the rock in pieces and now easy to remove! So, it was probably too cold when I poured and probably did not use enough water. I have to say, I was seriously impressed with the effectiveness of this product and the help from Ecobust. Highly recommended and as easy to use as making pancakes.

Rated 3.0 out of 5.0 by JohntheEngineer Works OK - lots of Drilling
I had to break up concrete steps and a large landing. It was stong concrete, re-inforced with rebar and there were dowels pinning it to the pad below. I ordered two 11 lb buckets, it took 10 days to arrive at my house.
For the first bucket I drilled 3/4" dia holes with my hammer drill. I know it's less then recomended but someone said it would work. It worked OK, about a 4" layer broke off.
I rented a hammer drilled and drilled 1-1/2" holes for the 2nd bucket. It worked better (of course) but some of the ecobust stayed in power form and didn't work. A little frustrating after all that drilling.
For the rest of the concrete I used another product. It was available locally and worked better. I had to rent the hammer drill a 2nd time for the last of the concrete.
The 11 lb bags don't go very far if you're drilling 16" deep holes like me. But I wouldn't want larger bags, you only have 10 minutes to pour the material.
Overall it was a slow process but much better then renting a jack hammer.
