Rated 3.0 out of 5.0 by QBur I hope it is NOT as misleading as the picture
I purchased ECOBUST 11 lb. Concrete Rock Breaking Demolition Agent from the reviews I have read. I ordered and had it ship to store. When I picked it up and opened the box I was appalled to see a cheap bag rather than the bucket Home Depot advertises in the picture of the product. I have NOT used it yet but I sure hope it is NOT as misleading as the picture in the ad on the Home Depot’s web site

Rated 5.0 out of 5.0 by Jeremy Great product, wrong package
Worked as expected to break a large rock in my basement, which I broke a hammer drill bit in and was unable to budge with a jackhammer, so I was happy when this product cracked the rock with ease. Unfortunately, I did not get the 11 lb of product that I ordered. Closer to 3 lbs in a plastic bag that made my wife nervous it would bust open at any minute. No instructions and sparse labeling came with the package, not even informing me what type of product I had (e.g. Type I). Good product, but poor package and delivery.

Rated 5.0 out of 5.0 by Cementbuster Very plesently suprised!
Had a large front step.6 foot wide and solid poured cement. Considered using a Jack Hammer but the dust and mess and time it would have taken made me do a little research. Found this product and thought why not try it. Drilled 1 inch holes 8-10 inches apart. In a grid pattern. Mixed the Ecobust with water following directions, and poured into holes. Covered over night. Woke the next morning and it was all broke up into manageable pieces. "Mostly". Still had to take a sledge hammer to get into movable sizes.
Would highly recommend this product before renting a Jack Hammer. $100.00 a day.

Rated 5.0 out of 5.0 by Scott I Really Works
In searching online I came across Ecobust , I am generally a skeptic about products like this and it looked like they were making some lofty claims. Rocks are hard to move without heavy equipment and I had five very large and heavy rocks in the way of a fire pit path. As with other reviewers, the same ideas came to mind, explosives, heavy equipment, laborious digging and lifting and none were a good option. I figured for $35, why not give it a try. I used a hammer drill to bore 1" holes 6 to 8 inches apart and about 8 to 10 inches deep. The rocks were all between 2 and 3 feet in size and over 1000 pounds. The drilling wasn't easy but within six hours of pouring in the slurry in the holes three of the rocks were so cracked up that I could pull them apart by hand without any tools. One was cracked the next morning to the same degree. The last was undrillable (with my tools) so that required a lever bar and a strong back. a large rotary hammer may have bore through this last rock.
Overall a great product that really works and is easy to use. The instructions call for 1.5" bore holes but 1" worked well if the spacing is closer. With a bigger drill and 1.5" holes I probably could have drilled fewer holes but I'm very satisfies with Ecobust!

My goal was to separate my outside porch from the house concrete slap without damaging the foundation; There wasn't any expansion joints. I removed the majority of the porch with a sledge hammer. The last foot I drilled 3/4" holes 3" apart and the next day my goal was accomplished.

Rated 5.0 out of 5.0 by RaytheArchitect A very forgiving product
Used this product to break up a concrete footing for a 4" steel pipe that formerly had a C band satellite dish on it. the concrete probably weighed 800 lbs. or more and was not moveable without some heavy equipment. My options were to hire a back hoe or rent a big chipping hammer. Both of these options were fairly pricey. While roaming through HD one day I spotted this product. It seemed a little pricey but hey if it works it will be worth it. Well it worked even though I didn't follow the directions to the letter. I didn't have a 1 1/2" drill but I did have a 3/4" so decided to try anyway. Since I didn't have the larger drill I put the holes about 6" apart instead of the recommended 18" and I even just mixed the slurry by eye. After 24 hours no results but the next morning the concrete had split into 2 pieces. The process had to be repeated a couple more times to arrive at chunks that can be lifted by hand and to drill holes that are fairly vertical. If the holes are at an angle that allows the slurry to leak out it probably won't work.
Recommendations; first follow the directions on the product if at all possible. If you do not have the 1 1/2" drill use as large a drill as you have, I would say at least 3/4", and space the holes closer together. I would also recommend mixing the slurry in small batches by weighing out the powder and adding the amount of water by proportion. I used 2 lb. powder to 1/3 L. of water. Mix the slurry well and continue to mix as you put it in the holes. It has a tendency to settle. Also make sure the holes are empty. I flushed the holes with water then blew the water out with an empty garden sprayer. The product isn't recommended for concrete slabs less than 6" thick but as before I decided to try it anyway. Well it worked again.
Clean up is simple and other than the powder stage, like concrete or mortar mix, tends to get blown around during the mixing so do it outdoors. I found mixing in small batches the best approach since it's difficult to estimate exactly the quantity needed.
This is a very forgiving product and for me it saved money and a lot of nasty work.

We have an old house that had a poorly designed concrete steps into the back yard, so we decided to demolish and build new. I was somewhat skeptical that this would work. But I followed the directions and drilled a series of 1.5 inch holes in a poured concrete steps. In three hours the first cracks appeared and by morning a half inch wide fissure had split the steps into sections. A few whacks from the sledge finished off the job.
The only problem that I had drilled two of my holes all the way through and there was no cracking at those holes. However, the product must have stressed the concrete so that a few swings of the sledge smashed it to manageable chunks.
