Rated 5.0 out of 5.0 by DiehardDIYer DIY Rock Removal
Used to break up rock during road building and maintenance of private graveled roads located in North Georgia mountainous terrain. Worked on state, blue rock, and quartz rock embedded in clay. Conveniently packaged in 4 bags within a resealable plastic bucket. One bag (11 lbs) filled about 15 holes 6 inches deep with a diameter of 1.5", spaced 8 inches apart. Mixing is effortless with 1.5 liters of water in a two gallon bucket. After 24 hours quartz had several cracks but only 20% or so was removable. After re-wetting the mortar and waiting another 24 hrs all the rock that needed to be removed for road building purposes was easily removed by backhoe but could have been pried out manually. A hammer drill is required to drill holes. After renting an electric one from HD for a minimal amount I decided to purchase one (although a bit larger one) since I will always be battling rock in my area. I have used professional blasters on a larger scale removal of a 12ft h x 4ft d x 45 ft w open face rock/slate wall. Even with the substantial investment in purchasing the drill and generator to run it, this method is far, far more cost effective than hiring professional blasters to remove smaller nuisance rock deposits. The cost of the product itself will offset the cost of my new equipment within use of two buckets or 120 holes versus hiring professional blasters.

Rated 4.0 out of 5.0 by ProjectGirl Great product, challenging application
This really does break concrete. Used it on my 2-3'tall x 2 1/2' wide x 35' long old footer wall. Used a hammer drill to make 16" holes 8" apart. Drilling those holes was hard! I rented a beastly hammer drill, and had to put my entire body into it to get the holes drilled. However, the product worked just like they said. If you have a better way of getting the holes drilled, you will be great shape!
