Expansive Demolition Grout 11 Lb. Bucket for Rock Breaking, Concrete Cutting, Excavating. Alternative to Demolition Jack Hammer Breaker, Jackhammer, Concrete Saw, Rock Drill (#1 (77-104 F))

Used successfully to break up some large boulders in the garden. Did require some hard work to drill the holes to accept the grout but got there in the end.

Really impressed with the product considered I was skeptical. I had a fairly large granite Rock that I have been wanting to get rid of for years but it was much to heavy to move. Tried drilling holes in it, used a concrete saw to cut into it .. for the life of me I could not break it down into smaller pieceS due to its size. This product did what I couldn’t do within 24hrs. A little pricy but considering it resolve a long due problem for me worth every penny. Amazing and thank you for the great product. I showed my parents and friends and my dad has already purchased and used it on some large rocks at the cottage he wanted gone. Works there as well. MAKE sure to follow instructions exactly as described. In my cases I divided the volume into 3 so I gave myself 3 attempts to achieve what I needed since I had more than I needed for my rocks. It did the jump 1st time around... used a second batch to break down the rock even more... all I can saw is amazing :)

We expected to demolish the colomb fadter as show in the video but it give 10% only

A safe and effective way to break up rock. I had a troublesome piece of shale in my driveway. I was unable to use heavy equipment to remove it due to a buried cable nearby. I drilled a series of 1-inch holes, ten inches deep on an eight-inch grid (about 30 holes total) then filled with the Dexpan slurry. In 12 hours, the rock was completely shattered and easily removed by hand. I was able to use a funnel to fill the holes as the mixed product is about the consistency of pancake mix.

I was skeptical on whether this product would work in breaking up a tire filled with 250lb of concrete reinforced with rebar. I only had a 1" bit (instructions called for 1.5") so I made my holes 6" apart instead of 1'. In about 12 hrs we had cracks and 24hrs it was ready to be smashed apart with a sludge hammer. Very impressive stuff.

The Product really does work. I live in Northern Maine and we have a lot of huge garnet rock. I needed to remove this rock so as not to hit it while plowing snow in the winter time. I had a friend with an a Large Linkbelt Excavator try to move it, the Excavator could not even budge it, the machine stood up on its side, with rock not even budging. So then someone told me of this product and though I would give it a try, for the price, its worth a try. Not really believing that it would, so I proceeded to do as the instructions read, however, I only had a 1" drill bit and drilled the proper amount of holes as needed. Mixed and poured into the holes and walked away for 48 hours and its doing the job. Many people are asking does it really work, I have taken pictures of the cracking so as to show them, and of course the rock missing is also a testimony to the produce.
