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

Works Amazing. Be sure to order the right temperature for your location. The shadows of trees will slow down the process. Still worked great but took a bit longer to crack. Real easy to use, be ready you have to work quickly. Starts to thicken up quick. We used it for ledge pokers in the grass. Worked on granite. Over all does what it’s supposed to do. Definitely recommend.

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.

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.

Not enough product for the price

After drilling the holes and adding the Dexpan I let it work for a week. Everyday I would check it and notice cracks in the rock getting larger. It may take several applications for larger rocks.

I ordered this product to break this large rock in 2 parts, before receiving the product I already started drilling the holes however, I only had a 1 inch bit. Later when the product arrived I realized I didn't have my holes spaced correctly how they wanted them and I didn't have them as deep as I should. But understand my drill bit was only 1 inch wide by 14 inches long and to go any longer or bigger then I would have had to buy a bigger drill and bit and that was too costly for this project. So I used what I had and it worked extremely well. My rock was over 3 feet thick and 6 feet wide and not able to move it until I had it in 2 pcs. Thank you very much guys, awesome product, I love it!

We needed to demo a very old and hard cinder block vertical wall that our 18v hammer drill wasn't touching. I think it just is not good for this application, and I'd suggest a pass to others for block walls. Although for the most part it was due to the hollow area in the cinder block, even where we were able to get drilling in the solid areas, the Dexpan just seem to dry out to fast. We kept trying to add water, isting it with hose poking small holes into it and drizzling in more water, but it was a fail for us. Had Dexpan had information advising against effectiveness on cinder block we would have passed, so 1 star lost for lack of application information on a very common wall type. 1 stars because of how fast it dried out and no instructions advising to pre-wet old/dry concrete. If you try this on another type of cement, I advise soaking the cement and holes a bit so it doesn't immediately suck all the water out of the dexpan. In the end we rented an 11 lb corded hammer that helped us with the job by targeting grout lines. A 20 lb rental would have sped it up in retrospect but it was so heavy we wet smaller. Our wall was maybe about 60-80 sq ft of block area. With the rental it took about 5 hour to knock out, one on the electric hammer and another swinging a small hammer once grout lines were broken up some (our local store was out of real sledge hammers, which additionally would have been a time saver). Tough jobs, wish you the best.

This stuff is amazing for thick concrete. It will save you from the jackhammer and save you a lot of time in general

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

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.

Celui-ci na aucunement fonctionné!! Le vert par contre lui a tres bien fonctionné. Je recommande celui avec le couvert vert et pas du tout celui-ci!
