Dexpan Expansive Demolition Grout 11 Lb. Bucket for Rock Breaking, Concrete Cutting, Excavating. Alternative to Demolition Jack Hammer Breaker, Jackhammer, Concrete Saw, Rock Drill (Type 2, 50-77° F)

directions need to be read and understood, it has a danger to users in hot weather. it expands! that said, the smallest hole i filled was a 3/8 to remove concrete from metal poles so that they could be reused. i also drilled 3/4 holes to break up thin walls for repair to the unit. it works over night in cooler weather, but you will see the start of the fractures in about 8 hours. silent destruction, (apart from the hammer drill) good stuff, experiment and learn how to use before taking on larger projects.

Worked great!! Mixed product to a thick pancake batter, poured into drilled holes . Checked 2 days later and had many cracks. Made removing pieces of cement much easier and did not have to rent jack hammer

This product is incredible and a must-try! Dexpan demolished 6,000 psi CTS RapidSet 24/6 concrete with ease. The instructions recommend using 1 1/2" holes, but I achieved these results with 1-1/4" and 1" holes. Despite my shortcuts, Dexpan delivered outstanding results! I'm a huge fan of Makita, but their demolition hammers—specifically the Makita HM1203C 20 lb. SDS-MAX Demolition Hammer and the Makita HM1214C 27 lb. SDS-MAX AVT® Demolition Hammer—presented challenges. Although rated at 14 amps, they tripped a 20A circuit breaker. To avoid this, I ensured the demolition hammer was the only tool on the 20A circuit. Using demolition hammers can be labor-intensive, time-consuming, and requires multiple trips to Home Depot to rent the tools, which ate up even more time. For drilling, I used a low-powered Bosch Bulldog Xtreme to create the holes: a 3/4" pilot hole, followed by 1" and occasionally 1 1/4" holes. The instructions advise waiting 24 hours for the stone to cool after drilling, but I sprayed the holes with water to cool them immediately—just enough to darken the walls to a gray shade with a small amount of water pooling at the bottom. I mixed the Dexpan using a DeWalt cordless drill with a $6 paint mixer attachment in a e Home Depot 2 gal. Homer Bucket (RG502HD). The smaller bucket makes it much easier to pour the Dexpan into the holes. A funnel might be needed if you use a 5 gallon bucket. Twelve hours after pouring in the Dexpan, the concrete was shattered—I couldn’t believe it! The best part? The concrete broke into large, solid pieces for easy cleanup, and the Dexpan turned into a fine powder which was easily vacuumed up with a shop vac. I love Makita tools, but Dexpan really is a game changer.

It really works , it takes longer on cooler weather but it works

The biggest drill I have is 7/8 inch that came with my Chinese hammer drill. So I drilled four holes, 9 inches deep. After about 24 hours a crack appeared and reached a width of about 1/4 inch. I had a mini excavator to use to separate the rock and it came apart. Without the machine a steel wedge might have worked. After I removed the first part of the rock, I drilled four more holes and cracked it again and now what is left is below ground level. Calculating the amount to use resulted in a lot of waste. My four holes only needed about two pounds of material. I calculated .29 oz of H2O per ounce of grout. So 9.25 oz H2O for one pound grout. The stuff is made in China and In my opinion is over priced compared to the cost of material used to make this stuff but it got the job done so it was worth the cost to me.

Magic! This stuff is amazing. I am in the process of exploding 5 Sandstone boulders. I drilled some 1.5 inches nch holes and some 1 inch holes. Mostly 1 inch. 11-12 inches deep. Pro tip: use a vacuum to suck up the dust from the holes. I poured the slurry at 4 pm at 60 degree outside and now it is 1 pm the next day. One rock split in three at midnight. The others are slowly cracking nicely. The huge one I drilled 5 holes in will take time. Cracks are developing. Next day you can add a few teaspoons of water as it starts drying. Just wow! Hard part is hammer drilling the holes. See the photos to believe it. Now I can move my dining table to this space after building a 20x20 patio. Best $50 I spent!! Funny thing is after rock separates you expect a hard cylinder but it’s just powder. I saved some in a bucket and check to see if it can be re-used! Last photos shows the powder after expansion.

Fake product doesn't do anything at all when mixed with water nothing breaks nothing demolished. Very runny and difficult to apply to holes as well. Don't buy this fraud, poor value for money. Very difficult to open.

This is a great product. I wore myself out jackhammering solid cement stairs that had been poured onto the foundation footing, thus breaking the footing as the stairs settled over the years. I only got through the top step. Heard about this product and didn’t want to pay to have someone else demolish these. I bought a Vevor drill, Bosch hammer drill bits and Dexpan. All of the products were fantastic. Way more manageable than jackhammering for hours. The product says 9 lineal feet for an 11 pound bucket (8 lineal feet is probably more accurate, so plan accordingly). If you do steps, don’t pour them all at once. Each level requires a 5-10 minute time gap between pours.
