Review on 🔨 Dexpan: The Ultimate Demolition Excavating Alternative Jackhammer for Industrial Power & Hand Tools by Shawn Jimenez

I'm sure in the right situation this is a great way to split concrete. Everything went wrong in my situation and it's probably my fault, but all the holes burst and it was like bombs exploding, one after the other, with a loud bang, ejecting a powdery solution in plumes 20 or 30 feet high. , and to throw mortar everywhere. Really quite dramatic! I'm aware of two factors: After purchasing this product, I read that it's only good if you can drill a hole 7 inches deep or more. I break thinner concrete and can only drill 5" holes. And my holes were wet. I bought Dexpan for the right temperature in my area. I'm wondering if the chemical reaction generated enough heat for the steam explosion - similar to popping popcorn - or if it was just the strength of the grout. I stood by for about 2 hours to make sure no one approached where this was happening. So it's probably my fault. But here's how things can go wrong.
