Concrete demolition and rock breaking has never been easier with Dexpan Expansive Demolition Grout. Poured into drilled holes, Dexpan can break concrete and rocks safely and quietly, while providing silent cracking.
This stuff works. I've been using it for months to break 8600 PSI rocks. Over 10,000 pounds of rock busted using a 1.0" hammer drill with Dexpan. It is a huge time saver and gets the job done without large equipment.
