Dexpan Slow Explosive In Ground Granite

Cutting a trench through granite to my cabin was tough. Here I try Dexpan slow explosive vs. 4 days with a jackhammer. Dexpan does not recommend its products for use on stone that is in the ground, but I was happy with the results. It needs a few days to work, but I've got plenty of things I'd rather be doing than running a jackhammer.
