Produit qui démolit vraiment des rochers

تم التجربة على صبه لكن لم تنجح التجربة في التكسير

I'm putting on an addition to our house. When digging the hole for the foundation, we hit ledge about 6 feet down. This would have severely limited our basement ceiling height. The ledge consisted of a mix of gray NH granite and some insanely hard black rock. I had to take off about 1.5 feet of ledge to get to a 7 foot basement ceiling. We will end up owing the excavator about $1000 in machine time for beating on it with the hammer he has on his skid steer. A larger machine was not available. For that machine time, we took out the two highest peaks, but the vast majority of it remained. So I gained about 1/2 foot this way. The excavator did not have any good solutions for me. I went on the web and found Dexpan. Watched a few youtube videos and convinced myself that I had a shot at this. The excavator and foundation guys were both very skeptical, but hey, when you're desperate, you'll try anything. The first day I drilled 30 holes as a test. The next day I saw a few cracks appearing. I ended up drilling about 120 3/4" holes 10 inches deep each. Holes were drilled about 6 inches apart, and were carefully chosen to take advantage of existing fracture lines in the ledge. Took about 8-10 hours of drilling time. The Dexpan succeeded with cracking up the ledge to the extent that the excavator could come back with his skid steer hammer and bust it all out in about an hour. I got an additional 1 foot of ceiling height out of this and now we are finally ready to pour the foundation. DEXPAN ROCKS!!!!! Forgive the pun. By the way, I think I would have been better to have ordered lower temp range Dexpan. Some of my cracks took a couple days to even start. I think with the lower temp product, it would have gone faster.
