Sven, I recently had to drill a 2" hole in a concrete tilt up building South of the border. I drilled a 1/4" hole as a pilot and picked the rest of it out with a screwdriver. My fellow worker enlarged a 3/4" hole to fit 1" EMT by driving a piece of scrap 1" conduit through the 6" wall with his 16 ounce hammer. It took less than a minute. They need to get the aggregate/cement/sand ratios down a little better before you guy's criticism has much validity
