hey...on one of mikes episodes i noticed that he was attempting to run the hose of a pump tuck for a footing of a building....and in another he helped jack hammer out a cement drum truck. but i also noticed that he didnt show where the cement came from. i myself work at a concrete plant. we have drum trucks and trailers. I mix the trailer cement. we dont have any fancy machines or anything like that. we still use our brains, weights and scales. we do just about everyting right there in our own yard. we jack hammer our trucks, fix whatever breaks(except the things that we know nothing about or dont have the correct tool to fix) if you think this sounds like a dirty job let me know
