Smoothing out the Cement... with Lasers!

Once the cement is poured, it has to be spread out evenly and smoothed out.  Since we're going to be laying a gym floor on the cement surface, it's very important the floor be perfectly even, with no high points or dips.  We used another machine that uses a laser to ensure the cement is even to within one eighth of an inch over the entire surface.  The machine works kind of like a squeegee with a long arm that stretches out over the pile of cement and a blade that is pulled back across the cement to spread it out.  To see the machine in action, check out the youtube video here:
