Marty Walker, a professional cement worker, prepares the dining center floor. The work required to finish the floor takes approximately 15-20 passes of grinding and polishing for each square foot of cement. The first 9 passes of grinding require diamond pads that grind down the agregate so that 3/8 pebbles show on the floor. Each 12' by 12' cement section takes 30 minutes to complete one pass. Doing the math, Marty will spend hundreds of hours preparing the floor so that it is ready for campers and guests.
The maching in the background will be used during the final stages of floor preparation. It has a special cleaning and vacuuming component so that cement dust does is collected and not spread out throughout the building.
