With the basement cleaned out from the debris of the drywall phase we were finally able to book our crew to arrive on site for the slab finish we have selected. Similar to what you would see in a commercial building, but tweaked for a residential application, we will be grinding, pigmenting, treating and finally polishing the sealed slab. At this stage of the process the slab has been ground to flatten it, first with a 40 grit metal blade, and on to a 100 grid diamond bit sander. The large grinding machine and vacuum system have been extremely effective at keeping the dust down. The finished surface should be much more pleasant for walking on in winter when we have the heating system operational than a cold slab.
