Floor Grinding

This grage floor had low spots (Birdbaths) in it that pooled water when a wet, snowey vehicle was brought inside.  After a few hours with my 13hp Core Cut Grinder the low spots were sloped to the floor drain. 

There was also a 2 1/2" lip by the apron (photo "B") that made accessing the garage difficult.  I ground that down for a smooth transition.
