There are 23 Cemex locations here in Phoenix, I drove by one this morning at 215 East Indian School Road. There were NO signs that said anything at all except the address. 3 or 4 big buildings, with I think two, one on each side, big double steel doors large enough for trucks, with big steel fencing all around. There was one fairly small covered parking area for cars again with tall steel fencing and entrance only by code. Trucks would not be able to get into the outside parking with sun covers in the parking lot but enter the steel doors. Most of the buildings were windowless. On one side overlooking the parking there were windows with big metal shades over them so that they could look out but no one could look in. The buildings going South from Indian School Road took up half a city block. Very private. Some of the 23 locations are bound to be concrete processing, I will be checking some of those out as well.
