I'm learning a lot from you professionals

I'm learning a lot from you professionals. Thank you
for your knowledge.
I will need to stabilize and/or replace some "Moinkopi
Sandstone" in Holbrook Arizona on an old building.  Is
there any organization I could get in touch with that
could teach me what I need to know, or that could help
me with any testing that I would need to do?  I would
really appreciate any information you could give me.
