Do you know what’s going on here? Post Tension or not?

 

     

Honestly I have no idea, it is stamped with Post Tension but there appears to be an expansion joint visible in both garages. There is also evidence of termites coming up the expansion joint. So I’m guessing but I think its a combination of Post Tension and Floating Slab.

What do I do? Do I drill the slab or not? Well if you hear screaming coming from Arizona it’s me!
