Conductive ESD flooring, Castroville, Texas

Castroville, west of San Antonio, has become a major data center cluster: Microsoft's SAT8
Castroville, west of San Antonio, has become a major data center cluster: Microsoft's SAT82 project (two filings totaling roughly $400-482 million) and CyrusOne's SAT14A (460,000 sq ft, ~$500 million) are part of a cluster with over $2.19 billion in confirmed investment across six buildings and four addresses as of April 2026.
Uptime is the constraint
A room full of energized racks changes two things about a Castroville job. The resistance band is often set higher for the safety of the people working around live power, and the schedule stops being a detail and becomes the whole plan.
The document behind a Castroville job
ANSI/ESD STM97.1-2025 is the one worth reading first for work like this. System resistance measurement of a person, their footwear and the floor as one circuit. This is the test behind the S20.20 ceiling.
A 2025 edition, replacing 2015
The current edition is 2025 and it supersedes the 2015 one. If your program document cites the 2015 edition it is not wrong, it is simply on an older revision, and it is worth checking what changed before your next audit.
Questions from Castroville
Does a Castroville data hall need conductive or dissipative?
Your program document decides, and rooms with energized equipment often sit higher rather than lower. FAA-STD-019 specifies 1.0 x 10^6 to 1.0 x 10^9 ohms in rooms with live equipment for personnel safety[11], which is above a typical manufacturing floor.
Do you handle the whole job in Castroville or just the coating?
The whole job: removing what is down, preparing the slab, the grounding network, the system itself and the cure schedule around your operation. Prep and grounding are where most of the work is. How it runs.
Can you look at our Castroville floor before we commit to anything?
Yes, and for an existing floor that is the sensible first step. Measuring what you already have against your requirement often costs a fraction of replacing it, and plenty of floors pass. What pushes a floor out of range.
