San Antonio-New BraunfelsMedina County
Conductive ESD flooring, Castroville, Texas
Server halls, network operations space and dispatch floors in Castroville run on equipment that never powers down, so the hard part of a floor here is rarely the coating. It is finding the hours. The record for Castroville shows data centers.
The measured record for Castroville
The demand in Castroville comes from equipment density rather than population, and these are the operations behind it, each with the document it was verified against.
Castroville, west of San Antonio, has become a major data center cluster
Castroville, west of San Antonio, has become a major data center cluster: Microsoft's SAT82 project (filings of $482.6 million in July 2024 and $400 million in January 2026) is part of a cluster with over $2.19 billion in confirmed investment across approximately 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 106 to 1.0 x 109 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.

Crews working Castroville cover San Antonio, Austin, Baytown, Conroe on the same run, so a job in Medina County rarely stands on its own.
