Conductive ESD flooring, Richardson, Texas
A classified Richardson room answers to two documents that never mention each other: a particle class and a resistance band. The record here shows semiconductor fab, telecom/data centers.
Richardson, and what gets built here
Fabrication and equipment work in Dallas County is what puts a resistance requirement on floors here, and each operation below carries the source it was checked against.
Texas Instruments received a $33.6 million Texas Semiconductor Innovation Fund grant tied
Texas Instruments received a $33.6 million Texas Semiconductor Innovation Fund grant tied to a roughly $700 million capital investment expanding capacity at RFAB, its 300mm wafer fab in Richardson.
Richardson's Telecom Corridor is home to 600+ technology companies
Richardson's Telecom Corridor is home to 600+ technology companies (AT&T, Ericsson, Samsung, Fujitsu among them), and Digital Realty operates its 69-acre "Digital Dallas" data campus in Richardson.
Two specs on one slab
A controlled room in Richardson has to hold its particle class and its resistance band at once, and the cleaning regime that protects the first is the usual way the second gets lost.
The document behind a Richardson job
ASTM F2170-19a is the one worth reading first for work like this. Determines relative humidity inside a concrete slab with in situ probes. This is the test a slab has to pass before an epoxy topcoat goes down.
Why moisture decides the job
Water vapour moving up through a slab pushes against the underside of a coating. If the slab is too wet when the system goes down, the floor can debond later regardless of how well it was installed. This is the single most common reason a resinous floor fails early.
Questions from Richardson
Our floor passed at install and fails now. What changed?
In a classified room the answer is usually something applied to the surface. Anything left on top of the system sits between the floor and its ground path. Check what the cleaning regime changed before assuming the floor wore out.
Can you look at our Richardson 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.
Is Richardson inside your normal service area?
Yes. Dallas County is covered on the regular Texas schedule, so a job here does not carry a travel premium the way a one off out of state trip would.

Crews working Richardson cover Plano, Garland, McKinney, Dallas on the same run, so a job in Dallas County rarely stands on its own.
