Allegheny County, airport corridor
ESD Flooring in Moon Township
Static control floors for Moon Township operations, built to the band your process requires rather than to a colour chart.
What it is
Why Moon Township needs it
The airport corridor is high bay space, and high bay space brings its own conflict. Static control wants a specific conductive build. Forklifts, pallet jacks and rack loading want impact and abrasion resistance. Those are two different specifications and a floor has to satisfy both.
It is a solvable conflict and it is worth naming out loud, because a floor can be perfectly compliant and still be too soft for what runs across it. Ask for both numbers, not one.

The bonding plan
Every ground point, strip and termination gets drawn before anything is poured, because a floor that measures right in one bay and fails in the next is a bonding problem.
Where we work
The Moon Township corridor
We cover the Pittsburgh International Airport corridor along Interstate 376, Park West Industrial Park in Findlay Township, and the Thorn Run and Moon Township business parks.

electronics and component handling
We work the whole airport corridor, from Thorn Run out through Findlay and Park West.
The standard
Built to ANSI/ESD S20.20
Measured to ANSI/ESD STM7.1. Which band you need is set by what you build, never by preference.
ohms, logarithmic
S20.20 system ceiling, 109 ohmsfloor plus footwear plus person, to STM97.1
- Conductiveless than 1.0 x 106 ohmsCharge has to leave the floor fast.
- Static dissipative1.0 x 106 up to less than 1.0 x 109 ohmsCharge bleeds off in a controlled way.
- Ordinary epoxyfar above 1.0 x 109 ohmsHolds charge instead of moving it to ground.
The whole system has to measure under less than 1.0 x 10⁹ ohms to ANSI/ESD STM97.1, and a person walking on it has to stay under less than 100 volts peak to ANSI/ESD STM97.2.
Before anybody quotes
What we look at first on a floor like yours
What runs across it, and how heavy
Impact and abrasion are a separate spec from resistance. Heavy traffic usually means a thicker build or a urethane cement body under the conductive topcoat, rather than a coating alone.
Whether the slab is dry
ASTM F1869 or ASTM F2170 before anything goes down. Moisture coming up through a slab is the single most common reason a coating lets go, and you cannot see it standing on the floor.
How much coating has to come off first
Diamond grinding to a CSP 2 to 3 profile in almost every case, not acid etching and not a light scuff. In a building that has been recoated twice already, the removal is often the bigger half of the job.

STM7.1 reaches the floor, and stops there.
STM97.1 and 97.2 reach all four links.
STM97.1 under 1 x 109 ohms, and STM97.2 under 100 volts walking
That is the whole chain, measured together. The floor on its own never settles it.
ANSI/ESD S20.20
The ESD control program standard an audited facility is held to.
ANSI/ESD STM7.1
How the resistance of the floor itself gets measured.
ANSI/ESD STM97.1
How the floor, the footwear and the person get measured as one system.
ANSI/ESD STM97.2
The walking test. Peak body voltage a person generates on that system.
ASTM D257
The general DC resistance method the flooring methods descend from.
NFPA 77
Recommended practice on static electricity where ignition is the risk, not part damage.

Scheduling
Can you pour it in Moon Township this week?
Live air and dew point over Pittsburgh International Airport corridor along Interstate 376, Park West Industrial Park in Findlay Township, and the Thorn Run and Moon Township business parks, scored against ASTM D3276. Five degrees of margin over the dew point, held through prep, application and cure, or the floor blushes while it is going off.

What this is and is not
This reads the air. The standard governs the slab, and concrete lags air by hours, sometimes by most of a day after a cold night. A slab can still be under the dew point while the air above it looks fine. So treat this as your scheduling answer, not your go-ahead: the go-ahead comes off a surface thermometer and a hygrometer at the door on the morning of. Cure windows also move by system, so the product data sheet on your job is what governs.
FAQ
Static control questions
The three that come up first on a Moon Township floor. The full twenty five, on resistance, grounding and test method, are on the Pittsburgh page.
Yes, but they are two different specifications. Impact and abrasion resistance is separate from the resistance number, and a high bay floor in the airport corridor usually needs a thicker build or a urethane cement body under the conductive topcoat to take rack loading without going soft.
Yes, always. ASTM F1869 or ASTM F2170 first. Moisture coming up through a slab is the single most common reason a coating lets go, and standing on the floor will not tell you it is there.
Almost always down to a CSP 2 to 3 profile with diamond grinding, not acid etching and not a light scuff. In a building that has already been recoated once or twice, which describes a lot of the older airport corridor stock, removal is often the bigger half of the job.
