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.
aviation support and maintenance
distribution and high bay warehousing
electronics and component handling
We work the whole airport corridor, from Thorn Run out through Findlay and Park West.
The standard
The two bands the standard defines
Measured to ANSI/ESD STM7.1. Which one 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
- Conductive2.5 x 104 to 1.0 x 106 ohmsCharge has to leave the floor fast.
- Static dissipative1.0 x 106 to 1.0 x 109 ohmsCharge bleeds off in a controlled way.
- Ordinary epoxyabove 1.0 x 1011 ohmsTwo decades past anything the standard accepts.
Conductive
2.5 x 10⁴ to 1.0 x 10⁶ ohms
Charge has to leave the floor fast and the operation handles parts that fail at low voltage. Common in electronics assembly and munitions or energetics work.
Static dissipative
greater than 1.0 x 10⁶ to less than 1.0 x 10⁹ ohms
Charge has to bleed off in a controlled way rather than dump. The usual choice where people work around live equipment and a hard path to ground is a shock risk.
The whole system
less than 1.0 x 10⁹ ohms
Floor, footwear and person together to ANSI/ESD STM97.1, plus a walking test 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.
Reading conditions over Moon Township...
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 six that come up once you have a slab and a deadline. The full twenty five, on resistance, grounding and test method, are on the Pittsburgh page.
Cost is driven by four things: square footage, how much existing coating has to come off, whether the slab needs moisture mitigation, and which band you have to hit. A grind-and-coat over sound concrete and a full mitigation build on a wet slab are different projects. We quote after we have seen the slab and know the band, not before.
Most plant floors run 3 to 5 days from grind to return to service, driven by square footage, how much coating has to come off first, and cure time between coats. A phased install keeps part of the floor working while the rest goes down.
Yes, in phases, nights and weekends. Most plants cannot give up a whole floor at once, so the floor gets sectioned and the grounding network gets tied together as the sections join.
Yes. Impact and abrasion are a separate spec from resistance, handled with a thicker build or a urethane cement body under the conductive topcoat. Ask for both numbers, because a floor can be compliant and still be too soft for your traffic.
Yes, across the Pittsburgh metro including Cranberry Township, Robinson Township, Moon Township, Monroeville, Warrendale, North Strabane Township and the surrounding Butler, Allegheny, Washington and Beaver county corridors.
Four things: square footage, the band you have to hit (conductive or dissipative, and whether an audit sets it), what is on the slab now, and your traffic. If you do not know the band, that is a normal place to start and it is worth settling before anyone quotes you.
