ISO-Rated Clean Room Flooring for Pittsburgh Facilities
Particle count, off-gas chemistry, and ESD grounding all depend on the floor. Pittsburgh Concrete installs seamless concrete systems engineered for ISO clean room certification, sealed-process zones, and battery production environments where surface contamination cannot be tolerated. We spec by class, prep in controlled conditions, install without seams, and verify particle and ESD performance before handoff.
Standard concrete sheds particles under foot traffic and equipment movement. In an ISO-rated clean room, that shedding eats into the particle budget the room is designed to maintain. A properly specified seamless floor system holds particles in place, contributes minimally to the room's contamination load, and lets the facility meet its ISO class target at commissioning.
We install smooth epoxy or urethane systems matched to your ISO class, with chemistry that does not off-gas at operating temperature and a grounding scheme for ESD-sensitive zones. The installation follows clean room discipline: controlled-environment prep, sealed transitions at every wall and penetration, post-cure particle and ESD verification.
We identify the target ISO class, the particle budget the floor contributes to, any ESD or grounding requirements, and the material chemistry that meets your process off-gas limits.
Prepare slab in controlled environment
The concrete slab is prepped using HEPA-filtered or contained methods to avoid cross-contamination, ground to the system profile, and any cracks filled with clean-room-rated repair materials.
Apply seamless coating system
The smooth seamless epoxy or urethane is applied without joints or seams across the room footprint, with the topcoat formulation that meets the particle-shed and off-gas specs.
Test and document results
After cure, particle count testing confirms the floor's contribution is within budget, ESD testing (where required) verifies the resistance range, and all certification documents are provided for commissioning.
Critical detail
How Sealed Transitions Protect Clean Room Integrity
The room footprint can be perfect, but the transitions are where clean room floors typically fail. Doorways, wall-floor junctions, pipe penetrations, and equipment pads all create seams where particles can escape or outside air can enter. We detail every transition with seamless cove, sealed penetrations, and integrated door frames so the floor's clean boundary holds across the entire room perimeter.
ISO class, particle budget, off-gas chemistry and transition details.
Multiple classes from less strict to more strict, with the floor system spec matched to the class. We confirm the target class up front and select the matched system; higher classes require lower-particulate materials and stricter install discipline.
Yes, significantly. A standard floor sheds particles continuously; a properly specified clean-room floor contributes far less. In an ISO-rated environment, every surface counts toward the particle budget.
Floor systems can off-gas trace chemistry that contaminates sensitive processes. We use chemistry rated for low off-gas in clean room applications, verified by the manufacturer for your specific class requirement.
Yes, transitions are where most clean room floors fail. We detail every transition (wall, door, penetration) with seamless cove and sealed integration so the floor's clean integrity holds at the room boundary.
Per room, typically a week or more depending on size and ISO class. The cure window before clean room commissioning adds additional time. The full schedule is in the quote and built around your commissioning calendar.
Client reviews
What Pittsburgh Operations Say About Their Clean Room Floors
ISO-class verified at commissioning with our floor as part of the particle budget. Hit class, room ran first try. The seamless transition detail at the door made the difference.

★★★★★
Off-gas verification on the floor chemistry for our sensitive process. No detectable contamination at the production analytical limit. Spec matched the process requirement exactly.

Process Engineer, Aliquippa
★★★★★
Multiple clean rooms across our facility, each at different ISO classes. They specced per room rather than one system everywhere; class targets hit in every room first commissioning.

Facility Engineer, Monroeville
★★★★★
Documentation package supported the validation file. Material specs, install method, particle verification all included. Auditor signed off without revisions.
