Particle-Verified Clean Room Concrete Flooring in Boston
ISO clean rooms live or fail on particle count. The floor is part of that budget. We install seamless epoxy and urethane systems engineered to shed zero particles, off-gas nothing, and ground ESD where the process demands it. Spec, prep, install, verify, certify. Free written estimate.
Standard concrete floors shed particles under foot traffic, equipment movement, and air circulation. In an ISO-rated clean room, that shedding eats into your particle budget and can push the room out of spec. A properly engineered seamless floor holds particles in place, contributes minimally to the count, and lets the room maintain its ISO class through production cycles.
We specify epoxy or urethane systems matched to your ISO class, with chemistry that does not off-gas at operating temperature and a surface finish that resists particle generation. The install follows clean room discipline: contained prep, HEPA filtration where needed, sealed transitions, and post-cure verification of particle count and ESD resistance.
We identify the target ISO class, the particle budget the floor must meet, any ESD or grounding requirements, and the off-gas chemistry limits for your process. Material selection is locked to the class.
Prepare slab in controlled conditions
The concrete slab is prepped using HEPA-filtered or sealed methods to avoid contaminating adjacent spaces. Surface is ground to the system profile, cracks repaired with clean-room-rated materials, and dust removed.
Apply seamless epoxy or urethane
The seamless system is applied without joints or seams across the room footprint. Topcoat is selected for the particle-shed and off-gas specs your process requires.
Verify particle count and ESD
After cure, particle count is measured to confirm the floor meets budget. ESD resistance is tested where required. Certification documentation is delivered for clean room commissioning and validation files.
Critical detail
Room Boundaries: Where Clean Room Floors Fail Most
The floor-to-wall junction, doorway transitions, and pipe penetrations are where clean room integrity breaks. We detail every boundary with seamless cove base, sealed penetrations, and door-frame integration so the floor's particle containment 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.

What Boston Facilities 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, Cambridge
★★★★★
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, Somerville
★★★★★
Documentation package supported the validation file. Material specs, install method, particle verification all included. Auditor signed off without revisions.
