A clean room floor cannot shed particles, cannot off-gas chemistry, and cannot disrupt the airflow patterns the room is designed around. Oshawa Concrete installs concrete floor systems engineered for ISO clean room environments and sealed-process zones, with the seamless install, low-particulate materials, and grounding scheme that clean room operations require. Every project starts with a free written estimate.
Clean rooms run by particle count. Every surface in the room contributes to or detracts from the particle budget. A standard concrete floor sheds microscopic particles continuously under traffic; a sealed clean room floor system holds those particles in place and lets the room maintain its ISO rating.
We install smooth seamless epoxy or urethane systems with the right surface finish for the ISO class, the chemistry that does not off-gas at room temperature, and the grounding scheme for any zones requiring ESD dissipation. The install protocol respects clean room construction discipline: HEPA-filtered prep where required, sealed transitions, post-install verification.
We confirm which ISO clean room class applies, the particle budget the floor contributes to, any ESD or grounding requirements, and the material chemistry that meets your facility's off-gas spec.
Prep slab in clean conditions
The slab is prepped using HEPA-filtered or contained-prep methods where required to avoid contaminating adjacent clean spaces, surface ground to the system's prep profile, and any cracks repaired with clean-room-compatible materials.
Install seamless system
The smooth seamless system is installed without seams or transitions in the room footprint, with the matched topcoat that meets the off-gas and particle-shed specs the room requires.
Verify and certify
After cure, particle count verification confirms the floor's contribution is within budget, ESD verification (where required) confirms the resistance range, and certification documentation is delivered for the clean room's commissioning.
Why details matter
Transitions Are Where Clean Rooms Fail
A clean room floor that is perfect across the room footprint can fail at the transitions, the doorway to a non-clean space, the wall-floor junction, the pipe penetrations. We detail every transition with seamless cove, sealed penetrations, and door-frame integration so the floor's clean integrity holds across the entire room boundary.
Coordinate with the rest of EV battery services in the facility and with adjacent ESD flooring in non-clean ESD-sensitive zones that share floor systems.
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 Oshawa 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.
Y. J5
Process Engineer, Toronto
★★★★★
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, Brampton
★★★★★
Documentation package supported the validation file. Material specs, install method, particle verification all included. Auditor signed off without revisions.
