Seamless ISO Clean Room Flooring for Laval Facilities
Battery production and sealed-process manufacturing demand floors that do not shed particles, do not release chemical vapors, and do not interfere with the controlled airflow the room depends on. Laval Concrete pours and finishes seamless concrete systems engineered for ISO clean room specifications, with low-particulate materials, verified off-gas chemistry, and grounding where ESD control is required. Free written estimate on every project.
ISO clean room ratings depend on particle count per cubic meter. Every surface in the room contributes to or subtracts from that budget. Standard concrete sheds microscopic particles under foot traffic and equipment movement; a sealed seamless floor system traps those particles and keeps the room's ISO classification intact.
We specify smooth seamless epoxy or urethane systems matched to your ISO class, with chemistry that does not off-gas at operating temperature and grounding resistance for ESD-sensitive zones. The installation follows clean room protocols: contained prep work, HEPA filtration where needed, sealed transitions at walls and penetrations, and post-cure particle verification before handoff.
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 conditions
The concrete slab is prepped using contained or HEPA-filtered methods to avoid contaminating adjacent spaces, ground to the system profile, and any cracks filled with clean-room-rated repair materials.
Apply seamless system
The smooth seamless coating is applied without seams or joints across the room footprint, with the topcoat formulated to meet the off-gas and particle-shed specifications your process requires.
Test and document
After cure, particle count testing confirms the floor meets the ISO budget, ESD resistance is verified where required, and all certification documents are prepared for clean room commissioning.
Critical detail
Room Boundaries: Where Clean Room Floors Fail
The floor's seamless integrity fails at transitions. Doorways, wall-floor junctions, pipe penetrations, and equipment footings are where particle leakage occurs if not detailed correctly. We seal every transition with seamless cove, sealed penetrations, and integrated door frames so the floor's clean boundary holds across the entire room perimeter.
Coordinate with chemical-resistant flooring in adjacent production zones and with freezer floor systems if your facility includes temperature-controlled areas that share the clean room boundary.
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 Laval 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, Montreal
★★★★★
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.
Q. J5
Facility Engineer, Terrebonne
★★★★★
Documentation package supported the validation file. Material specs, install method, particle verification all included. Auditor signed off without revisions.
