Particle control starts at the floor. A sealed concrete floor system engineered for ISO clean rooms stops shedding, eliminates off-gas contamination, and maintains the airflow patterns your process depends on. Abbotsford Concrete installs seamless, low-particulate flooring with grounding where required, backed by material verification and post-install particle testing. Free written estimate on every project.
Why Sealed Concrete Flooring Matters in Clean Rooms
ISO clean room ratings depend on particle count per cubic meter. Every surface in the room contributes to that budget. An unsealed concrete slab sheds particles under foot traffic and equipment movement; a sealed floor system holds those particles in place and lets the room maintain its ISO classification without constant air-handling compensation.
We specify smooth seamless epoxy or urethane systems matched to your ISO class, with chemistry that does not off-gas at operating temperature. The installation follows clean room discipline: contained prep to avoid cross-contamination, sealed transitions at walls and penetrations, and post-cure particle verification to confirm the floor's contribution is within your budget.
Our ESD flooring work in adjacent zones coordinates with clean room boundaries. We also handle ready mix concrete supply for any structural pours, and concrete pumping for large-scale facility work.

Installation sequence
How Clean Room Flooring Gets Installed in Abbotsford
Specify ISO class and material
We identify the target ISO class, the particle budget the floor must meet, any ESD requirements, and the low-off-gas chemistry your process specifies. Material selection is confirmed in writing before prep begins.
Prep slab under controlled conditions
The concrete slab is prepped using HEPA-filtered or isolated methods to prevent contamination of adjacent spaces. Surface is ground to the system profile, cracks are sealed with clean-room-compatible repair materials.
Apply seamless floor system
Epoxy or urethane is applied as a seamless monolithic layer across the room footprint, with no seams or transitions in the active area. Topcoat is selected for the particle-shed and off-gas specs your process requires.
Test and document
After cure, particle count is verified to confirm the floor meets budget. ESD resistance is tested where required. Full documentation package supports your clean room commissioning and validation file.
Critical detail
Room Boundaries: Where Sealed Floors Fail
A perfect seamless floor across the room can fail at the edges. Transitions to non-clean spaces, door frames, wall-floor junctions, and pipe penetrations are where particle leakage occurs. We detail every transition with seamless cove base, sealed penetrations, and integrated door frames so the floor's integrity holds at the 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 Abbotsford 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.
Y. J5
Process Engineer, Chilliwack
★★★★★
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, Mission
★★★★★
Documentation package supported the validation file. Material specs, install method, particle verification all included. Auditor signed off without revisions.
