Clean Room Flooring Case Study: Warehouse Floor Conversion for Medical Device Manufacturing

Project Overview

A medical device manufacturer needed to convert an existing warehouse area into a clean room production environment. The challenge was not simply installing a floor coating—it required creating a durable, contamination-conscious flooring system capable of supporting manufacturing operations while meeting strict safety and cleanliness standards.

With tight construction timelines and no margin for failure, the project required coordination between the general contractor, clean room specialists, coating manufacturers, and Durable Surfaces to deliver a resilient floor built for long-term performance.

The Challenge: Converting Warehouse Flooring into a Clean Room Environment

The existing concrete slab presented multiple concerns that threatened long-term clean room performance:

• Elevated moisture levels within the concrete
• Areas of delamination and joint spalling requiring repair
• Existing slab movement that risked crack transfer through future coatings
• Aggressive construction schedules with minimal room for delays
• Specialized safety requirements for personnel wearing protective fabric booties

Traditional anti-slip floor systems were not an option because abrasive aggregate could contribute fabric shedding and contamination risks inside the manufacturing environment.

Even more concerning, prior flooring systems had failed when cracks transferred through coating systems. Any future coating failure could force clean room shutdowns, creating significant operational and financial consequences.

Concrete Floor Repair and Surface Preparation

Durable Surfaces developed a flooring system engineered specifically for clean room performance, durability, and long-term protection.

The solution focused on three priorities:

1. Moisture and Bond Protection

To prevent coating failures caused by moisture migration, crews installed a moisture vapor primer (MVP) system designed to reduce the risk of delamination.

2. Crack Mitigation and Structural Protection

Control joints and construction joints were reinforced using:

• 12″ fiberglass chop strand mat saturated with flexible epoxy
• Flexible epoxy treatments designed to reduce crack transfer
• A 40-mil flexible epoxy protection layer to accommodate movement

This system helped protect the finished surface from future slab movement.

3. Clean Room Safety and Performance

To satisfy slip resistance requirements without creating contamination concerns, Durable Surfaces designed an orange peel texture finish that:

• Improved slip resistance
• Eliminated the need for traditional anti-skid aggregate
• Reduced contamination concerns associated with protective footwear

The final flooring assembly incorporated a 3/16″ self-leveling epoxy system designed to achieve the specified durability and resilience requirements while meeting clean room performance expectations.

Installing a Clean Room Epoxy Flooring System

Durable Surfaces began work immediately upon arrival to maintain the aggressive construction schedule.

Inspection and Evaluation

The team conducted:

• Relative humidity testing using Wagner L6 probes
• Surface evaluations to identify delamination
• Joint assessments
• Repair planning to minimize construction impacts

Surface Preparation

Crews prepared the slab through:

• Shot blasting using Blastrac equipment
• Edge preparation using Hilti hand tooling
• Crack repair
• Spall repair
• Delamination repair using epoxy mortar systems

Surface preparation established the proper concrete surface profile (CSP) required for long-term coating performance.

Installation

The flooring system was installed in phases:

1. Moisture vapor primer application
2. Joint reinforcement and crack mitigation systems
3. Flexible epoxy installation
4. Self-leveling epoxy placement
5. Cove base coating and sealing

Every component was selected to improve durability while supporting the cleanliness and operational requirements of the manufacturing environment.

Results: Durable, Safe Manufacturing Flooring Built for Performance

Durable Surfaces delivered a technical flooring system designed to support clean room manufacturing requirements while minimizing long-term operational risk.

The finished floor provided:

• Enhanced durability
• Improved crack resistance
• Moisture protection
• Clean room-compatible slip resistance
• Long-term coating resilience
• Reduced risk of production disruption

Most importantly, the manufacturer gained a flooring system engineered not simply to look clean, but to perform reliably in a high-demand production environment where downtime was not an option.
