Cincinnati Pharmaceutical Manufacturing Facility

Solving Cleanroom Wall Compliance Issues in FDA cGMP Facilities

When a pharmaceutical manufacturing facility in Cincinnati needed to upgrade approximately 1,200 SF of manufacturing suite walls that were failing cleanroom certification requirements, they faced a critical challenge: the existing concrete block construction with grout lines created sanitation issues and prevented the facility from meeting FDA cGMP standards for pharmaceutical production environments.

The Challenge

The pharmaceutical facility operates manufacturing suites requiring strict cleanliness standards and regulatory compliance for drug production. The manufacturing spaces featured concrete block walls with visible grout lines. These grout lines caused significant issues with both cleaning protocols and room certification for pharmaceutical manufacturing. The existing block walls with grout lines prevented the facility from achieving or maintaining these certifications, putting production operations at risk. In pharmaceutical production environments, every surface detail matters:

Regulatory & Certification Requirements

Pharmaceutical manufacturing facilities must meet stringent FDA requirements under 21 CFR Parts 210 & 211 (Current Good Manufacturing Practices):

Hardig's Approach

Rather than installing a weak drywall overlay system, Hardig proposed and executed a high-performance solution: resurfacing the existing concrete block walls using a specialized epoxy paste system with integrated fiberglass reinforcement, creating seamless, pharmaceutical-grade wall surfaces.

Fiberglass Reinforced Panel (FRP) System with Epoxy Paste

Hardig's solution involved resurfacing approximately 1,200 SF of concrete block using high-performance epoxy paste with an integrated fiberglass reinforcement system.

Pharmaceutical-Grade Surface Characteristics

The material chosen prevents particulate contamination, offers easy residue and contaminant removal due to its smooth, non-porous surface which facilitates FDA-required cleaning validation, and boasts a 20+ year lifespan under strict pharmaceutical cleaning protocols.

Integrated Urethane Floor Finishes

In addition to the wall system, Hardig installed urethane floor finishes in the manufacturing suites. This approach ensured the entire room envelope met pharmaceutical cleanroom standards with coordinated, compatible systems designed to work together.

Compliance with Pharmaceutical Standards

The completed wall system met: FDA 21 CFR 211.42 (smooth, hard, easily cleanable walls). FDA 21 CFR 211.58 (cleanable and sanitary condition). ISO 14644 cleanroom standards (non-shedding surfaces). ISPE (International Society for Pharmaceutical Engineering) baseline guides for facility design

The Results

The plant staff praised the cleanability and smoothness of the new wall finish. The FRP system made their sanitation processes significantly easier.

The wall upgrade brought the manufacturing suites up to pharmaceutical industry standards for cleanroom construction. The facility could now:

The seamless epoxy/fiberglass system completely eliminated the grout lines that previously harbored contaminants, prevented effective cleaning, and compromised cleanroom certification.
