ESD & Conductive Flooring for Maine

General Dynamics Bath Iron Works (6,500-6,900 employees, Maine's 4th-largest private employer, lead shipyard for the Arleigh Burke-class DDG-51 destroyer program — building Flight III destroyers including DDG-126 Louis H. Wilson Jr. christened September 2025, DDG-148 honoring Cpl. Kyle Carpenter, plus DDGs 122, 124, 127, 130, 132, 134, 136, 138 under construction); Pratt & Whitney North Berwick Aero Systems (1,400 employees in the largest manufacturing facility under one roof in Maine — 1 million+ sq ft producing modules, components, and parts for commercial and military jet engines, 850 different part numbers across 30 engine sub-assemblies); Diodes Incorporated SPFAB at 333 Western Avenue South Portland (200mm analog wafer fab serving automotive and industrial semiconductor markets, formerly onsemi); IDEXX Laboratories Westbrook veterinary diagnostics; Kennebec Technologies Augusta precision machining; Tex Tech Industries specialty aerospace textiles; and the broad BIW supplier base across 15 of Maine's 16 counties.

Bath Iron Works is the lead shipyard for the Arleigh Burke-class (DDG-51) guided missile destroyer program — the longest-running surface combatant program in U.S. Navy history. Flight III destroyers are considered the most technologically advanced surface warships in the world, centered on an integrated air and missile defense radar system. Weapon systems integration, vertical launch system (VLS) installation, missile and torpedo handling, and propellant zones are arms, ammunition, and explosives (AA&E) operations governed by DoD Manual 4145.26-m, which requires combined floor + footwear + body resistance below 1.0 million ohms. PumaCRETE conductive (-c) systems achieve below 300,000 ohms on the floor alone — built-in factor of safety. The same product family handles dissipative ESD requirements for combat information center electronics, AN/SPY-6(V) radar component integration, and ship-system electronics throughout the DDG-51.

Jet engine manufacturing involves multiple ESD-sensitive operations: full authority digital engine control (FADEC) electronics, engine monitoring sensors, ignition systems, and engine health monitoring electronics — all governed by ANSI/ESD S20.20. The North Berwick facility produces 850 different part numbers and 30 engine sub-assemblies for commercial and military jet engines as an FAA 14 CFR part 120 regulated site. PumaESD dissipative epoxy systems achieve body voltage below 15 volts (versus the typical 100-volt aerospace ceiling) and integrate with the building grounding system per S20.20 across the 1 million+ sq ft facility. The seamless, monolithic surface also handles the daily wear of heavy industrial assembly fixtures, FOD (foreign object damage) prevention sweeping, and the precision metrology equipment used in engine component inspection.

EP Floors Corp. (Three Rivers, MA) is the PumaCRETE certified installer partner for Maine. North Berwick (Pratt & Whitney) is approximately 150 miles / 2.5 hours from Three Rivers via I-95 — comparable drive time to the New Hampshire seacoast. Bath (BIW) is approximately 175 miles / 3 hours. Southern Maine projects in Kittery, York, Wells, Saco, Biddeford, and Portland route closer. EP Floors has supported Maine defense, aerospace, and semiconductor facilities for decades. We do not sub-contract to unknown crews. Every installation is backed by a manufacturer-plus-installer warranty.

Static dissipative (SD) flooring has resistance between 1×10&sup6; and 1×10&sup9; ohms — for electronics, semiconductor, jet engine assembly, and biotech work where the goal is bleeding off static to protect ESD-sensitive components. Used at Pratt & Whitney North Berwick engine assembly, Diodes SPFAB wafer manufacturing, IDEXX Westbrook diagnostics instrument assembly, and BIW combat systems integration areas. Conductive (C) flooring has lower resistance (25,000 to 1.0 million ohms) — for AA&E, propellant handling, and weapons integration where the goal is ignition prevention. Used at BIW VLS installation zones, missile handling areas, and propellant work. PumaCRETE manufactures both ranges in one product family.

Yes. The South Portland SPFAB (formerly onsemi, acquired by Diodes Incorporated in 2022) produces 200mm wafers of analog semiconductors for automotive and industrial end markets. Semiconductor cleanrooms operate at ISO Class 5/6/7 — a thousand times cleaner than an operating room — with body voltage thresholds that demand dissipative ESD flooring below 100 volts. PumaESD 200 hi-build (30-60 mils) and PumaESD 301 composite (1/16 to 1/8 inch) systems meet these requirements with body voltage below 15 volts. The seamless, monolithic, low-VOC formulation supports cleanroom gowning protocols, HEPA filtration, and the daily IPA wipe-down typical of fab operations.

Yes. PumaCRETE offers three buying options: complete turnkey installation through EP Floors Corp. and other certified applicators, materials-only supply with detailed installation instructions, videos, specialty tools, and surface prep guidelines for in-house contractors or maintenance crews, or on-site factory training to qualify your facility's own team. Bath Iron Works has its own facilities maintenance organization for ongoing shipyard repairs. Pratt & Whitney North Berwick has in-house maintenance staff. The materials-only and training options work well for ongoing touch-ups in these large facilities — and you keep the full manufacturer warranty.

Yes. Beyond new construction at BIW, PumaCRETE serves Portsmouth Naval Shipyard (Kittery ME, though technically a federal installation straddling the NH-ME state line) for submarine overhaul, refueling, and modernization work. PumaCRETE conductive systems handle the AA&E and propellant zones during overhaul, while dissipative systems serve combat systems and electronics maintenance bays. The 25 lb moisture vapor handling capability of PumaCRETE 200 Series is particularly valuable for shipyard concrete substrates near tidal water with elevated baseline moisture transmission.
