ESD and Antistatic Flooring in Surrey
An electrostatic discharge event that causes no perceptible sensation to a person can permanently destroy a microelectronic component worth hundreds of pounds. In manufacturing and assembly environments handling sensitive electronics, the floor is the first line of defence against static build-up. A standard epoxy floor offers zero protection. We install Electrostatic Dissipative (ESD) and Conductive resin flooring systems that safely route static charge to earth, meeting IEC 61340 and BS EN 61340 standards. We work across Surrey's electronics and technology manufacturing sector, including business parks around Camberley and Farnham, as well as data centre fit-outs and pharmaceutical cleanroom installations.
A recent project at a PCB assembly facility near Camberley required a full ESD floor across 800 square metres of production space. The resistance values were specified at 1 x 10 to the power of 6 through to 1 x 10 to the power of 9 ohms to meet the client's ESD coordinator's programme. We installed the copper earthing grid, the conductive primer, and the ESD topcoat over three consecutive weekends to avoid production shutdowns. The floor passed post-installation resistance testing at every measurement point on the first test. That result requires no shortcuts: the copper grid continuity must be verified at every junction before a single drop of primer goes down.
ESD and Antistatic Flooring in Surrey Installation Process
Substrate Preparation to Fine Profile
ESD floors require a high-quality, smooth, contamination-free base. Any inconsistency in the substrate creates inconsistency in the conductivity of the finished floor. We diamond grind to CSP 2 to 3 and ensure the surface is completely clean and dry before any ESD components are installed.
Copper Earth Grid Installation
A grid of highly conductive copper tape is laid across the entire floor area at specified intervals, typically 1 to 2 metre grid spacing. Each copper strip is mechanically fixed and electrically connected to designated earth points within the building's earthing system. We test continuity at every junction before proceeding. The integrity of this grid determines the performance of the entire system.
Conductive Primer Application
A specialised carbon-rich black conductive primer is applied over the copper grid, bridging between the grid lines and distributing the charge-dissipating capacity evenly across the entire floor area. This primer must achieve a specific resistance value before the topcoat is applied. We measure and document this at this stage without exception.
ESD Topcoat Application
The specified ESD-formulated epoxy or polyurethane topcoat is applied in the required colour. This topcoat is formulated with a controlled carbon loading that achieves the target resistance range, either ESD dissipative at 10 to the 6th through 10 to the 9th ohms, or conductive at 10 to the 4th through 10 to the 6th ohms, while providing the durability and chemical resistance of a standard resin floor.
Post-Installation Resistance Testing and Certification
Once fully cured, the floor is tested at multiple points across the area using a calibrated resistance measurement instrument to IEC 61340 test methods. Test results are documented in a numbered certificate issued to the client, recording measured resistance values at each test location and confirming compliance with the specified resistance range.
Systems and Options
The correct system depends on the required electrical resistance range and the application:
- Electrostatic Dissipative (ESD) Flooring: Slowly and safely drains static charge from personnel to earth, preventing discharge events that could damage sensitive microelectronics. The slower drainage rate prevents a shock hazard for personnel. Standard for electronics assembly, PCB manufacturing, and semiconductor handling environments.
- Conductive Flooring: Drains static charge very rapidly to earth. Required in ATEX zones where flammable gases, vapours, or explosive dust are present. Rapid charge dissipation prevents the spark ignition events that could trigger an explosion. Also specified in operating theatres to protect sensitive medical equipment.

Who Is ESD and Antistatic Flooring in Surrey Suitable For?
ESD flooring is mandatory for electronics assembly facilities, PCB and semiconductor manufacturing, data centres, server room fit-outs, and pharmaceutical cleanrooms across Surrey. Business parks in Camberley and Farnham have a notable concentration of electronics manufacturing and technology businesses, and ESD floors are a routine specification in these environments. We also install for pharmaceutical companies in the Leatherhead and Epsom areas, where cleanroom flooring often needs to be simultaneously antistatic and antimicrobial.
Conductive flooring for ATEX-rated environments is a more specialist application, typically for chemical handling facilities, fuel storage and transfer areas, and explosive materials processing sites. These installations require close coordination with the client's ESD coordinator, safety officer, and often the site's insurance underwriter, as the resistance specification forms part of the site's ATEX risk management documentation. We have completed ATEX-rated conductive floor installations at chemical handling facilities in the Surrey area and are familiar with the documentation requirements that accompany these projects.
