Anti-Static / ESD Flooring – Conductive Epoxy Systems for Electronics, Data Centres, and Critical Operations.

Driven by the applicable standard for your environment. For ANSI/ESD S20.20 compliance (electronics manufacturing EPAs): static-dissipative (10⁶-10⁹ Ω) is the default. For Tier III/IV data centres: static-dissipative. For pharma and GMP cleanrooms: static-dissipative typically, conductive where process-specific. For ATEX zones and munitions handling: conductive (10⁴-10⁶ Ω). Anti-static (10⁹-10¹¹ Ω) is the lightest tier – suitable where some control is needed but full ESD compliance isn’t required. We confirm tier in writing during the survey based on your specific compliance framework.

That’s the entire point of the testing-and-certification stage. We test resistance to IEC 61340-4-1, ESD STM7.1, and STM97 protocols at handover, with multiple test points per zone, and issue a certificate of compliance with the results. The certificate forms part of the warranty pack and is sized to satisfy OEM electronics audits, pharma regulatory inspections, ATEX competent-person reviews, and data centre tier certification. If a specific audit body requires a particular testing protocol, flag it at survey stage and we align.

Adhesive-bonded copper tape is laid in a grid pattern on the prepared substrate before priming – typical spacing 2-3m for static-dissipative systems, tighter (1-2m) for conductive. The grid is encapsulated by the conductive primer and body coats; resistance from any surface point on the finished floor flows through the conductive system to the grid, then via earthing tails to your building earth bonding system. Multiple tails per zone provide redundancy. Earthing diagram included in handover pack.

Yes – that’s a core part of the brief. Live-environment phasing means isolating one zone (or one rack row) at a time, working around operational shifts, controlling dust and noise during substrate prep, and protecting adjacent live equipment with hoarding. Method statements include access control, dust suppression, and emergency stop protocols. We’ve supported this delivery model for data centre operators and pharma facilities running 24/7.

Properly installed conductive epoxy maintains resistance specification for 10-20 years under normal use. The conductivity comes from carbon or metallic additives dispersed through the resin; these don’t deplete with wear. Surface contamination (especially polishes, waxes, oily residues) can mask the conductivity – which is why we recommend a maintenance regime that avoids these. Periodic re-testing (typically annual or biennial) is standard FM practice and confirms the floor still meets spec.

Then it needs Concrete Resurfacing or Concrete Restoration before ESD goes down. ESD systems assume sound, level concrete substrate. We flag substrate condition at survey and quote a combined scope if substrate work is needed. The earthing grid and conductive layers depend on a stable, properly-prepared base; cutting corners here means failing resistance at handover testing.

Yes – manufacturer-formulated low-VOC ESD systems are available from Sika, BASF, Mapei, and Fosroc for cleanroom and pharma applications. The outgassing certificate is provided as part of the handover documentation pack, supporting cleanroom qualification (IQ/OQ) and GMP audit. Application protocols include extra ventilation and cure-time management to minimise residual outgassing.

Manufacturer product warranty: typically 10-15 years on cured ESD systems (period varies by system and exposure). Our written workmanship guarantee: typically 2 years on installation. Resistance certificate of compliance issued at handover with measured values at multiple test points. Combined warranty pack: batch records, earthing grid drawings, daily QC logs, resistance test results, datasheets, manufacturer paperwork. Audit-ready for QA, regulatory, and certification body review.
