Method · Flooring
For data centres and electronics production, where static can damage equipment. Before handover we measure the floor's resistance.
An epoxy floor made to carry static away, laid over a copper-tape grid that is connected to the building earth.
Data centres and electronics production, where static can damage equipment.
Before handover the floor's resistance to ground is measured to be below 1×10⁹ Ω (ANSI/ESD S20.20) or the project's specified range. ESD floors work together with the footwear.
Layers (built up from the bottom)
A self-levelling conductive finish that flows out flat.
Applied over the copper tape. It carries static to the tape.
Laid in a grid on the primer and connected to the building’s ground.
Soaks into the concrete so the next layer bonds.
Weak surface ground off, cracks and voids filled to a sound, flat base.
The figure shows one typical build-up. The actual layers are decided after we see the site.
Slab moisture is always measured before a resin floor; damp slabs need a moisture barrier or a moisture-tolerant system.
Floors are chosen by how they are used. If another floor fits better, we will say so.
| Floor | Strength | Where |
|---|---|---|
| Epoxy | Smooth seamless floor, easy to clean | Indoor factory, showroom, lab |
| Epoxy ESDthis page | Drains static to earth through a grounded layer | Data center, electronics |
| Polyurethane (PU) Coating | Flexes; outdoors with a UV-stable top coat | Outdoor, moving substrates |
| PU Cement (PU + cement) | Thick & tough, survives sudden hot/cold + hot-wash | Food, cold storage, pharma |
| Polyurea | Sets in seconds, extremely tough | Extra-high durability areas |
| PMMA | Fast cure — the floor reopens the same day | Car park deck, floors that must reopen fast |
| STPE | Goes down on damp (not wet) slabs | Basin floors, enclosed damp areas, high-moisture slabs |
| FRP Lining (resin + glass fiber) | For severe chemicals, mainly strong acids | Treatment & chemical floors |
The floor area, the state of the substrate (whether cracks, chips or moisture need repair first), the type and build of the finish, the chemicals and traffic it must take, and the hours we can work. Send photos and drawings on LINE and we will check the site and quote.
The epoxy is made to carry static and laid over a copper-tape grid connected to the building earth, so static drains away. The resistance is measured before handover (below 1×10⁹ Ω to ground, ANSI/ESD S20.20).
A damp slab needs a moisture barrier or a moisture-tolerant system. For high-moisture slabs and enclosed damp areas there is STPE, which goes onto damp (not wet) slabs, often with no primer. We measure the moisture before we choose.
Send the area, how the floor is used and a few photos. We check the site and propose the floor that fits.
