Power plants & electrical facilities

Trenches, roofs, floors.
We protect the parts of a power plant that can’t stop.

Cable trenches and pits, substation roofs, control-room floors, powerhouse roofs and column repair: we choose the system that fits, then build it up in the right order, from substrate to top coat. When PASSAWARN installs, the manufacturer’s warranty applies.

Other methods

Protective coating for cable trenches and pits

Cable trenches, pits and tanks exposed to water, oil and chemicals are lined with a chemical-resistant film.

  1. Epoxy, coat 2Applied once the first coat has set; the two coats together build the specified thickness.
  2. Epoxy, coat 1The main protective film, resistant to chemicals.
  3. PrimerSoaks into the substrate so the next layer bonds.
  4. Concrete (ground and repaired)Weak surface ground off, cracks and voids filled to a sound, flat base.substrate

Layer thicknesses are exaggerated for clarity. Built up from the bottom.

When we install,
the manufacturer’s warranty applies.

Not just a contractor’s promise, but a promise from the technology owner. We deliver whatever brand the spec calls for.
