Epoxy Flooring System:

  • Solvent-free, low VOC high build epoxy coating.
  • Solvent-free, low VOC water-based epoxy floor coating.
  • Solvent-free, low VOC self-leveling epoxy floor finish.
  • Solvent-free, low VOC self-leveling anti-static / anti-spark epoxy floor finish.
  • Solvent-free, low VOC anti-slip / anti-skid epoxy floor finish.

Polyurethane flooring system:

  • Medium duty solvent-free, low VOC polyurethane-cement flooring.
  • Heavy-duty solvent-free, low VOC polyurethane-cement flooring.
  • Solvent-free, low VOC high flexibility, anti-skid polyurethane car park deck coating  – for intermediate decks.
  • Solvent-free, low VOC  high flexibility, waterproofing anti-skid polyurethane car park deck coating – for exterior roof, exposed car park floors.
  • Solvent-free, low VOC UV stable polyurethane floor coating.

Chemical Resistant Lining:

  • Chemical resistance, thermal resistance vinyl ester-based fiber glass lining (for wall and floor).
  • Chemical resistance, thermal resistance, anti-slip vinyl ester based floor coating.

In general terms, these categories of flooring are listed in ascending order of durability. However, the actual life in a particular installation will depend on the product formulation used, the quality of the substrate, and the degree of severity of the service conditions. Please refer to FeRFA “Guide to the Selection of Synthetic Resin Floors (ISBN 0 9538020 3 5) for further information on the features and characteristics of the floor types.

Concrete structural repair:

  • Chemical injection (epoxy and polyurethane) to crack sealing, leakage repairs.
  • Self-leveling cementitious grouting (for machine base, resurface unevenness, structural voids)
  • Pressure grouting – for pipe opening, ducting opening, lift core joints, structural retaining walls, basement structures etc.
  • Formwork grouting – column voids, cracks, basement wall structures, structural strengthening, beam joints, etc.
  • Joint sealing – non-movement joint and expansion joint sealing and repair works.
  • Diamond coring and sawing – for pipe opening, duct opening, structural opening, etc.
