Pollutant Zones

Pollutant Zones

1. Introduction

Pollutant-heavy industries like refineries, fertilizer plants, chemical units face aggressive effluents, thermal stress, abrasion, and mechanical wear. Waterproofing must resist chemical attack and ensure long service life.

2. Exposures

  • Continuous chemical spills.
  • Abrasion & mechanical wear.
  • Thermal cycling (hot effluents, plant heat).
  • Long-term ponding or immersion.

3. Recommended Technologies

  • Polyurea Spray Membranes → top-tier, high chemical & abrasion resistance.
  • Epoxy-Polyurethane Hybrids (EPU) → chemical resistant coatings, industrial tanks.
  • Coal Tar Epoxy → used in refurbishments, legacy solution.
