The Challenge of Plant Room & Roof Containment
Building roofs, plant room floors, and containment bunding areas beneath cooling towers are highly vulnerable to catastrophic failure.
They are constantly subjected to stress that compromises structural materials:
- Environmental Stress: The coating must be flexible enough to withstand vibration and capable of enduring the harsh chemical attack and varying high or low pH levels present in this environment.
- Chemical Splash-Out: Cooling towers frequently splash and spray chemicals onto building roofs, plant room floors, and concrete pads. These highly corrosive water treatment chemicals cause pitting in concrete and corrosion in steel.
- Structural Damage: Damaged concrete allows water and chemical leaks to penetrate into adjoining rooms or building levels, while corroded steel roofs allow leaks into the building structure.
- Containment Failure: Bunded areas designed to hold chemicals can be damaged by the corrosive agents they are meant to contain, leading to regulatory failure.
Without adequate containment systems, structural materials rapidly degrade due to chemical attack and splash-out, risking uncontrolled leaks that compromise building integrity, necessitate costly structural remediation, and result in severe compliance breaches.
