Cooling Tower Basin Repair

Long-lasting repairs | In-situ leak sealing available | Fraction of replacement cost

Leaking cooling tower basins don’t have to mean costly replacement or extended downtime. Banks Industrial Group (BIG) provides rapid repair and protective coating of deteriorated basins, sumps, and drain pans—completed rapidly during planned shutdowns or unplanned outages caused by active leaks. Using advanced Belzona polymer systems, we rebuild metal and concrete, seal leaks, and apply long-term protection against corrosion and chemical attack. Emergency in-service leak sealing is also available when immediate action is required. Serving the Mid-Atlantic and Northeast, BIG helps contractors and facility teams restore reliability—fast.

Emergency Cooling Tower Leak Sealing

When a leak is actively causing damage—especially from rooftop equipment—BIG can respond quickly to stabilize the situation. Our surface-tolerant repair materials bond to wet substrates and cure rapidly, allowing in-service leak sealing until full basin restoration can be completed during shutdown.

What starts as a small basin leak can lead to:

  • Interior water damage and costly repairs
  • Safety hazards for personnel and occupants
  • Disruption to operations or tenant spaces
  • Emergency shutdowns during peak demand

Fan Blade & Shaft Repair Services

BIG also restores cooling tower fan blades and fan shafts using fast-curing repair materials. Rebuild worn shafts, repair eroded blade edges, reduce vibration, and restore efficiency—helping you avoid replacement delays and return to service faster.
