NSF-61, AWWA, API tank linings
Tank Lining & Coating
Tank linings are zero-defect work. A pinhole in a potable water tank lining costs more than the original coat. Our network includes NACE-certified inspectors and SSPC-QP-3 shop applicators who line steel and concrete tanks per AWWA D102, NSF/ANSI 61, and API 652 specs, with full QA documentation and holiday testing.
Common applications
Frequently asked
How much does it cost to line a tank?
Interior tank lining typically runs $8–$25/sq ft of internal surface, including blast prep, primer, intermediate, topcoat, and holiday testing. A 100,000-gallon potable water tank is usually $35,000–$120,000 lined.
Do you do NSF-61 potable water linings?
Yes — every applicator in the tank lining network carries NSF/ANSI 61 certification for potable water and SSPC-QP-1 or QP-3 shop/field qualification.
How long does a tank lining last?
100% solids epoxy potable water linings: 15–20 years. Novolac epoxy chemical linings: 10–15 years. Coal tar epoxy on wastewater: 20+ years. We provide manufacturer warranty docs with every job.
Can you do confined-space tank entry?
Yes — all field crews are OSHA confined-space and rescue trained, with attendant, ventilation, and gas monitoring on every interior tank job.
