Expert Tank Maintenance Services

Tank maintenance encompasses preventive inspections, cleaning, corrosion monitoring, structural assessments, and protective coating applications designed to extend service life and prevent failures. At AmTech, comprehensive maintenance includes ultrasonic thickness testing to detect wall thinning, interior and exterior visual inspections for corrosion or damage, cleaning to remove sediment and contaminants, application or renewal of protective lining systems like HydraStone® or DuraChem®, and documentation for regulatory compliance. Proper maintenance transforms tanks into decades-long assets rather than liabilities requiring costly replacement.

Water storage tanks should undergo professional inspection and maintenance every 3-5 years at minimum, with high-usage or critical systems requiring annual assessments. AmTech recommends more frequent inspections for tanks over 20 years old, those showing previous corrosion issues, or systems storing treated water with aggressive chemistry. Maintenance schedules should align with API 653 standards for steel tanks and include ultrasonic testing, interior lining condition assessment, and water quality verification. Facilities serving hospitals, schools, or municipalities may require annual inspections to maintain compliance and ensure public health protection.

Key warning signs include visible rust or corrosion on exterior surfaces, water quality changes such as discoloration or metallic taste, unexplained water loss indicating leaks, peeling or blistering of existing coatings, structural issues like bulging or deformation, and difficulty maintaining proper system pressure. Interior indicators include sediment buildup, biological growth, pitting on steel surfaces, or failed lining systems showing bare substrate exposure. Any of these conditions warrant immediate professional assessment to prevent catastrophic failure and costly emergency repairs.

Maintenance duration varies by tank size, condition, and scope of work required. Routine inspections and ultrasonic testing typically require 4-8 hours. Basic cleaning and minor repairs may take 1-3 days. Comprehensive maintenance including surface preparation and protective lining application ranges from 5-10 days for smaller tanks to several weeks for large industrial storage systems. AmTech's DuraChem® 500 series instant-cure technology significantly reduces downtime compared to traditional multi-coat epoxy systems that require extended cure periods between applications.

Tank maintenance costs depend on tank size, material, condition, access requirements, and scope of services needed. Routine inspection and cleaning may range from $2,000-$5,000 for smaller commercial tanks. Comprehensive maintenance including surface preparation, structural repairs, and protective lining application typically ranges from $8,000-$25,000 for mid-sized tanks, with larger industrial systems requiring $50,000-$150,000+ investment. However, proactive maintenance costs a fraction of emergency repairs or full replacement—often saving facility owners tens of thousands in capital expenditures while extending useful life by 20-30 years.

Most comprehensive maintenance services require complete tank drainage to ensure proper inspection, cleaning, surface preparation, and lining application. However, AmTech offers specialized services for situations where full drainage is impractical, including external ultrasonic testing to assess wall thickness from outside, underwater inspection using remotely operated equipment for preliminary assessment, and emergency repairs using specialized sealants for temporary leak mitigation. For optimal results and long-term protection, we recommend coordinating maintenance during planned facility shutdowns when full drainage and interior access is possible.

Yes, AmTech maintains rapid-response capabilities for critical tank failures requiring immediate attention. Our engineer-led field crews mobilize quickly across the US and Canada with proprietary repair materials including DuraChem® instant-cure polylinings, HydraStone® cement systems, fiberglass laminate materials, and PLS 755 Tank Tape for temporary leak sealing. Emergency services cover active leaks, sudden corrosion breakthroughs, lining failures, structural cracks, and regulatory shutdown scenarios. We prioritize minimizing facility downtime and preventing environmental incidents, with crews strategically positioned nationwide to ensure rapid deployment when every hour counts.

AmTech maintains comprehensive industry certifications including ANSI compliance, NSF compliance for potable water systems, NLPA compliance with Special Inspector credentials, API compliance for petroleum storage tanks, UL listed lining systems, and OSHA 10/30 safety certifications for all field personnel. Our teams are trained in API 653 tank inspection and repair standards, SSPC surface preparation protocols, and NACE corrosion control methodologies. We hold Thomas Verified accreditation and NFPA membership, ensuring all maintenance work meets or exceeds national standards for safety, quality, and regulatory compliance across water, wastewater, chemical, and petroleum applications.
