AmTech delivers comprehensive welding and tanker repair solutions for industrial, commercial, and municipal storage tanks. With over 55 years of proven expertise, we restore structural integrity, eliminate leaks, and extend tank service life using proprietary materials and engineer-led field crews.
Comprehensive structural repair, leak remediation, and emergency restoration services for all tank types and materials.
API 653-compliant steel repairs including patch welding, bottom replacement, corroded section removal, and nozzle attachment. Performed on petroleum, chemical, and water storage tanks to restore structural integrity and prevent catastrophic failure.
Rapid-response mobilization for active tank leaks, corrosion breakthroughs, and structural failures. On-site assessment, temporary containment, and permanent repair using proprietary materials to minimize downtime and prevent environmental incidents.
Laminate buildup and reconstruction using custom-assembled glass, Kevlar, or carbon veils with polyester, vinylester, or epoxy resins. Repairs cracks, delamination, blistering, and chemical attack in FRP tanks.
Welding of code-compliant 22-inch manways with 18-bolt covers onto existing single or double-wall steel tanks. Provides human access for inspection, cleaning, lining, and maintenance to extend tank life and meet regulatory requirements.
API 653 bottom repair including ultrasonic thickness testing, corroded steel cutout, new steel welding, and installation of FRP or DuraChem® 500 floor pan barrier. Protects against underside corrosion and stored product attack.
Removal and replacement of damaged, cracked, or leaking tank nozzles. Steel nozzle welding for ASTs and fiberglass nozzle laminate rebuild for FRP tanks, restoring proper tank-to-nozzle bonding and eliminating leak points.
When storage tanks experience corrosion, leaks, or structural damage, AmTech's certified welders and field engineers deliver permanent solutions that meet API, NFPA, and OSHA standards. Our proprietary repair materials—including instant-cure DuraChem® polylinings, fiberglass laminate systems, and welding-grade steel—are selected based on tank material, stored substance, and operating conditions. Every repair is backed by ultrasonic testing, structural assessment, and our industry-leading BLUE CHECK warranty program.
Trusted by Fortune 500 companies, municipalities, and DOD facilities nationwide for mission-critical tank repairs.
Over five decades of proven expertise in welding and tanker repair services.
Experienced crews stationed across North America mobilize quickly with repair materials on hand to minimize facility downtime and prevent environmental incidents.
All structural repairs meet API Standard 653 requirements. Crews hold OSHA 10/30 certifications and comply with NLPA, ANSI, and NSF standards for safety and quality.
Projects are supervised by field engineers and NLPA Special Inspectors who assess damage, specify repair methods, and verify integrity using ultrasonic and NDT testing.
Exclusive access to DuraChem® instant-cure polylinings, HydraStone® Alkrete cementitious systems, and custom-assembled fiberglass laminates engineered for extreme service conditions.
Engineer-trained professionals with decades of field experience.
