Expert Welding & Tanker Repair Services

AmTech repairs all tank types including above-ground atmospheric storage tanks (ASTs), underground storage tanks (USTs), and process tanks constructed from steel, fiberglass, FRP, concrete, or laminate. Repairs cover petroleum storage tanks (crude oil, diesel, gasoline, jet fuel), chemical storage tanks, potable water tanks, hot water tanks, wastewater tanks, and fire suppression tanks. All welding work is performed by certified welders following API Standard 653 guidelines for structural integrity and safety compliance.

AmTech provides rapid emergency response with experienced field crews stationed throughout the United States and Canada. When a facility reports an active leak, corrosion breakthrough, nozzle blowout, or structural crack, crews mobilize as quickly as possible—often within hours—carrying proprietary repair materials including instant-cure DuraChem® polylinings, fiberglass laminates, PLS 755 Tank Tape, and welding equipment. The goal is to provide temporary containment, assess damage, and execute permanent repairs to minimize downtime and prevent regulatory violations or environmental incidents.

Yes. All AmTech welding and structural repairs meet or exceed API Standard 653 (Tank Inspection, Repair, Alteration, and Reconstruction), NFPA fire protection standards, OSHA safety requirements, and applicable state and local regulations. Field crews hold OSHA 10 and OSHA 30 certifications, and projects are supervised by field engineers and NLPA Special Inspectors who verify compliance through ultrasonic testing, visual inspection, and non-destructive testing (NDT) methods. AmTech is also ANSI compliant, NSF compliant, and a Thomas Verified company.

Tank bottom repair begins with ultrasonic thickness testing to map corrosion and identify perforated areas. Corroded or damaged steel sections are cut out and new steel is welded in according to API 653 specifications. The entire bottom is then abrasive-blasted to achieve the required surface profile. AmTech installs either a fiberglass mat and resin (FRP) floor pan built up in layers, or a spray-applied DuraChem® 500 series polylining floor pan that cures instantly and creates a seamless corrosion-resistant barrier. This process is common on petroleum storage tanks, chemical tanks, and industrial process tanks.

AmTech repairs both steel and fiberglass tanks. For fiberglass (FRP) tanks, crews perform visual and structural inspections to identify cracks, delamination, blistering, UV degradation, chemical attack, and nozzle damage. Repairs use custom-assembled laminate systems with glass, Kevlar, or carbon veils and polyester, vinylester, or epoxy resins selected based on the stored substance and operating temperature. Structural laminate buildup restores wall thickness and integrity. Damaged nozzles are removed, rebuilt, and properly bonded to eliminate leaks. All materials are assembled on-site to match the tank's original construction.

Manway retrofitting involves welding a code-compliant 22-inch human access opening with an 18-bolt cover onto an existing steel tank that lacks adequate access. Many older tanks were built without manways, making inspection, cleaning, lining, and maintenance difficult or impossible. A retrofitted manway enables crews to enter the tank for future work, extending its useful life and ensuring compliance with API, NFPA, and local regulations. This service is commonly performed on single-wall and double-wall above-ground and underground storage tanks.

For emergency leak mitigation, AmTech uses Poly Lining Systems PLS 755 Tank Tape—a specialized industrial tape with ultra-strong, instant-bonding adhesive designed for tank repair. The tape is applied by hand to seal leaks, bridge gaps, and smooth irregular surfaces around pipe penetrations, nozzles, and weld seams. It is compatible with all AmTech lining systems including DuraChem® polylinings, HydraStone® Alkrete cement linings, and fiberglass systems. In addition, crews carry instant-cure DuraChem® 500 series materials and fiberglass laminate repair kits to provide permanent solutions on-site.

Yes. AmTech provides welding and tanker repair services across all 50 US states, Canada, and the Caribbean. The company operates its own engineer-led field crews rather than using subcontractors, ensuring consistent quality and compliance regardless of project location. Emergency repair services are available throughout this service area with rapid deployment capability to minimize facility downtime and address urgent tank integrity issues wherever they occur.
