Expert coating & sealing bolted storage tanks

Coating and sealing a bolted storage tank typically includes inspection, cleaning, surface preparation, joint and penetration sealing, coating or lining application, and final verification. AmTech evaluates the tank’s substrate, stored product, corrosion condition, and operating environment before selecting systems such as DuraChem, HydraStone, Armor Shield, AT BiFlex, PLS 755 Tank Tape, or crystalline waterproofing products.

Surface preparation determines how well a coating or lining bonds to the tank. Rust, oxides, mill scale, old coatings, moisture, and contaminants can cause premature failure if left behind. AmTech uses abrasive blasting, wet blasting, hydroblasting, or power-tool profiling, then verifies surface profile, humidity, temperature, and dew point against industry requirements before application begins.

Yes. Bolted seams, nozzle openings, pipe penetrations, weld transitions, and uneven joints are common weak points in storage tanks. AmTech uses preparation methods and compatible materials such as PLS 755 Tank Tape to bridge gaps, smooth transitions, and reduce voids beneath the coating. This helps create a continuous surface for long-term lining adhesion.

AmTech specifies lining systems based on tank material, stored liquid, temperature, corrosion exposure, and mechanical stress. Options include DuraChem 500 series 100% solids poly linings, HydraStone Alkrete cementitious linings, Armor Shield coatings, AT BiFlex fiberglass systems, Port Seal, and Xypex crystalline waterproofing. Each system is selected to match the tank’s service environment.

Yes. AmTech provides chemical and wastewater tank lining services for corrosive, acidic, alkaline, biological, and abrasive environments. DuraChem 500 series linings form seamless monolithic barriers that resist aggressive exposure, including fluctuating pH, hydrogen sulfide, suspended solids, and many industrial chemicals. Field engineers review the stored product and operating conditions before specifying the lining.

Downtime depends on inspection findings, cleaning requirements, steel or concrete repair needs, surface preparation, tank size, and the selected coating system. Some AmTech systems, including DuraChem 500 series polylinings, cure instantly on contact and can reduce extended shutdowns compared with traditional multi-coat epoxy or vinyl ester systems that require longer cure windows.

Yes. AmTech provides emergency tank repair for active leaks, corrosion breakthrough, lining failure, nozzle blowouts, structural cracks, and compliance-related shutdowns. Crews can mobilize with proprietary lining materials, PLS 755 Tank Tape for temporary sealing situations, and welding equipment for structural steel repairs, helping facilities stabilize the issue and restore safe operation.

AmTech’s experienced field crews serve facilities across all 50 US states, Canada, and the Caribbean. The company works with municipal, industrial, commercial, petroleum, chemical, water, wastewater, manufacturing, institutional, and government facilities. Because crews travel to the tank site, projects can be planned around operating schedules, shutdown windows, and emergency response needs.
