Expert FRP Tank Corrosion & Blistering Repair

A fiberglass tank’s life expectancy depends on its chemical service, temperature, laminate design, maintenance history, and condition of the corrosion barrier. With proper inspection, timely lining repair, and compatible resin systems, many FRP tanks can remain in service for decades. Early repair of blistering, spidering, or liner breaches can add years of useful life and help avoid full replacement.

Yes. FRP tanks rely on an interior corrosion barrier to protect the structural laminate from stored chemicals or process liquids. When that barrier blisters, cracks, wears, or allows capillary migration, the tank can weaken over time. Corrosion protection may include compatible resin systems, veil layers, inspection programs, and relining matched to the chemical, concentration, and operating temperature.

Blistering often occurs when liquid, vapor, or chemical components migrate into or behind the corrosion barrier. Contributing factors can include chemical incompatibility, excessive operating temperature, mechanical abrasion, poor historical repairs, or aging laminate. Once blisters appear, the affected lining should be evaluated because hidden disbondment or capillary migration may be present beneath the visible surface.

In many cases, yes. If the structural body remains suitable, the compromised corrosion barrier can often be removed, prepared, and rebuilt with product-specific resin, veil, and laminate systems. Inspection is essential to determine whether the damage is limited to the lining or has affected the structural laminate, nozzles, floor, or shell.

FRP corrosion inspections typically include examination of the interior corrosion coat, structural body, exterior shell, nozzles, and interfaces. AFTR may use visual methods along with ultrasonic, laser, high-intensity backlight, and Barcol hardness testing. These methods help identify spidering, disbondment, emulsification, abrasion wear, shell distortion, and migration beneath the liner.

Repair materials are selected based on the stored product, chemical concentration, operating temperature, and original tank construction. AFTR works with custom-blended isophthalic and terephthalic polyester, vinylester, and epoxy resins, plus more than 45 fiberglass mat, chopped strand, Nexus, Harlar, and carbon veil laminates for application-specific corrosion resistance.

Yes. AFTR schedules field repair, maintenance, inspection, and relining around operational needs, including planned shutdowns, night shifts, weekends, and emergency situations. Crews mobilize with materials and equipment needed to begin work efficiently, helping facilities minimize production disruption while restoring tank integrity.

Yes. AFTR provides 24/7 emergency FRP tank repair for unexpected failures, impact damage, severe liner compromise, and other urgent issues. Strategically positioned personnel and equipped Service-Pack containers support rapid mobilization across North America. Emergency assessment determines whether lining repair, structural repair, or additional remediation is needed before safe return to service.
