Underground Fiberglass Water Storage Tank Solutions

Underground fiberglass water storage tank solutions include inspection, repair, relining, nozzle modification, and maintenance for FRP tanks used to store potable water, deionized water, and process water. The goal is to restore structural and lining integrity, extend service life, and avoid unnecessary replacement when a targeted repair or full lining restoration can safely keep the tank in service.

Common warning signs include liner spidering, soft or worn corrosion barriers, abrasion, emulsification, low Barcol hardness, weeping, nozzle-interface issues, floor stress cracking, shell distortion, or evidence of liquid migration beneath the lining. AFTR uses visual, ultrasonic, laser, and high-intensity backlight testing to identify whether localized repair, full relining, or additional structural work is recommended.

In many cases, yes. If the tank shell remains suitable and damage is limited to the lining, corrosion barrier, nozzles, or localized structure, repair or relining can add years of service life. This approach preserves the original capital asset, avoids long lead times for new vessels, and reduces disruption compared with removing and replacing an installed tank.

Yes. AFTR services FRP tanks storing potable water, deionized water, and general process water for municipal, industrial, and food-and-beverage applications. Resin and veil systems are selected for the specific water chemistry and potable-contact requirements when applicable, followed by post-cure inspection and service-readiness checks to support safe return to operation.

AFTR inspections may include visual examination, instrument testing, ultrasonic evaluation, laser measurement, high-intensity backlight testing, and Barcol hardness checks. These methods help reveal surface degradation and hidden issues inside the structural body, including capillary migration beneath the corrosion coat. Reports include findings and practical recommendations for repair, relining, monitoring, or maintenance.

Timing depends on tank size, access, contamination level, repair scope, cure requirements, and whether nozzle or manway modifications are included. AFTR plans projects around customer operations, including shutdowns, night shifts, and weekends when needed. The team’s stocked resins, laminates, and Service-Pack containers help crews begin work efficiently once mobilized.

Yes. AFTR offers year-round flexibility and can schedule routine service, planned outages, maintenance, and repair work around customer shutdowns, night shifts, weekends, and operational windows. Crews can also heat or cool the tank and work area when ambient conditions would otherwise delay repair, helping customers minimize downtime and production disruption.

American Fiberglass Tank Repair serves customers across all 50 U.S. states, including Hawaii and Puerto Rico, as well as Canada, Mexico, the Caribbean, and select international locations. Field service teams and strategically positioned personnel support routine projects and emergency response for municipal, waterworks, wastewater, chemical, and industrial FRP tank owners.
