Interstitial Fiberglass Tank Leak Detection Sensors

Interstitial fiberglass tank leak detection sensors are monitoring components used to identify liquid intrusion or leakage between tank layers, containment spaces, or designated monitoring points. In FRP vessels, they are often paired with inspections of the corrosion barrier, structural laminate, nozzles, and interfaces to determine whether an alarm reflects true product migration, liner failure, or another condition requiring repair.

Leak detection sensors are worth considering when a tank stores corrosive chemicals, potable or process water, wastewater treatment chemicals, or products where early warning is critical. They are especially useful for aging FRP tanks, vessels with prior lining repairs, tanks exposed to changing chemistries, or facilities trying to reduce unplanned downtime through proactive monitoring and inspection.

In many cases, monitoring upgrades can be evaluated for tanks already in service, but the approach depends on tank design, access, laminate condition, chemical exposure, and containment configuration. AFTR can assess the vessel, inspect relevant surfaces, and coordinate sensor-related work with lining repair, nozzle modification, or structural laminate restoration when needed.

A sensor alarm should be verified with a structured tank condition assessment rather than assumptions. AFTR may examine the interior corrosion coat, exterior shell, nozzles, and suspected migration paths using visual and instrument methods, including ultrasonic, laser, and high-intensity backlight testing. The goal is to determine whether liquid has migrated beneath the lining or if another issue caused the reading.

Sensor-related inspections can uncover corrosion-coat breaches, spidering, disbondment, abrasion wear, emulsification, low Barcol hardness, stress cracking, shell distortion, ultraviolet degradation, and capillary migration of product beneath the corrosion barrier. Identifying these issues early often allows targeted relining or laminate repair before the tank requires replacement.

Yes. AFTR provides FRP tank lining, structural laminate repair, nozzle repair, emergency response, and chemical-specific relining services. Repairs may include removal of compromised corrosion coat, substrate preparation, installation of compatible veil and resin systems, cure, inspection, and documentation. The repair plan is matched to the stored chemical, concentration, temperature, and tank condition.

Yes. AFTR works around customer schedules, including planned shutdowns, night shifts, weekends, and operational windows where downtime is least costly. Crews can mobilize for routine inspection, planned maintenance, or urgent issues, and they carry resin and laminate inventories that help field teams begin appropriate FRP work efficiently after assessment.

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. The company’s field service model supports chemical plants, water and wastewater facilities, food processing operations, industrial sites, and other organizations operating FRP storage vessels.
