Field FRP Tank Relining and Corrosion-Barrier Restoration
Troy Dualam Services performs field relining and corrosion-barrier restoration for FRP tanks whose internal protective system has deteriorated. Relining renews or replaces the internal protective lining or corrosion-barrier system. It does not restore structural capacity. If the structural laminate is damaged, the structural condition must be separately assessed and any required repair or reinforcement completed before the new lining system is applied. Replacement may be required if the substrate is not repairable.
On this page, restoration means restoration of the tank’s internal protective system. It does not mean that structural capacity has been restored.
FRP Tank Relining Scope
A field relining scope may include:
- Tank condition assessment and review of the existing lining
- Surface preparation suited to the agreed scope
- Service-specific lining or corrosion-barrier selection based on the documented fluid or mixture, concentration, temperature, contaminants or solids, cleaning and upset conditions, duty cycle, substrate condition and other relevant operating requirements
- Application of the new internal lining or corrosion-barrier system
- Final inspection and documentation suited to the agreed scope
If condition assessment identifies damage in the structural laminate, a separate structural FRP repair or reinforcement scope must be developed, subject to adequate design information and any required engineering review. Required structural work must be completed before relining; replacement may be recommended if the substrate is not repairable.
Field Relining Scope and Downtime Planning
This page covers relining performed at the client’s site. Depending on tank size, access, transportability, condition and required controls, TDS may recommend field work, shop work or replacement.
For field work, the tank and work area must be prepared for safe access. The tank may need to be isolated or locked out, drained, cleaned, decontaminated, ventilated and taken out of service while surface preparation, application, cure or post-cure are completed. Gas testing, confined-space controls, fall protection and permits may also be required.
Service-Specific Lining Selection
Relining material selection considers the documented fluid or mixture, concentration, temperature, contaminants or solids, cleaning and upset conditions, duty cycle, substrate condition and other relevant operating requirements.
Relining renews or replaces the internal protective lining or corrosion-barrier system; it does not restore structural capacity. If the structural laminate is damaged, the condition must be separately assessed and any required structural repair or reinforcement completed before relining. Replacement may be required if the substrate is not repairable.
- Renewal or replacement of the internal protective lining or corrosion-barrier system.
- Tank and existing-lining condition assessment.
- Field execution planned around access, isolation or lockout, decontamination, ventilation, permits and cure requirements.
- Material selection based on documented service variables, substrate condition and operating requirements.
- Structural laminate condition separately assessed and any required structural work completed before relining.
Extend Service Life When the Laminate Remains Serviceable
When the structural laminate remains serviceable and the lining is selected for the documented service, relining can extend the tank’s service life by many years. The actual extension depends on equipment condition, service exposure, surface preparation, workmanship, operation and inspection.

Frequently Asked Questions About FRP Tank Relining
Relining renews or replaces the tank’s internal protective lining or corrosion-barrier system. It does not restore structural capacity. If the structural laminate is damaged, the condition must be separately assessed and any required repair or reinforcement completed before the new lining system is applied. Replacement may be required if the substrate is not repairable.
Relining may be considered when the structural laminate remains serviceable and the internal protective lining or corrosion-barrier system has deteriorated. The recommendation depends on tank condition, service requirements, access and repairability.
TDS can assess industrial FRP storage tanks, process tanks, water and wastewater tanks, and related vessels. Suitability depends on construction, condition, access and documented service.
Relining material selection considers the documented fluid or mixture, concentration, temperature, contaminants or solids, cleaning and upset conditions, duty cycle, substrate condition and other relevant operating requirements.
No. This page covers relining performed at the client’s site. Depending on tank size, access, transportability, condition and required controls, TDS may recommend field work, shop work or replacement.
Our Benefits
TDS defines a field relining scope from tank condition, documented service, access and site requirements. Relining renews or replaces the internal protective system; structural laminate assessment and repair remain a separate scope.
Our History
Decades in the making. Founded in 2021, Troy Dualam Services draws on the combined FRP experience and heritage of the Troy Dualam group.
