FRP Tank Repair and Rehabilitation

Restoring Fiberglass Tank Performance Without Replacement

Fiberglass Reinforced Plastic (FRP) tanks are widely used in industrial environments for their corrosion resistance and chemical compatibility. Over time, FRP tanks can experience structural degradation, chemical attack, UV exposure, and mechanical damage that compromises performance and containment integrity.

RAK Industrial Services provides FRP tank repair and rehabilitation solutions that restore structural strength, rebuild internal corrosion barriers, and extend the service life of fiberglass tanks, eliminating the need for costly replacement or extended downtime.

Our team evaluates tank condition, identifies failure points, and implements targeted repair strategies designed to return FRP systems to safe, reliable operation in demanding industrial environments.

Secondary containment restoration

Each repair is designed to restore both structural integrity and chemical resistance, ensuring long-term performance under operating conditions.

Common FRP Tank Failures

FRP tanks often fail differently than steel tanks. Common issues include:

  • Delamination of fiberglass layers
  • Cracking due to stress or impact
  • Chemical attack degrading resin systems
  • Blistering or softening of internal liners
  • UV degradation on exposed surfaces
  • Leaks at seams, nozzles, or penetrations
  • Structural weakening from long-term service exposure

These conditions can progress quickly if not addressed. RAK specializes in identifying root causes and applying repair systems that prevent continued deterioration.

Restoring Internal Linings and Corrosion Barriers

In many FRP tank projects, restoring the internal corrosion barrier is critical to long-term performance. Without a properly functioning liner, the structural laminate is exposed to chemical attack and premature failure.

RAK selects lining and barrier systems based on the specific service environment, including chemical exposure, temperature, and process conditions. These systems are designed to protect the tank interior while maintaining compatibility with the existing structure.

When properly applied, these linings restore protection, extend service life, and reduce the likelihood of recurring damage.

Application-Focused Solutions
Lining systems are selected based on real operating conditions including chemical exposure, temperature, and service demands to ensure long-term compatibility and performance.

FRP Tank Applications

RAK works on a wide range of fiberglass tank systems across industrial environments, including:

  • Chemical storage tanks
  • Wastewater and treatment tanks
  • Process and mixing vessels
  • Neutralization and reaction tanks
  • Secondary containment structures
  • Scrubber and emission control system tanks
  • Custom FRP vessels exposed to aggressive operating conditions

Each system presents unique challenges, and repairs are developed to address the specific demands of the application while maintaining safe and reliable operation.
