Epoxy Lining an Existing Tank: Pros and Cons
Underground storage tanks (USTs) play a crucial role in industries such as fuel storage, chemical processing, and waste management. Over time, however, even the most durable tanks can suffer from corrosion, leaks, or structural wear. One cost-effective solution for extending the lifespan of an existing tank is through epoxy lining. But is it the right choice for your UST? At Herbert Lutz & Company, we help businesses in New Jersey and Florida make informed decisions about their storage solutions. Here, we break down the pros and cons of epoxy lining for USTs. Contact us for assistance with lining and coating or other vital UST services.
What Is Epoxy Lining?
Epoxy lining is a protective coating applied to the interior surface of a tank. This thick, chemically resistant material creates a barrier that prevents corrosion, leaks, and contamination. Applied in liquid form, epoxy cures into a hard, durable shell that adheres directly to the tank walls, providing a strong layer of protection.
Pros of Epoxy Lining an Existing Tank
1. Extends Tank Lifespan
Epoxy lining can significantly prolong the life of a UST by preventing corrosion and structural degradation. This is particularly valuable for older tanks that are still structurally sound but need added protection.
2. Cost-Effective Solution
Compared to replacing an entire tank, epoxy lining is far more affordable. It allows businesses to maximize the use of their existing infrastructure without the higher costs and downtime associated with tank replacement.
3. Regulatory Compliance
USTs must meet strict environmental regulations, especially concerning leak prevention. An epoxy lining can help tanks meet regulatory standards by creating an impermeable barrier that minimizes the risk of leaks and groundwater contamination.
4. Faster Turnaround Time
Installing a new tank can take weeks, whereas epoxy lining typically involves minimal downtime. This allows businesses to get their operations back up and running quickly.
5. Chemical Resistance
Epoxy coatings offer excellent resistance to many chemicals, including petroleum products and industrial solvents. This makes them ideal for tanks storing harsh substances.
Cons of Epoxy Lining an Existing Tank
1. Not a Permanent Fix
While epoxy lining extends the lifespan of a tank, it isn’t a permanent solution. Over time, the lining can degrade, especially if the tank is exposed to extreme temperatures, pressure fluctuations, or highly aggressive chemicals. Regular inspections and maintenance are still necessary.
2. Requires a Structurally Sound Tank
Epoxy lining can only be applied to tanks that are structurally intact. If a tank has severe corrosion, cracks, or compromised integrity, lining will not be a viable solution, and replacement might be necessary.
3. Surface Preparation Is Critical
The success of an epoxy lining depends heavily on proper surface preparation. The tank must be thoroughly cleaned, dried, and sometimes sandblasted to ensure the epoxy adheres correctly. Poor preparation can lead to early failure of the lining.
4. Limited Compatibility
Certain chemicals can break down epoxy linings over time. It’s essential to ensure that the materials stored in the tank are compatible with epoxy coatings.
5. Potential for Application Errors
If the epoxy is not applied correctly, issues such as bubbles, uneven coverage, or weak adhesion can arise. It is crucial to hire experienced professionals to ensure a proper and effective application.
Is Epoxy Lining Right for Your Tank?
Epoxy lining can be a smart, cost-effective solution for extending the life of a UST. However, it’s not a one-size-fits-all fix. Factors such as the condition of your tank, the substances it stores, and regulatory requirements should all be considered.
At Herbert Lutz & Company, we specialize in providing expert UST services, including tank installation, removal, maintenance, and repair in New Jersey and Florida. Our team can assess your tank’s condition and help you determine whether epoxy lining is the best option for your needs.
