In-Situ Double Wall Fiberglass Tank Construction
Florida DEP Approved Tank EQ# 979
The Rafibra Systems converts a single wall tank to a double wall tank within the existing tank with an interstitial space that can be continuously monitored.
The work consists of manufacturing a double wall tank inside an old tank, with a permanent leak detection solution, transforming a single wall tank into a double wall one.

The Rafibra System is used on:
-
Underground and aboveground storage tanks
-
Vertical and horizontal fuel tanks
-
Retail and private fueling stations
-
Oil refineries, Petrochemical and other fuel storage facilities
-
Double wall tanks which are past their life expectancy
-
Single wall steel and fiberglass tanks being converted to double wall tanks
Advantage of our Method:
-
The process takes only 7 days per tank as opposed to an average of 2 months for the traditional tank replacement project
-
Project can be scheduled within weeks as opposed to several months for a tank replacement
-
The structural strength is superior and without a match in the industry and can withstand a pressure test of 70 PSI. A typical shop fabricated tank can only withstand 3 to 5 PSI
-
Most cities and towns do not require special construction permits and approvals for this system
-
Does not have the risk of “change orders” for shoring or dewatering often part of a traditional tank replacement project
-
The cost is less than half of a traditional tank replacement
-
Facilities can remain open while the tanks are built in-situ
Frequently Asked Questions About The Rafibra Technology
1. Can you reline a single-wall tank? Yes, the Rafibra system can be used on both single-wall and double-wall tanks.
2. Can you reline an existing fiberglass tank? Yes, we can reline both fiberglass and steel tanks, reinforcing them for long-term use.
3. What is the cost difference between replacing an underground tank versus installing a Rafibra double-wall lining? A Rafibra double-wall lining costs about 1/3 of the price of a traditional replacement, which requires excavation and new tank installation.
4. How do you test the new system to ensure its integrity? During installation, we perform multiple tests, including vacuum pressure testing of the interstitial space. This vacuum is left in the tank permanently—if pressure ever drops, an alarm alerts the facility, providing continuous leak detection.
5. Can you install a double-wall lining on underground and aboveground tanks? Yes, the Rafibra system works for both underground and aboveground tanks, ensuring compliance and durability.
6. How long does it take to complete a Rafibra double-wall relining on a 10,000-gallon tank? The process takes approximately 7-10 days per tank, significantly reducing downtime compared to traditional tank replacement.
7. How long is the warranty? We offer a 10 to 30-year limited warranty, depending on whether it is a single-wall or double-wall installation.
8. How do I choose between a new double-wall lining or a single-wall lining?
-
If your system is single-wall, we recommend upgrading to a double-wall system with interstitial space monitoring for added protection.
-
If your tank is within its 30-year life expectancy, a double-wall system is recommended to ensure long-term reliability.
-
If your existing double-wall tank has water in the interstitial space, it may indicate an outer wall failure, in which case we recommend upgrading to a double-wall system.
-
If your existing double-wall tank has product in the interstitial space, a single-wall lining can be used to fix the tank.
