Double Wall Fiberglass Tanks
The inner and outer walls and specifically designed ribs of CSI’s double-wall fiberglass tanks act together to form a structural system that has earned the UL 1316 listing as a true double-wall tank.

Double-Wall features for environmental safety:

True double-wall construction means high strength.
Secondary containment provides 360 degrees of protection you can count on.
Tanks are available with dry or wet monitoring of the annular space and will detect leaks in inner and outer walls under all conditions.

State-of-the-art protection:
Our Double-Wall Tanks deliver state-of-the-art protection. CSI’s advanced double-wall technology gives owners, municipalities, counties and states proven protection against petroleum contamination of underground water supplies. In addition to our UL listing, our tanks comply with the American Petroleum Institute’s recommendation for secondary containment systems wherever underground tanks are located within 300 feet of underground water supplies.

As liabilities associated with leaking fuels soar, UL-listed fiberglass Type II Double-Wall Tanks for underground storage applications provide you with your best long-term protection.

The ultimate in risk management:
Don’t settle for less than the ultimate in risk management. Type II Double-Wall Tanks give you two levels of protection, so you have twice the assurance and twice the risk management that any single-wall tank can offer. The primary tank is designed to contain your fuel. In the unlikely event that there is a breach in this wall, the secondary wall is designed to contain your product and prevent a spill into the environment.

System testing and monitoring:
System testing assures you of product tightness. Continued assurance of the integrity of our double-wall tanks can be determined by testing at the jobsite – prior to and after installation – to prove the durability and product tightness of both the primary and secondary tanks. With some competitive tanks, the secondary walls or jackets cannot be tested after the tanks have been installed.

Continuous monitoring and precision tank-testing capabilities are built in. Because it is comforting to be able to test the ongoing integrity of any storage tank, CSI built into each of our double-wall tanks both continuous monitoring and precision tank-testing capabilities.

Our Type II Double-Wall Tanks provide a defined annular space to accommodate virtually any type of monitoring method you choose — wet or dry. Our tanks can be supplied with a factory installed Hydrostatic Monitoring System with a brine monitoring fluid. The brine is a dark green color preinstalled in the interstitial space at the factory and is used to perform visual leak testing during shipment and at the jobsite.

Hydrostatic Monitoring System:
We recommend the Hydrostatic Monitoring System because it offers a leak detection capability that is superior to other methods. It constantly monitors 100% of both the inner and outer walls under all installed conditions. Most steel tanks do not offer this feature. The Hydrostatic Monitoring System can also double as a precision tank test, which has been independently tested and validated to meet EPA precision tank-testing requirements, able to detect leaks as small as 0.1 gallons per hour. The precision tank-testing procedure is easy to perform and consists of a few simple steps.

Our fiberglass tanks have been exhumed after 6, 12, 15 and 21 years of gasoline service and have shown no loss in their original (structural) properties.
