History of Fiberglass:

  • During the early 20th century, in the interest of public safety, it became common practice to install steel fuel storage tanks underground.
  • By the 1960s it had become obvious that internal and external corrosion was causing leaks and environmental damage.
  • The leading composites developer of the time, Owens Corning, got to work developing a dependable solution.
  • In 1964, they released the Fiberglas® Tank, the first of its kind, made of corrosion resistant, non-degrading fiber reinforced plastic, or FRP.
  • In 1984, the next level of storage safety was introduced with the first double-wall underground fiberglass tank, providing another layer of protection.
  •  In 1988, the Federal UST Regulations were introduced, setting legal environmental standards for the entirety of the oil and gas industry.


History of Containment Solutions:

In the interest of refocusing on their core businesses, Owens Corning sold the assets of its tank division in 1994, which became what is now Containment Solutions, Inc.


Since then:

  • We’ve taken the company to new heights.
  • The same year we were formed, we introduced our line of water tanks under the Flowtite® brand name.
  • In 2004, we introduced the Hydroguard ® System
    • A system that combines a proven technology of double-wall fiberglass tanks with the advanced protection of double-wall tank sumps in a hydrostatically monitored environment.
    • See our HydroGuard® System section for more information.
  • In 2016, we opened a new 160,000 Sq.Ft. Manufacturing facility in Tulsa, Oklahoma.


With more than 50 years of experience and hundreds-of-thousands of tank installations, we continue to develop new techniques, utilizing today's automation processes to improve upon our already high-quality manufacturing procedures.
