Containment Solutions ReTank® is an on-site retrofit system for existing fiberglass or steel single-wall tanks. For the Brochure CLICK HERE

• The ReTank system allows you to turn any Containment Solutions (or Owens Corning) single-wall tank into a hydrostatically monitored double-wall tank.
• It also allows you to go inside your existing steel tank and build a fiberglass single-wall tank – without removing the tank from the ground!
• Benefits include reducing costs of tank replacement, using existing tanks for dual fuels, and eliminating the worry of leaking/environmentally unsafe bare steel tanks.

With CSI's ReTank system a fiberglass inner tank is constructed in sections, and then installed in your existing tank while it is still in the ground. While in your tank, CSI technicians perform a full inspection, upgrade all fittings to current standards, and install all the safeguards of our newest double-wall tanks (single-wall tanks when installed in steel). You get the benefits of the safest fiberglass tanks - which never rust - for a much lower investment.

ReTank in Fiberglass

• Minimizes downtime to about one week to retrofit three, 10,000-gallon tanks
• UL Listed ReTank
• A new 30-year warranty on the ReTank
• Installing a second fiberglass tank, within an existing fiberglass tank, gives you double the protection with:
  
  
  • Proven corrosion and structural performance
  • Proven compatability with methanol, ethanol and all oxygenated motor fuels (See warranty)
  • Future access to all tank top fittings and equipment
  • Hydrostatic pressure, air pressure, vacuum, or dry sensor monitoring of annular space
  • Hydrostatic Monitoring - By installing the optional reservoir, the brine solution can be added. This solution is dyed a deep green and is easy to detect should there be a breach of the inner tank.
    
    Throughout the life of the tank, brine solution continuously monitors the integrity of both tank walls. If optional electronic monitoring systems are installed, an alarm will sound if the brine level changes.
    
    Optionally, air pressure can be applied to the annulus and a soap inspection of the inner tank performed.

ReTank in Steel

Containment Solutions' patented ReTank system fits inside an existing 96-inch or smaller steel tank. The steel tank is taken out of service and the fiberglass ReTank system is installed.

• No cathodic protection
• No relining
• No costly old tank removal

This process provides a finished, rust-free, single-wall fiberglass tank installed by Containment Solutions. New piping is installed by your installation contractor. Upon completion, your finished product is a UL Listed single-wall fiberglass tank with a 30-year warranty.

Future Access

Many single-wall tanks have no manways, but the ReTank system provides two for future access. The manway covers consolidate all fittings to simplify maintenance. The concentric collars and tank sumps also serve as a termination point for secondary containment piping.
