These modifications include repairs & modifications, tank recertification, primary steel tank corrosive barriers, relining tanks, bio-fuel tank upgrades, and tank sump upgrades. Each item listed above will be detailed as follows:

Repairs & Modifications
• Modifications of existing tanks
• Installation of collars and tank sumps on existing tanks
• Repair of tank damage
• Repair and replacement of fittings

Tank Recertification
Tank recertification is a cost effective and environmentally conscious alternative to the purchase of a new double-wall tank in certain applications. If a tank is removed from an installation, moved to owner's new location and is intended for active service at the new location, the tank must be recertified in order to maintain the existing warranty as originally extended.

Primary Steel Tank Corrosive Barrier
This corrosive barrier is an FRP barrier between the primary steel tank and the product being stored. PSF offers three economical solutions to your corrosion issues. With our most extensive procedure providing incredible structural integrity to your steel tanks, PSF offers an economical solution to your company that far exceeds any solutions offered in the industry. Installing our new innovative corrosive barrier will add years of service to your existing storage tanks.

Bio-Fuel Tank Upgrades
Bio-fuel tank upgrades are a cost-effective solution for upgrading existing fiberglass tanks to meet new regulations. Many of the earliest generation fiberglass tanks were not tested nor were they warranted for either bio-diesel or ethanol blends exceeding 10%.

Tank Sump Upgrades
Some UST regulations require all components of the UST system to be "product tight" and be periodically tested for tightness. Studies funded by the state of California determined between 25% and 50% of underground tank sumps were leaking.
If a tank's sumps require upgrading from a non-sealed model to a watertight and testable model, the procedure is simple and effective:

1. Cut away existing top
2. Install a new watertight reducer and watertight lid inside
    the existing top then seal to existing piping
3. Perform tightness test
