Underground Tank Technology

The Plasteel® Double Wall Composite Tank is UL Listed and Tested per UL Standard 58 and UL Standard 1746, Part II, Type I and Type II Secondary Containment. The outer steel secondary containment tank is assembled and welded 360° around the inner primary tank creating an interstitial space. The interstitial space between the primary tank and the secondary containment tank is designed to provide access to detect a liquid in the interstitial space and containment of the liquid.
