In most cases, Diamond Fiberglass can provide its single wall storage vessel as a double wall option for catastrophic containment of chemicals.  This option is useful for tank retrofits where secondary containment is required but a containment basin is not present or feasible to install.

As the design standards for single wall tanks do not cover double wall designs, Diamond’s proprietary design provides full structural reinforcement of the secondary wall.  An interstitial space is present for customer’s to install their leak detection equipment.
