In the United States, if you store over 250 US gallons of fuel for commercial purposes you must ensure it is in a storage vessel that is double-walled.
Some states may allow a single skin storage tank but that must be contained within a self-contained bunded (upstand) construction for spillage containment.
Bunded areas should be sized to hold 110% of the capacity of the largest storage tank and are traditionally constructed from concrete or masonry adding to project costs and build times.
UNITY BLOC TANKS REMOVE THE NEED FOR TRADITIONAL BUND WALL CONSTRUCTION AND CONTAINMENT.
Our BLOC series double-wall fuel tanks are designed as integral secondary containment and therefore do not require traditional bunded wall containment areas for leak containment.
BLOC Double-walled Tank = 100% Primary Tank + 10% interstitial space, which equates to a bunded area of 110% of the storage tanks capacity.
