ZCL’s underground fiberglass tanks are constructed of non-corrosive FRP composite material and premium quality grade resin. They are marketed under the trade names Prezerver®, and Greentank® and are available in both double wall and single wall options as well as in one, two or three compartments. Safe and durable, ZCL fiberglass tanks have become the #1 choice for environmentally safe storage of petroleum products.


  • ZCL's underground fiberglass tanks are manufactured with corrosion-resistant materials inside and out which eliminates the possibility of leaks caused by internal or external rust.
