Double-Wall Fiberglass Tanks

Double-Wall Storage Tanks

FRP/Mocoat is a leading manufacturer of double-wall fiberglass tanks – both above ground and below ground throughout North America. Our projects start with proper engineering design in conjunction with customer-specific requirements. Typically, an in-house autocad drawing will be generated for approval and involves a sign off from a professional engineer registered in the province or state that the tank will be put into service.

The interstitial space is composed of a 3D fabric providing for continuous monitoring of the interstitial space while also providing continual laminating support to maximize strength. Each primary tank is tested and the interstitial space is also tested using either a pressure or a vacuum test.

Unlike steel, it will not rust or corrode. Unlike concrete it is lightweight and not subject to deterioration.
