Underground storage tanks are naturally placed under a variety of harsh conditions from both the internally contents and the external environment. Fiberglass tanks provides unprecedented reliability, strength, and durability at a competitive cost. Carlson Engineered Composites’ provides industry-leading, high-quality, and durable fiberglass underground tanks that offer end-users with long-term peace of mind. These tanks are typically used for septic, water, chemical storage, or other applications.

Why Carlson Engineered Composites UGT?

Our fiber-reinforced plastics (FRP) underground tanks (UGT) have been engineered to exceed industry standards and requirements. Our UGTs can be designed to suit virtually any application and can be customized with a large list of options and accessories. Our standard lineup of CSA-approved UGTs range from 750 to 12,000 imperial gallons.

Unlike other tank manufacturers that consider the corrosion barrier as a part of the structural layers of the tank, Carlson Engineered Composites manufactures fiberglass tanks with a corrosion barrier that is in addition to the structural component of the tank. This means that the tank will maintain its structural integrity even if the corrosion barriers is compromised after decades of service.
